We inventoried bryophytes in Canaan Valley and Blackwater Falls State Resort Parks and in Dolly Sods Wilderness (Monongahela National Forest) during the four-day Crum Workshop. We found a total of 170 species with 140 mosses and 30 liverworts (including collections made before and after the Workshop) on Pottsville sandstone, Greenbrier limestone, and organic substrates in red spruce (Picea rubens)-northern hardwood forests and Sphagnum-dominated fens. About 84% of the species have very broad distributions (63% northern Northern Hemisphere, 21% wide - ranging to the southern Southern Hemisphere), whereas 16% are endemic to the Americas. Five state records include two circumpolar-montane species (Plagiothecium nemorale and Philonotis capillaris), two North American endemics (Brachythecium falcatum and Orthotrichum parvulum), and one globally wide species (Campylopus flexuosus). This was the second Appalachian report for the disjunctive, suboceanic, temperate moss C. flexuosus.

There are growing numbers of lichens observed outside their expected distributions. A recent discovery of Xanthoria parietina in Provo, Utah, USA is added to that list. Other individuals of this species have been noted in inland western United States, but this specimen was believed to be the first sighting of X. parietina in the Great Basin. Herbaria records were investigated for distribution data for other collections of X. parietina outside of their typical habitat. The identity of this unexpected lichen occurring in Provo was confirmed via DNA sequencing, and based on herbarium records, was found to be the second known occurrence in the Great Basin. This discovery raises questions regarding human facilitated dispersal and establishment of lichens.

Eight new taxonomic combinations are made for macrolichens that occur in North America. These combinations attempt to improve the practicality of taxonomic revisions resulting from molecular systematics. The new combinations are in the genera Bryoria, Cetraria, Peltigera, Scytinium, and Sulcaria.

The lichenicolous fungus Sphaerellothecium taimyricum is reported as new to North America. The lichenicolous fungus Lichenopeltella leprosulae and the lichen Protothelenella leucothelia are reported as new to the USA and the hepaticolous fungus Pleostigma jungermannicola is reported as new to western North America. Arthonia xanthoparmeliarum is reported as new to northwestern North America and seven other species of lichenicolous fungi are reported as new to the contiguous 48 states of the USA. In total, 18 species are reported new to the state of Washington, 2 to California and Oregon, and one new species is reported for each of three other western states.
