The checklist includes a listing of the genera and species of North American Bryophyta thought to occur in the continental United States and Canada. The floras of Mexico, Hawaii and Greenland are not included. The current list recognizes 1565 species, 12 subspecies, 34 varieties and one form (for a total of 1612 taxa) in 366 genera and 100 families. As a preface to the list, a systematic arrangement of the families and included genera for North America is presented. Many changes from the previous checklist are documented via footnotes that provide references to where changes were made. Only synonymy since the previous checklist is included. Twenty nomenclatural changes are made. These include 19 new combinations: Bryum brassicoides (≡ Gemmabryum brassicoides), B. pacificum (≡ Ptychostomum pacificum), B. torenii (≡ Imbribryum torenii), B. vinosum (≡ Gemmabryum vinosum), Chionoloma maragniphyllum (≡ Oxystegus maragniphyllus), Lescuraea tribulosa (≡ Pseudoleskea tribulosa), Pterygoneurum 3kieneri (≡ P. subsessile var. kieneri Habeeb), Pylaisiadelpha canadensis (≡ Brotherella canadensis), Streblotrichum convolutum var. eustegium (≡ Barbula eustegia), Streblotrichum convolutum var. gallinula (≡ Barbula convoluta var. gallinula), Voitia angustata (≡ Splachnum angustatum), V. mnioides (≡ Splachnum mnioides), V. pallida (≡ Tetraplodon pallidus), V. paradoxa (≡ Splachnum paradoxum), V. urceolata (≡ Splachnum urceolatum), Warnstorfia badia (≡ Hypnum badium), W. straminea (≡ Hypnum stramineum), W. straminea var. patens (Lindb.) (≡ Amblystegium stramineum var. patens), W. wickesiae (≡ Calliergon wickesiae). A new order is also introduced: Rhizogemmales W.R.Buck & Goffinet (≡ Rhizogemmaceae Bonfim Santos, Siebel & Fedosov).
We present here the newest version of the North American moss checklist. In doing so, we stand on the shoulders of previous North American bryologists. Beginning with A. J. Grout (1940), who published the first comprehensive checklist of North American mosses, the task was then taken over by Howard Crum with the collaboration of Lewis Anderson and Bill Steere (Anderson 1990; Anderson et al. 1990; Crum et al. 1965, 1973). It has now been almost 35 years since the last checklist and our understanding of moss diversity, species delineation and phylogeny and its accompanying nomenclatural and classification changes have moved ahead faster than at any time in the past. Molecular data have revealed relationships previously undetected by morphological observations, and similarly may reveal that phenotypic divergences may be infraspecific rather than diagnostic of speciation events. Moss taxonomy is a dynamic field and hence changes are far from being finished and names will continue to change for the foreseeable future, as we can attest by the changes encountered during the two-year preparation of this list. Furthermore, some concepts remain contentious among authors (e.g., taxonomy and systematics of the Pottiaceae), and consequently we have had to make choices. While we aimed at considering the evidence of alternative hypotheses (e.g., strength of the data, whether morphological or molecular, in supporting lineages), in various cases the final decision may have been shaped by our own general concepts. However, the impacts of our perhaps subjective decisions affect primarily systematic rather than taxonomic concepts at the species level, and hence should have a minimal impact on the recognized diversity of species and infraspecific taxa in the continental United States and Canada.
Moss systematics historically has been driven by phenotypic divergences, which is obviously the first step in an effort to organize diversity. The difficulty arose from the weight attributed to specific characters to diagnose lineages. A good example is the genus Physcomitrella Bruch & Schimp. (Funariaceae). Distinguished from Physcomitrium (Brid.) Brid. by its indehiscent, immersed capsules, its circumscription varied in terms of species and rank (Tan 1979) and even its affinities to Aphanorhegma Sull., a unispecific genus also characterized by immersed but operculate capsules. Inferences from DNA sequence data, first from about ten loci (Liu et al. 2012) and then hundreds of organellar (Medina et al. 2018) and then nuclear loci (Medina et al. 2019a), revealed that immersed sporangia evolved multiple times within Physcomitrium, and hence recognizing Physcomitrella or Aphanorhegma resulted in a paraphyletic Physcomitrium. Consequently, all species with immersed capsules were transferred to Physcomitrium (Medina et al. 2019a).
