Notes on Early Land Plants Today. 36. Generic treatment of Lophocoleaceae (Marchantiophyta)

Abstract

Recent molecular phylogenetic studies on Lophocoleaceae have recovered some well-supported monophyletic lineages within Chiloscyphus s. lat. that merit recognition at the generic level. As a consequence, Chiloscyphus is herein circumscribed to include only Chiloscyphus subgen. Chiloscyphus, Chiloscyphus subgen. Connati is elevated to generic rank to which the new name Cryptolophocolea is applied, and Lophocolea, Pachyglossa and Clasmatocolea are recognized as distinct genera. Tetracymbaliella is transferred to the Brevianthaceae, and a synopsis of the genera currently recognized in Lophocoleaceae is provided.
