Phloeomana is a bark-inhabiting agaric fungal genus that produces fuscous-colored to whitish mycenoid to omphalinoid fruit bodies in temperate forests. In addition to the type species Phloeomana speirea, 4 other species, P. alba, P. clavata (= M. thujina, M. phaeophylla), P. hiemalis and P. minutula (formerly Mycena olida), have been placed in the genus. The genus is characterized by nonamyloid smooth, hyaline (translucent) basidiospores and tissues, poorly to moderately differentiated cheilocystidia, diverticulate pileipellis hyphae and general smooth stipe hyphae with scattered caulocystidia. It is one of several mushroom genera formerly classified most recently in Mycena, Omphalina, Hydropus, or Marasmiellus. Phylogenetically, Phloeomana is distant from the Mycenaceae and is closest to
