The genus Calobryum Nees 1836 belongs to the family Calobryaceae of the order Calotryales (Campbell, 1920) and is characterized by having a fleshy, rhizome-like basal portion, having three-ranked leaves, radially placed on erect stems, and lacking rhizoids. A change in nomenclature, combining Calobryum with the monotypic genus Haplomitrium 1833 of the Haplomitriaceae and of the same order, was suggested by Schuster, based on the opinion that very little generic difference exists between them. This suggestion was supported by a group of hepaticologists: Fulford, Hattori, Inoue and Grolle who, the last named, transferred the species of Calobryum under HaPlomitrium. |
