Cryptococcus comprizes two clinically relevant species, Cryptococcus neoformans and Cryptococcus gattii. [49] C. gattii was previously thought to only be found in tropical climates and in immunocompetent persons, but recent findings of C. gattii in regions such as Canada and Western regions of North America have challenged this initial ...
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. Most yeast species formerly referred to Cryptococcus have
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 .

Cryptococcus species (cryptococcus gatti and neoformans) have a polysaccharide capsule surrounding the yeasts to shield the yeast from immune system killing. Cryptococcus also has a cell wall laccase , a copper-containing cell wall enzyme that increases the release of dopamine and prostaglandin E2 inflammatory markers in humans to increase ...
Some species produce filamentous, sexual states with distinctive basidia and are parasites of other fungi. Most, however, are only known from their yeast states. Several species of Cryptococcus are human pathogens.
Species are currently only known from their yeast states, most of which were formerly referred to the genus Cryptococcus. Some 15 species have been described worldwide. [1] Naganishia albida is an occasional human pathogen.
