Our general collecting of bryophytes in the northern Shawangunks, NY (Ulster County) revealed 125 new species records (93 new mosses and 32 new liverworts), which also marks the first published records of liverworts for the area. Incidental to our bryophyte work, we found seven lichen species new to the area. These records combined with prior research makes for a total of 177 mosses (36 families), 36 liverworts (19 families), and 70 lichens (20 families) known from the area. New moss records include the NY State rare mosses Pohlia lescuriana and Coscinodon cribrosus. These additional rare moss species found here, coupled with prior records of new moss habitats and rare species, indicate that the northern Shawangunks is a notable location for cryptogams.
A seemingly undescribed Peltigera and several noteworthy collections were made during a gradient study examining highway effects on forest lichen communities in western Wake County, North Carolina, USA. Rebentischia massalongii is here newly reported from North Carolina. Acrocordia megalospora, Gyalolechia flavorubescens, and Porina scabrida are new records for the Piedmont ecoregion in the state. Lobaria quercizans is noteworthy as belonging to a group of pollution-sensitive cyanolichens that until recently have not been recorded from the Triangle area of central North Carolina. Historical occurrences of Triangle Lobariaceae are also presented.
Orthotrichum lyellii, O. papillosum, and O. pylaisii are reported new to Arizona based on specimens collected in Yavapai County. Orthotrichum lyellii is confirmed for Nevada from three counties along the California border. Orthotrichum papillosum also is confirmed from Nevada from one location near Lake Tahoe. Whether or not O. lyellii (sterile plants with brood-bodies) and O. papillosum (usually fertile plants without brood-bodies) are distinct taxa has been long debated. The occurrence in these out-lying localities in Nevada, where sterile, female plants of O. lyellii are found and fertile plants of O. papillosum occur in different localities, and in Arizona where both taxa occur adds weigh to their distinctiveness. Orthotrichum pylaisii is an uncommon, but widespread arctic-montane species. The Arizona specimen demonstrates a number of clear differences when compared to O. laevigatum and O. rupestre. Whether these western Cordilleran populations should be recognized as distinct from arctic ones in currently unclear.
Significant northern range extensions for Lichinella intermedia and L. americana in the western US are reported. These dwarf cyanolichens are inconspicuous and often overlooked. This paper presents new locations and annotations of previous collections for these rare lichens and for several other more common taxa within Lichinella.
