Additions to and Nomenclatural Changes in the Bryaceae (Bryopsida) in Australia

Abstract

The treatment of the family Bryaceae for Australia is updated based on recent taxonomic studies. Two species of Ptychostomum: P. pallescens (Scheicher ex Schwägr.) J.R.Spence from Tasmania and P. bimum (Schreb.) J.R.Spence from New South Wales, Tasmania and Western Australia are newly recorded. Reported for the first time is the tropical species Gemmabryum erythropilum (M.Fleisch.) J.R.Spence & H.P.Ramsay from northern Queensland. Anomobryum is re-instated in the flora for the species A. auratum (Mitt.) A.Jaeger. Five Australian species of Gemmabryum are transferred to the newly described genus Imbribryum N.Pederson: I. australe (Hampe) J.R.Spence & H.P.Ramsay, I. cheelii (Broth.) J.R.Spence & H.P.Ramsay, I. clavatum (Schimp.) J.R.Spence & H.P.Ramsay, I. crassum (Hook.f. & Wilson) J.R.Spence & H.P.Ramsay, and I. laevigatum (Hook.f. & Wilson) J.R.Spence & H.P.Ramsay. Bryum tuberosum Mohamed & Damanhuri, placed in Rosulabryum by Spence & Ramsay (2006), is transferred to Gemmabryum tuberosum (Mohamed & Damanhuri) J.R.Spence & H.P.Ramsay. New combinations made in studies in North America for Plagiobryoides (replacing Plagiobryum cellulare), Rosulabryum and Gemmabryum are added to bring the flora up to date.
