<unk>  has undergone numerous nomenclature revisions since its first description in 1895. It formerly contained two varieties:<unk>  var.<unk>  and<unk>  var. grubii. A third variety,<unk>  var. gattii, was later defined as a distinct species,<unk>  gattii. The most recent classification system divides these varieties into seven species.<unk>  refers to<unk>  var. grubii. A new species name,<unk>  deneoformans, is used for the former<unk>  var.<unk> . C. gattii is divided into five species. The teleomorph was first described in 1975 by K.J. Kwon-Chung, who obtained cultures of Filobasidiella<unk>  by crossing strains of the yeast<unk> . She was able to observe basidia similar to those of the genus Filobasidium, hence the name Filobasidiella for the new genus. Following changes to the International Code of Nomenclature for algae, fungi, and plants, the practice of giving different names to teleomorph and anamorph forms of the same fungus was discontinued, meaning that Filobasidiella<unk>  became a synonym of the earlier name<unk> .
