Synonymy, taxonomic notes, and range extensions for several noteworthy Asian liverworts

摘要

Several noteworthy liverworts are reported from China, including Bazzania horridula Schiffn. and Riccardia tamariscina (Steph.) Schiffn. new to China, and five species new to mainland China. Cololejeunea dozyana (Sande Lac.) Schiffn. and Leptolejeuneaudarii M.Dey & D.K.Singh are reported new to Thailand. Chiloscyphus yunnanensis C.Gao & Y.H.Wu, previously known only from the type locality, is proposed to be synonymous with the tropical Asian Chiloscyphus ciliolatus (Nees) J.J.Engel & R.M.Schust. SEMobservations reveal that the wax-like projections on the thallus surface of Riccardia tamariscina do not belong to surface wax. Two types of oil bodies in Bazzania are illustrated. It is suggested avoiding the use of the term ‘Bazzania-type’ when oilbodies are described.