When a genus diagnosed by morphological traits is resolved as paraphyletic, based on DNA data, for example, due to the inclusion of a small genus, a single genus should be recognized if monophyly is a criterion, such as in the above case of Physcomitrella and Physcomitrium. The single genus recognized should bear the earliest name available (e.g., Physcomitrium) as dictated by the International Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018). If the older name applies to a lesser-known genus, such priority can be overruled by a decision to conserve the younger name. Such is the recent case of Plagiomnium T.J.Kop. (Koponen 1968) being conserved over Orthomnion Wilson (Wilson 1857) at the recent congress in Madrid (Wilson 2024) on the basis that the former is “a well-established name for a widely distributed genus and therefore conservation would promote nomenclatural stability for the broad community of users of botanical names.” Whether to conserve a name is to some extent a subjective decision based on the perceived “usage” of the younger name. However, one can argue that the sooner a name is adopted the sooner it will gain in usage; the time ahead of us is much longer than the past two centuries of Linnean classification. The genus Voitia Hornsch. (1818) has traditionally accommodated two species, and phylogenetic inferences drawn from many nuclear loci (Lewis et al. 2014) reveal that their common ancestor arose from within Tetraplodon Bruch & Schimp. (1844), which was thus resolved as paraphyletic. Tetraplodon occurs primarily in the Northern Hemisphere with disjunctions in southern South America, and high elevations in Africa and New Guinea, whereas Voitia is confined to Laurasia, where it is largely sympatric with species of Tetraplodon (Marino 2014). Both genera belong to the Splachnaceae and have been studied in this context (see A. Koponen [1982, 1990] and Marino [1988, 1991a, 1991b] and Marino et al. [2009]). Both genera have been accepted since their protologues and their species have been included in all subsequent inventories. Merging the two genera translates morphologically into species with indehiscent capsules (diagnostic of Voitia) having arisen from Tetraplodon-like ancestor with dehiscent sporangia. Such a scenario has been accepted for Voitia grandis D.G.Long transferred to Tayloria (Goffinet & Shaw 2002) and is recurrent in other genera such as Physcomitrium (Medina et al. 2019a) or Weissia Hedw. (Reese & Lemmon 1965; Zander 1993).
Other genera, primarily speciose ones, have been broken up based on their polyphyletic resolution; examples include Brachythecium Schimp. (Brachytheciaceae; e.g., Ignatov & Huttunen 2002) and Hypnum Hedw. (Hypnaceae; Schlesak et al. 2018). The outcome may be the recognition of new unispecific genera (e.g., Buckia D.Ríos, M.T.Gallego & J.Guerra), which serve as placeholders pending completion of a more comprehensive taxonomic sampling of the speciose genera. We have reluctantly accepted all these segregates. In other cases, the splitting of genera reflects perhaps more subjective preferences, and may not be supported by phylogenetic evidence. For example, Racomitrium Brid. (Grimmiaceae) has been divided into several genera (i.e., the resurrected Bucklandiella Roiv. and Codriophorus P.Beauv. [Ochyra et al. 2003] and the newly proposed Dilutineuron Bedn.-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek [Bednarek-Ochyra et al. 2015], Frisvollia Sawicki, Szczecińska, Bedn.-Ochyra & Ochyra [Sawicki et al. 2015] and Niphotrichum (Bedn.-Ochyra) Bedn.Ochyra & Ochyra [Ochyra et al. 2003]). Although these generic segregates may be monophyletic, they all arose from a unique shared common ancestor, i.e., Racomitrium s.l. is itself monophyletic (Larraín et al. 2013). Hence, phylogenetically the recognition of smaller genera is not justified. Furthermore, these newer segregate genera lack unambiguous diagnostic morphological traits, given that their circumscription was dependent on DNA versus morphological character analyses (e.g., Bednarek-Ochyra et al. 2015, Sawicki et al. 2015). Hence, we recommend treating these lineages within Racomitrium as subgenera as originally proposed by Bednarek-Ochyra (1995). A similar case pertains to the Warnstorfia Loeske complex (Calliergonaceae), which comprises four genera, each accommodating only a few species: Loeskypnum H.K.G.Paul (2 spp.), Sarmentypnum Tuom. & T.J.Kop. (6 spp.), Straminergon Hedenäs (1 sp.) and Warnstorfia Loeske (4 spp.; Hedenäs 1993). Together these genera compose a monophyletic group (Hedenäs et al. 2005), which we propose recognizing at the generic level.
