Abstract
Replacement names are proposed for two later homonyms of Heteronema fusiforme Skvortsov. The combination Poterioochromonas malhamensis (E. G. Pringsh.) D. Kapustin, comb. nov. is validated. The new combination Marchantia quadrata Scop. subsp. hyperborea (R. M. Schust.) Borovich., comb. nov. is published for the Arctic subspecies of the former Preissia quadrata. The lectotype of Scapania subnimbosa Steph. is designated. The name Tritomaria quinquedentata (Huds.) H. Buch var. grandigemma Potemkin, var. nov. is validated.
