[email protected] ABSTRACT This state and county checklist of the species of mosses known for Wyoming includes literature reports, lists of representative specimens examined, taxonomic and floristic annotations, and illustrations from the Flora of North America volumes 27 and 28. The account includes 380 species plus seven varieties. Past checklists of the mosses of the state of Wyoming include those of Nelson (1900), Porter (1937, unpublished dissertation), and Eckel (1996). Additional papers of floristic importance are listed in the Wyoming Mosses Bibliography. A detailed summary of collecting activity and early floristic publications is given by Eckel (1996). Continuing work on the state flora since 1996 by many bryologists and recent changes in classification introduced with the Flora of North America (FNA 2007, 2014) make a new compilation worthwhile. The most recent checklist of Eckel (1996) included 290 species plus 25 varieties, while the present list cites 380 species plus seven varieties. This reflects both new work and less emphasis on infraspecific taxa by authors of treatments in the Flora of North America. The nomenclature follows that of the Flora of North America. Synonyms, largely from that work, are provided to help interpret names on specimens. The entries include a paragraph for nomenclature, another referencing the literature including discussion of geographic distribution largely based on information given by FNA and by Lawton (1971), a third paragraph citing specimens examined by myself, and a fourth with discussion.