Another case of segregation of a new genus that can be avoided if a broader concept of the core genus is followed, is Anomodon Hook. & Taylor. Ignatov et al. (2019a) divided Anomodon into several genera. They erected Pseudanomodon for Anomodon attenuatus (Hedw.) Huebener because it was only distantly related to the clade comprising the type of Anomodon, i.e., A. viticulosus (Hedw.) Hook. & Taylor. We support recognizing Pseudanomodon. They also established the genus Anomodontopsis for Anomodon rugelii (Müll.Hal.) Keissl. because the latter is resolved as sister to a clade composed of Anomodon s.str. and Haplohymenium Dozy & Molk. Given the paraphyly of Anomodon, their proposal could be justified on phylogenetic grounds. However, Granzow-de la Cerda (1997) had previously argued for the merger of Haplohymenium with Anomodon; such a concept would restore the monophyly of Anomodon and hence make the segregation of Anomodontopsis unnecessary.
In its traditional circumscription, Bryum Hedw. is among the most speciose genera of mosses (Crosby et al. 1999). Some of its diversity was accommodated early on in distinct genera (e.g., Ptychostomum Hornsch. [Hornschuch 1824]; Plagiobryum Lindb. [Lindberg 1862]), but most have been transferred more recently into new generic segregates (i.e., Gemmabryum J.R.Spence & H.P.Ramsay [Spence & Ramsay 2005]; Imbribryum N.Pedersen [Pedersen 2005; Pedersen & Hedenäs 2005]; Plagiobryoides J.R.Spence [Spence 2005]; Rosulabryum J.R.Spence [Spence 1996]). The most recent phylogenetic analyses based on DNA data led Holyoak & Pedersen (2007) to merge Plagiobryum with Ptychostomum as well as other phylogenetic inferences, whether based on DNA (Pedersen & Hedenäs 2003; Wang & Zhao 2009) or morphological traits (Pedersen et al. 2007), thus raising doubts on the monophyly of the Bryum segregates, as recently also discussed by Toren et al. (2024). Consequently, we recognize a single, albeit morphologically diverse, genus, Bryum, pending a comprehensive taxonomic and data sampling to resolve the ambiguities.
Finally, generic concepts may be based on the integration of criteria other than strict monophyly. Zander (2024), for example, integrated functional information in the analysis of complexity leading him to recognize monothetic and fractal genera. Admittedly, we do not yet fully understand the conceptual basis for this approach. Therefore, we decided to not recognize the one new generic name that Zander (2023) applied to a taxon present in our flora, i.e., Neotrichostomum for Trichostomum crispulum Bruch.
Overall, we aimed for consistency in applying criteria for recognizing genera and understand that our concepts depart from those proposed or adopted by others, such as contributors to the Bryophyte Flora of North America (Flora of North America Editorial Committee 2007, 2014). In all cases, we sought to provide the basis or explanation for our systematic decisions. Systematic concepts will continue to be vulnerable to change as investigations continue to resolve relationships, methodological approaches evolve, and theoretical principles underlying classifications are developed. However, the generic or systematic concepts adopted have no bearing on the actual inventory of moss species diversity. Our list provides a significant update to the previous one by Anderson et al. (1990). This list recognizes an additional 183 species and infraspecific taxa, an additional 54 genera, and an additional 28 families. For all additions, deletions, or synonymies we provide documentation in the form of footnotes. We have not reprinted the synonymy of previous lists but are only including names in the list of synonyms that differ from previous lists. All authority names have been checked and updated as needed. The supra-generic classification is built on that proposed by Goffinet et al. (2009a,b), and integrates proposals by Liu et al. (2019), Bechteler et al. (2023), Li et al. (2024) and many others as referenced in the footnotes throughout the classification. The list of taxa occurring in the United States and Canada is available as a spreadsheet ( Supplementary Table S1 (Buck_and_Goffinet_Suppl_Tables_S1_to_S4.xlsx)), along with an alphabetical list of families of North American mosses and their generic inclusions ( Supplementary Table S2 (Buck_and_Goffinet_Suppl_Tables_S1_to_S4.xlsx)), an alphabetical list of families of North American mosses and their ordinal affiliations ( Supplementary Table S3 (Buck_and_Goffinet_Suppl_Tables_S1_to_S4.xlsx)), and an alphabetical list of orders of North American mosses and their familial inclusions ( Supplementary Table S4 (Buck_and_Goffinet_Suppl_Tables_S1_to_S4.xlsx)).

