Editing Cryptococcus neoformans (section)

==Classification==
''Cryptococcus neoformans'' has undergone numerous nomenclature revisions since its first description in 1895. It formerly contained two [[varieties (biology)|varieties]]: ''C. neoformans ''var.'' neoformans'' and ''C. neoformans '' var.'' grubii''. A third variety, ''C. neoformans ''var.'' gattii'', was later defined as a distinct species, ''[[Cryptococcus gattii]]''. The most recent classification system divides these varieties into seven species.<ref>{{Cite journal|last1=Hagen|first1=Ferry|last2=Khayhan|first2=Kantarawee|last3=Theelen|first3=Bart|last4=Kolecka|first4=Anna|last5=Polacheck|first5=Itzhack|last6=Sionov|first6=Edward|last7=Falk|first7=Rama|last8=Parnmen|first8= Sittiporn|last9=Lumbsch|first9=H.

A new species name, ''Cryptococcus deneoformans'', is used for the former ''C. neoformans ''var.'' neoformans''. ''C. gattii'' is divided into five species.{{citation needed|date=January 2023}}

The teleomorph was first described in 1975 by K.J. Kwon-Chung, who obtained cultures of ''Filobasidiella neoformans'' by crossing strains of the yeast ''C. neoformans''. She was able to observe [[basidia]] similar to those of the genus ''[[Filobasidium]]'', hence the name ''Filobasidiella'' for the new genus.<ref>{{cite journal |doi=10.2307/3758842 |author=Kwon-Chung KJ. |year=1975 |title=A new genus, ''Filobasidiella'', the perfect state of ''Cryptococcus neoformans'' |jstor=3758842 |journal=Mycologia |volume=67 |issue= 6|pages=1197–1200 |pmid=765816}}</ref> 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 neoformans'' became a synonym of the earlier name ''Cryptococcus neoformans''.{{citation needed|date=January 2023}}
