The generic name Dorcadion Adans. ex Lindb. is a superfluous and illegitimate name for Orthotrichum Hedw. The new generic name Dorcadionella Plášek, Sawicki & Ochyra is proposed for a segregate of Orthotrichum which comprises species with superficial stomata that are always monoicous and only occasionally produce gemmae on leaves. Dorcadionella affinis (Schrad. ex Brid.) Plášek, Sawicki & Ochyra is selected as a type of this new generic name. The genus Dorcadionella consists of 63 species and one variety that have a worldwide distribution. Traditionally, they were all placed in Orthotrichum and the relevant transfers to the new genus are effected in the present account.

Are Orthotrichum and Dorcadion (Orthotrichaceae, Bryophyta) heterotypic generic names?
