 Since "Camarophyllopsis" was published earlier than either of these competing names, it has priority.Eef Arnolds proposed an infrageneric classification of "Camarophyllopsis" consisting of two subgenera differentiated by the structure of the cap cuticle (pileipellis).Subgenus "Camarophyllis" contained species with a trichodermium pileipellis (with hyphae arranged perpendicularly to the cap surface), while species in subgenus "Hygrotrama" had a hymeniderm pileipellis (with a structure similar to that of the hymenium).
