ABSTRACT: Gymnopus setulosus, described from Jamaica, is now known from the Caribbean, Central and tropical South America. Apparently, Lentinus pilosus Rick, described from southern Brazil, is a synonym. The species belongs in Xerula sect. Xerula, and a new combination is proposed to accommodate this placement. Xerula hispida, described from Costa Rica, appears to be a 2-spored state of X. setulosa, and is reported here from northern South America for the first time.
