Osculatia – an earlier name for a segregate of Bryum (Bryaceae, Bryophyta)

Abstract

Gemmabryum J.R.Spence & H.P.Ramsay is considered to be congeneric with two monotypic South American moss genera, Neobryum R.S.Williams and Osculatia De Not., of which the latter has priority. It is the earliest available generic name for one of the largest segregates of the broadly conceived genus Bryum Hedw. which consists of some 44 species disposed in three sections that have a worldwide distribution. Traditionally, they were all placed in Bryum or Brachymenium Schwägr. and the relevant transfers to Osculatia are effected in the present account.

Dilutineuron, a new moss genus of the subfamily Racomitrioideae (Grimmiaceae, Bryophyta)

Abstract

Based on available molecular and morphological evidence, the genus Codriophorus P.Beauv. (Grimmiaceae subfam. Racomitrioideae) proved to be a polyphyletic taxon. It consists of two distinct genera which correspond to two sections of Codriophorus, namely sect. Codriophorus and sect. Fascicularia (Bednarek-Ochyra) Bednarek-Ochyra & Ochyra. The latter section is raised to generic rank as Dilutineuron Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek. The new genus consists of the following five species: D. fasciculare (Hedw.) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov., D. brevisetum (Lindb.) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov., D. anomodontoides (Cardot) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov., D. corrugatum (Bednarek-Ochyra) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov. and D. laevigatum (Mitt.) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov.
