Notes on Clavarioid Fungi. VII. Redefinition of the Clavaria vernalis - C. mucida Complex

Thirteen species of clavarioid lichenoid fungi are grouped into a new genus, Multiclavula, emphasizing hyphal morphology as a unifying characteristic. Included are M. sharpii n. sp., one species formerly placed in Clavaria, seven from Clavulinopsis and four from Lentaria. Of these species, only M. constans is free-living: the others are associated with algae, mosses, or allegedly associated with a slime mold. The type species of the genus is designated as M. corynoides (Pk.) Pet. (Clavaria corynoides Peck). Keys, descriptions and illustrations of basidial and spore details are given.