Acknowledgments
We hesitantly thank colleagues because we seldom completely followed their suggestions! Nevertheless, we are grateful for their ideas and collaboration. Initially, Bruce Allen was going to work on this project but decided to withdraw because he would have had to make too many compromises. You can still see his influence throughout this checklist. Lars Hedenäs offered suggestions for the Amblystegiaceae s.l. We hope he won't be too disappointed that we were more conservative in recognition of genera. Jon Shaw gave us his suggestions for the Sphagnum list. Jim Shevock read over the list to help make sure we didn't omit any taxa recently reported for North America, most of which are from the West. We made abundant use of TROPICOS and bryonames.org (Brinda & Atwood 2024), both for nomenclature and for tracking down references. We appreciate the comments sent to us by John Atwood, John Brinda, María Cano, Vladimir Fedosov, Joe Rohrer, Dale Vitt and Richard Zander. The review by David Toren helped us to avoid missing recent North American additions. We apologize to those we may have contacted but have forgotten; this project has gone on for way too long.

Notes
[1] 1 The Andreaeobryophytina were erected by Goffinet et al. (2009a), but recent phylogenetic evidence (Bechteler et al. 2024, Liu et al. 2019) supports that this lineage is sister to the Andreaeopsida, and this combined monophyletic lineage is best treated as the Andreaeophytina.
[4] 4 The Rhizogemmaceae were erected by Bonfim Santos et al. (in Fedosov et al. 2023b), and resolved as sister to a clade comprising Archidiales, Seligeriales, Grimmiales and Dicranales. We propose to accommodate this family in its own order, Rhizogemmales W.R.Buck & Goffinet comb. et stat. nov. ≡ Rhizogemmaceae Bonfim Santos, Siebel & Fedosov, Plants 12: 1360 [13]. 2023.
[18] 18 The generic circumscription of the Anomodontaceae was revised by Ignatov et al. (2019a) based on phylogenetic inferences from organellar loci. We accept the recognition of Pseudanomodon and Anomodontella but not the segregate unispecific genus Anomodontopsis, and maintain the merger of Haplohymenium with Anomodon (Granzow-de la Cerda 1997).
[20] 20 Anomodon longifolius and A. thraustus were reported as new to North America by Granzow-de la Cerda & Düll (2009).
[50] 50 Spence (2014) treated B. algovicum as a synonym of Ptychostomum pendulum; in Bryum the correct name should be B. algovicum as the combination B. pendulum (Hornsch.) Schimp. has earlier homonyms.
[54] 54 Reported as Gemmabryum brassicoides by Spence & Kellman (2015) but accommodated here in Bryum; Bryum brassicoides (J.R.Spence & Kellman) W.R.Buck & Goffinet comb. nov. ≡ Gemmabryum brassicoides J.R.Spence & Kellman, Madroño 62(2):124. 2015.

[62] 62 Spence (2014) recognized Gemmabryum badium, which is considered conspecific with Bryum imbricatulum by Holyoak & Pedersen (2007), which at the species level takes priority.
[67] 67 Described by Spence & Shevock (2012) as Ptychostomum pacificum; accommodated here in Bryum, under the new combination Bryum pacificum (J.R.Spence & Shevock) W.R.Buck & Goffinet comb. nov. ≡ Ptychostomum pacificum J.R.Spence & Shevock, Madroño59(3): 156. 2012.

