Montane mosses are an important component of the flora in the Gulf of St. Lawrence region, where many species are rare and/or disjunct from the Arctic or the Western Cordillera. This paper presents an annotated list for 44 montane species as documentation for conservation work and future studies. One species, Orthotrichum rupestre, is reported new to the region from Newfoundland. Occurrence in the Gulf region, global distribution, literature references, and conservation status are given for all taxa.
Lichens were collected from Overton Park, an old-growth, urban park in Memphis, TN. The lichen survey was conducted to establish a baseline inventory of lichens present in the most southwestern part of the State of Tennessee. In total, 272 lichen voucher specimens were collected comprising 26 genera and 41 species.
We present a checklist of soil-dwelling bryophytes and lichens for the south Puget Sound prairies based on field investigations of seven prairie sites conducted over the period of 2012–2014. We report a total of 32 terrestrial bryophyte taxa including 27 mosses and 5 liverworts, representing 20 families and 27 genera. We report a total of 32 terrestrial lichen taxa, representing three families and three genera. Four lichens, Cladonia novochlorophaea, Cladonia ciliata var. ciliata, Cladonia ciliata var. tenuis and Cladonia portentosa ssp. pacifica are proposed State-listed lichens considered rare by the Washington Natural Heritage Program. We report one additional species that was not listed on the WNHP rare lichen list, but appears to be rare in Washington: Cladonia concinna. We recommend that Cladonia concinna be added to the Washington Natural Heritage list of rare lichens. We did not find any State-listed bryophytes. We did, however, find one non-native moss, Pseudoscleropodium purum, which appears to be introduced to the Puget Sound prairies and one native ephemeral moss, Funaria hygrometrica, that may have been unintentionally outplanted to burned areas of the prairies we surveyed along with greenhouse grown native vascular plant plugs. The species list presented here should provide a starting point for assessing the current and future conservation status of soil-dwelling bryophyte and lichen communities of the south Puget Sound prairies.
Two taxa regarded as varieties of Collema tenax by the monographer Gunnar Degelius are shown to be species with distinct characters, including ecogeography.
(1) Enchylium expansum (Degel.) comb. nov., a widespread, shiny, rather Leptogium- like species, is disjunctly circumpolar with outlying single localities in the European Alps (Austria) and the southern Rockies (USA) at high altitudes (ca.3000m), as well as with an interesting single locality on Kerguelen Island in the Southern Hemisphere. (2) Enchylium substellatum (H. Magn.) comb. nov. has characteristically folded thalli with elongated, narrow lobes as well as notably long and narrow, and constantly 3-septate ascospores. It appears to be most common in the Rockies and Northeast Greenland with single localities in inner China (type) and remarkably in the Sierra Nevada, Spain. It appears to prefer open, clay-rich or sandy soils in more or less continental climates with cold winters and warm summers. They are both referred to the genus Enchylium where the Collema tenax group is now placed.
