Atwood, J., WR. Buck & B. Goffinet. 2025. Bryomyces, a genus described from foliar moss gemmae, is an earlier name for Plenogemma (Orthotrichaceae). Novon 33: 115–121.
Abstract reads: Bryomyces Miq. and Phragmidiolum Müll. 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 Plášek, 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 Müll. Hal., and Ulota phyllantha Brid. [≡ Plenogemma phyllantha (Brid.) Sawicki, Plášek & 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 Müll. Hal., and Phragmidiolum sparsum Müll. Hal. are new synonyms of Orthotrichum lyellii Hook. & Taylor [≡ Pulvigera lyellii (Hook. & Taylor) Plášek, Sawicki & Ochyra]. Lectotypes are designated for B. montagneanus, Phragmidiolum, Phragmidiolum apicale, and Phragmidiolum ramosum, while a neotype is designated for B. elegans.