R. Shevock et al. 24830 (holotype, cas; isotypes, mo, ny).
[72] 72 Described as Gemmabryum vinosum by Spence & Kellman (2015) and accommodated here in Bryum under the new combination Bryum vinosum (J.R.Spence & Kellman) W.R.Buck & Goffinet comb. nov. ≡ Gemmabryum vinosum J.R.Spence & Kellman, Madroño62(2):127. 2015.

Shevock et al. 32676 (holotype, CAS; isotypes, H, KRAM, MO, NY, UC).
[74] 74 Calcidicranella was erected and segregated from Dicranella by Bonfim Santos et al. (Fedosov et al. 2023b) based on phylogenetic evidence.
[75] 75 Callicladium comprised a single species until Kučera et al. (2019) and Schlesak et al. (2018) transferred Hypnum fujiyamae and H. imponens, respectively.
[76] 76 The species was reported from North America by Schofield (2014) as Hypnum fujiyamae (Broth.) Paris.
[77] 77 Ignatova et al. (2021) argued that C. orbicularicordatum falls within the variation of C. cordifolium; we tentatively retain it as distinct until further data are available.
[97] 97 Described as Oxystegus maragniphyllus by Zander & Eckel (2019) and here accommodated in Chionoloma under the new combination Chionoloma maragniphyllum (R.H.Zander & Eckel) W.R.Buck & Goffinet comb. nov. ≡ Oxystegus maragniphyllus R.H.Zander & Eckel, The Bryologist 122(4): 569. 2019. Canada, British Columbia: West Vancouver Island, Ocluelet, 7 May 1969, W.B. Schofield 89947 (holotype, UBC).
[113] 113 According to Huang et al. (2024) and Ignatova & Fedosov (2008) specimens from the West Coast of North America considered to belong to D. viride are most likely populations of D. hakkodense.
[117] 117 Established for Dicranella palustris (Dicks.) Crundw. ex E.F.Warb. by Ochyra et al. (2003).
[127] 127 Dryptodon was recovered as a clade of ambiguous affinities (Hernández-Maqueda et al. 2008, Larraín et al. 2013) and is here treated sensu Ochyra et al. (2003).
[128] 128 This name has been proposed as a synonym of either Grimmia lisae (Hastings & Greven 2007) or G. decipiens (Maier 2010); we propose to retain the name, albeit in Dryptodon, pending clarification.
[146] 146 See Hastings (2008). However, Maier (2010) synonymized this name with G. tergestina, but more recently it has been recognized by California botanists (Toren 2015; Rae 2021; McLaughlin 2024).
[148] 148 Pending further studies, we follow Redfearn (1991), Arts (1998) and Allen (2002), versus Zander (2007b), who argued for retaining the name G. orcuttii E.B.Bartram for the North American populations.
[152] 152 The species may be present in North America based on herbarium records (Gbif 2024b) although it has not formally been reported from North America.
[154] 154 Reported from the southwestern and south-central United States by Allen (2010); see Gbif.org (2024c).
[160] 160 Hygroamblystegium is, albeit not robustly, resolved as a sister group to Amblystegium (Vanderpoorten et al. (2002), which holds a single species. The two could be merged into a single genus, as adopted by Anderson et al. (1990).
[165] 165 Zander & Hedderson (2016) segregated North American and other species of Hymenostylium in their new genus Ardeuma. However, the phylogenetic study by Cano et al. (2022) highlighted ambiguous monophyly of this and other related genera, and hence we prefer to retain a conservative, i.e., broader, circumscription of Hymenostylium. Hodgetts et al. (2020) rejected recognizing Ardeuma on the basis of unpublished data, which may be forthcoming.
[181] 181 Described as Pseudoleskea tribulosa by Shevock & Buck (2009) and accommodated in Lescuraea under the new combination Lescuraea tribulosa (Shevock & W.R.Buck) W.R.Buck & Goffinet comb. nov. ≡ Pseudoleskea tribulosa Shevock & W.R.Buck, The Bryologist 112(1): 184. 2009. U.S.A., California, Mariposa Co.: Yosemite National Park, Hoffmann Creek watershed S of Mt. Hoffmann and N of Tioga Road, 37°49′52″N, 119°30′50″W, 4 Aug. 2006, J.R. Shevock et al. 28987 (holotype, CAS; isotypes, DUKE, H, MO, NY, UC, US, YM).
