Cryptococcus gattii, formerly known as Cryptococcus neoformans var. gattii, is an encapsulated yeast found primarily in tropical and subtropical climates. Its teleomorph is Filobasidiella bacillispora , a filamentous fungus belonging to the class Tremellomycetes .
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. [6] C. neoformans refers to C. neoformans var. grubii. A new species name, Cryptococcus deneoformans, is used for the former C. neoformans var. neoformans.
Cryptococcus is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species. The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella , while Cryptococcus was reserved for the yeasts.
The majority of Cryptococcus species live in the soil and do not cause disease in humans. Cryptococcus neoformans is the major human and animal pathogen. Papiliotrema laurentii and Naganishia albida, both formerly referred to Cryptococcus, have been known to occasionally cause moderate-to-severe disease in human patients with compromised immunity.
Cultured colonies are cream to pale pink, the majority smooth with a mucoid appearance. Some are rough and wrinkled, but this is a rare occurrence. [3] Naganishia albida is very similar to Cryptococcus neoformans, but can be differentiated because it is phenol oxidase-negative, and, when grown on Niger or birdseed agar, C. neoformans produces melanin, causing the cells to become brown, while N ...
Solicoccozyma terrea (synonym Cryptococcus terreus) is a species of fungus in the family Piskurozymaceae. It is only known from its yeast state. In this state, it can use glucose, lactose, galactose and potassium nitrate. The cells are oval with mucous capsules. Cultures of the yeast are cream at first, becoming tan with a “tough” surface skin.

Papiliotrema laurentii (synonym Cryptococcus laurentii) is a species of fungus in the family Rhynchogastremaceae.It is typically isolated in its yeast state.. In its yeast state, it is a rare human pathogen, able to provoke a skin condition, [1] or fungemia in immunocompromised hosts.
