Wils. in Spruce. The record of Philonotis muehlenbergii from Hancock County (Patterson 1930), has been redetermined as P. fontana (Zales 1973). The record of Bryum muehlenbeckii from Oxford County (Parlin 1939) is based upon a misdetermination of Bryum pseudotriquetrum. The record of Pohlia proligera from Cumberland County (Pitman 1930), actually represents P. annotina. Mielichhoferia mielichhoferiana is excluded from the Maine moss flora. The nomenclature and taxonomic concepts of the species in this list follow Anderson et al. (1990) with the exception of Sphagnum which follows Anderson (1990). Unless otherwise noted these collections are deposited at MO. Collections made by B. Allen are listed only by collection number.
Six mosses, Bryum ambylodon, Calliergon richardsonii, Grimmia hartmanii, G. hermanii, Hygrohypnum subeugyrium, and Orthotrichum pusillum are reported for the first time from the state of Maine. Previous reports of Brynia graminicolor from Cumberland county, Bryum muehlenbeckii from Knox county, Bryum cirrhatum from Oxford county, Climacium americanum from Hancock county, all reports of Dicranum groenlandicum and Trematodon longicollis from Oxford county are based on misdetermined specimens. Many of the collections reported below were obtained on loan from the University of Maine Herbarium (MAINE). This herbarium, though small, has many historical Maine moss collections made by Elmer Drew Merrill, John C. Parlin, Rachel Lowe and Elizabeth Dunham or reported by Parlin (1939) in his work on Maine mosses. The collection is being systematically loaned (one or two families at a time) to me for examination and annotation. Unless otherwise noted all collections cited are deposited at MO. The localities for collections made by B. Allen, which are cited in the list only by collection number, are given below.
John Parlin and his associates. Many of Parlin's mosses were identified or verified by Robert Williams, and it is this set of Parlin's collections that is preserved in NY. Nearly all the mosses listed below are either new or newly verified Maine county records. A few literature reports of Maine mosses have, upon re-examination, been found to be based on misdeterminations. These are noted below. There are 3 mosses in this paper that did not appear in the Conspectus Maine Mosses (Allen 1995): Bryum uliginosum (Brid.) Bruch & Schimp. in B.S.G., Dicranum condensatum Hedw., and Timmia megapolitana Hedw. At the same time 4 mosses have been provisionally deleted from the Maine moss flora: Leucodon julaceus (Hedw.) Sull., Dicranum muehlenbeckii Bruch & Schimp. in B.S.G., Pohlia elongata Hedw. var. humilis (Schimp.) Amann, and Hygrohypnum micans. (Hedw.) Broth. As a result, the number of mosses reported from Maine is now 391 taxa. The nomenclature and taxonomic concepts of the species in this list follow Anderson et al. (1990) with the exception of Sphagnum which follows Anderson (1990).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