[182] 182 Previously this taxon was known as L. brachypus var. andrewsianus Crum & Anderson (Stech et al. 2011).
[184] 184 Based on a collection, D. H. Vitt 24 (MO) from Idaho; but see Vigalondo et al. (2020) who considered this taxon a form of L. affinis.
[229] 229 Newly reported from North America based on a collection, A.J. Shaw 8153, on 14 Sep. 1996, from North Carolina (DUKE, NY).
[252] 252 Considered conspecific with P. nutans by Shaw (2014) but retained as distinct by Hodgetts et al. (2020).
[256] 256 Considered a variety of P. commune by Merrill (2007) but a distinct species by Kariyawasam (2021).
[268] 268 Pterygoneurum ×kieneri (Habeeb) W.R.Buck & Goffinet comb. et stat. nov. ≡ P. subsessile var. kieneri Habeeb, Rhodora 51: 128. 1949. U.S.A., Nebraska, Chase Co.: 8 mi W of Champion, 31 Jul. 1941, W. Kiener 10627 p.p. (NEB). See Guerra et al. (1994), who demonstrated that this taxon is a hybrid between P. ovatum and Phascum cuspidatum. Recognizing this taxon at the species level is treating it like the intergeneric hybrid Entosthodon ×hungaricus (Boros) Loeske (Beike et al. 2014; Patel et al. 2023). This may be the same taxon as P. ×kozlovii, but is recognized until additional data are available.
[275] 275 Described as Brotherella canadensis by Schofield (2006) and accommodated in Pylaidiadelpha under the new combination Pylaidiadelpha canadensis (W.B.Schofield) W.R.Buck & Goffinet comb. nov. ≡ Brotherella canadensis W.B.Schofield, J. Hattori Bot. Lab. 100: 355. 2006. Canada, British Columbia: just NE of Webster Island, Effingham Inlet, Barclayl Cound, Vancouver Island, 49°05′N, 125°09′W, W.B. Schofield 43474 (holotype, UBC).
[296] 296 Treated as conspecific with Schistidium apocarpum by McIntosh (2007) but here resurrected following Ignatova & Blom (2017).
[305] 305 Kuznetsova et al. (2023) recognized the genus Merceya Schimp. to accommodate Merceya ligulata (Spruce) Schimp., but this generic name is superfluous for the earlier Scopelophila (Mitt.) Lindb. (Brinda & Fedosov 2023).
[314] 314 Described by Ando as Hypnum holmenii (Ando 1994) and transferred to Stereodon by Ignatov & Ignatova (2004).
[316] 316 Recognized by Zander (2007a) under Barbula convoluta and accommodated here in Streblotrichum under the new combination Streblotrichum convolutum var. eustegium (Cardot & Thér.) W.R.Buck & Goffinet comb. nov. ≡ Barbula eustegia Cardot & Thér., Bot. Gaz. 30: 17. 1900. U.S.A., Idaho, Latah Co.: Cedar Creek, 1897, L. F. Henderson (holotype, P).
[317] 317 Recognized by Zander (2007a) under Barbula convoluta and accommodated here in Streblotrichum under the new combination Streblotrichum convolutum var. gallinula (R.H.Zander) W.R.Buck & Goffinet comb. nov. ≡ Barbula convoluta Hedw. var. gallinula R.H.Zander, Phytologia 44(4): 195. 1979. Canada, Northwest Territories, Distr. Mackenzie: Nananni National Park, South Nahanni River, Virginia Falls, 61°38′N, 125°42′W, 3 Sep. 1974, G. Scotter 22433 (holotype, NY; isotype, BUF).
[320] 320 The species was resolved as sister to a species of Streptopogon Wilson ex Mitt. in Jáuregui-Lazo et al. (2023) consistent with inferences by Gallego et al. (2022). However, in both cases Streptopogon is nested within a larger Syntrichia clade. We therefore retain amphidiacea within Syntrichia rather than accepting its transfer to Streptopogon, pending further systematic resolution of the complex. However, Kramer (2023) argued for its exclusion from Syntrichia and for its recognition within Tortula on morphological grounds.
