Summary:The moss genus Taxithelium is reclassified into two subgenera: Taxithelium and Vernieri. The subgenus Vernieri can be distinguished from subgenus Taxithelium by the lanceolate leaves and filamentous pseudoparaphyllia in the former and ovate leaves plus foliose pseudoparaphyllia in the latter. The subgenus Vernieri is revised here and comprises eleven species; one from Africa, two from the Americas, and the remaining from Southeast Asia and Oceania. Keys, illustrations, and descriptions are provided.
