Bryomyces, a Genus Described from Foliar Moss Gemmae, is an Earlier Name for Plenogemma (Orthotrichaceae)

Bryomyces Miq. and Phragmidiolum M & uuml;ll. Hal., originally described as genera of endophytic bryophilous ascomycetes, refer instead to foliar moss gemmae based on a comparative assessment of their published illustrations with bryophyte specimens and relevant bryological literature. Phragmidiolum and Plenogemma Pl & aacute;& scaron;ek, Sawicki & Ochyra are morphologically congeneric with Bryomyces, the latter of which has priority. The new combination B. phyllanthus (Brid.) J. J. Atwood, W. R. Buck & Goffinet is proposed. Bryomyces elegans Miq., Phragmidiolum apicale M & uuml;ll. Hal., and Ulota phyllantha Brid. [= Plenogemma phyllantha (Brid.) Sawicki, Pl & aacute;& scaron;ek & Ochyra] are new synonyms of that species. Bryomyces montagneanus Miq. is a new synonym of Calymperes androgynum Mont. [= Syrrhopodon rigidus Hook. & Grev.], whereas B. muelleri Miq., Phragmidiolum ramosum M & uuml;ll. Hal., and Phragmidiolum sparsum M & uuml;ll. Hal. are new synonyms of Orthotrichum lyellii Hook. & Taylor [= Pulvig era lyellii (Hook. & Taylor) Pl & aacute;& scaron;ek, Sawicki & Ochyra]. Lectotypes are designated for B. montagneanus, Phrag midiolum, Phragmidiolum apicale, and Phragmidiolum ramosum, while a neotype is designated for B. elegans.