[326] 326 Described as T. alleni but corrected orthographically because the species was named for two Allens (Austin 1880): “It gives me great pleasure to be able to dedicate so fine a species to the Allens, father and son.”
[328] 328 For justification for placement in Amblystegiaceae versus Brachytheciaceae see Hedenäs et al. (2020) and references therein.
[345] 345 Based on western North American (Alaska, British Columbia and Washington) specimens held in NY annotated as such by R. Caparrós in 2012.
[346] 346 The occurrence of this species, originally described from Japan, was considered doubtful by Vitt (2014), although he acknowledged that it may be present. Hence, we prefer to retain it for now.
[352] 352 Phylogenetic inferences resolve Voitia within Tetraplodon (Lewis et al. 2014; 2017); Voitia being an earlier name (Hornschuch 1818), Tetrapodon (Bruch & Schimper 1844) is considered a synonym.
[353] 353 Voitia angustata (Hedw.) W.R.Buck & Goffinet comb. nov. ≡ Splachnum angustatum Hedw., Sp. Musc. Frond. 51–52. 1801. Holotype, G00040316.
[354] 354 Voitia mnioides (Hedw.) W.R.Buck & Goffinet comb. nov. ≡ Splachnum mnioides Hedw., Sp. Musc. Frond. 51. 1801. Holotype, G00040318.
[355] 355 Voitia pallida (I.Hagen) W.R.Buck & Goffinet comb. nov. ≡ Tetraplodon pallidus I.Hagen, Kongel. Norske Vidensk. Selsk. Skr. (Trondheim) 1893:75–76. 1894. Norway and Sweden, I. Hagen (s).
[356] 356 Voitia paradoxa (R.Br.) W.R.Buck & Goffinet comb. nov. ≡ Splachnum paradoxum R.Br., Chlor. Melvill. 44–45. 1823. Canada: inter Fort Enterprise et mare arcticum, D. Richardson (bm).
[357] 357 Voitia urceolata (Hedw.) W.R.Buck & Goffinet comb. nov. ≡ Splachnum urceolatum Hedw., Sp. Musc. Frond. 52. 1801. Holotype, G00040320.
[358] 358 Previously treated as Loeskypnum badium (Anderson et al. 1990; Hedenäs 2014a) and here accommodated within Warnstorfia under the new combination Warnstorfia badia (Hartm.) W.R.Buck & Goffinet comb. nov. ≡ Hypnum badium Hartm., Handb. Skan. Fl. (ed. 5) 332. 1849. Sweden: Hn. Lul. lpm. Ananas, 23 Jun. 1848, C.J. Hartman (holotype, ups).
[360] 360 Previously treated as Straminergon straminea (Dicks. ex Brid.) Hedenäs (Hedenäs 2014a) and here accommodated within Warnstorfia under the new combination Warnstorfia straminea (Dicks. ex Brid.) W.R.Buck & Goffinet comb. nov. ≡ Hypnum stramineum Dicks. ex Brid., Muscol. Recent. 2(2): 172. 1801. ‘3, stramineum’ on a sheet with ‘Hypnum’ species in herb. Dickson (holotype, bm).
[361] 361 Previously recognized as Calliergon stramineum var. patens (Lindb.)

W.R.Buck & Goffinet comb. nov. ≡ Amblystegium stramineum var. patens Lindb., Musci Scand. 34. 1879. Finland: Helsingfors, S.O. Lindberg (holotype, h).
[362] 362 Previously treated as Loeskypnum wickesiae (Anderson et al. 1990; Hedenäs 2014a) and here accommodated within Warnstorfia under the combination Warnstorfia wickesiae (Grout) W.R.Buck & Goffinet comb. nov. ≡ Calliergon wickesiae Grout, Moss Fl. N. Amer. 1(4): 250. 1939. Canada, Labrador, 1938, Wickes (holotype, duke).
[376] 376 See Ochyra (1989) for synonymy as Pseudoleskea chilensis (Lor.) Ochyra = Hygroamblyamblystegium varium.
[390] 390 The species was reported from the United States by Weber et al. (2003) but then considered conspecific with G. ovalis by Muñoz (1999).
[391] 391 See Muñoz & Pando (2000). Note that Maier (2010) placed this var. in synonymy with G. elongata.
