Abstract: New phylogenetic studies focused on the family Sarcosomataceae support the independence of the genera Plectania, Pseudoplectania, Donadinia, Sarcosoma, Galiella and Urnula. Galiella is restricted to the temperate species, while the tropical taxa seem to be more related to the family Chorioactidaceae, and are here accomodated in the prioritary genus Trichaleurina. The lineage including the type species of Urnula is here shown to include also several morphologically deviant species. The genus Pseudosarcosoma is here proposed to accommodate Sarcosoma latahensis/Plectania latahense in the family Chorioactidaceae, since this lineage is not related to the type species of the genus Sarcosoma, S. globosum
