Appearance

They are small, fragile, with translucent-striate caps. Caps are more rounded and umbilicate (not conical), the gills are widely spaced and decurrent, and the stipe and cap are punctate-scurfy.

It has nonamyloid smooth, hyaline (translucent) basidiospores and tissues, poorly 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 or in Omphalina or Hydropus. Phylogenetically, Phloeomana is distant from the Mycenaceae and is closest to a clade or group that includes Atheniella.
