DescriptionA fungus with gelatinous poroid fruiting bodies was found in Puerto Rico and determined by macro- and micromorphology to be most similar to members of the lamellate agaric genus Resupinatus. This species is described as a new species, Resupinatus porosus. Phylogenetic analyses of ribosomal DNA sequences support the inclusion of this fungus in the clade containing Resupinatus, and indicate that this monophyletic group also includes members of Asterotus and the cyphelloid genus Stigmatolemma. Resupinatus porosus is another example of tropical poroid representatives of lamellate agaric genera. Resupinatus is emended to include species with poroid (R. porosus) or merulioid (R. merulioides) hymenophore as well as those with laterally stipitate (Asterotus) or cyphelloid (Stigmatolemma) fruiting bodies. Seven new combinations in Resupinatus are proposed to accommodate well-known species of Stigmatolemma.
