Cryptococcus neoformans and Cryptococcus gattii are closely related basidiomycetous fungi that commonly infect humans to predominantly cause meningoencephalitis. Both grow as budding yeasts in the environment and in the infected host yet undergo a dimorphic transition to a filamentous monokaryon or dikaryon during sexual reproduction.

Cryptococcus neoformans and Cryptococcus gattii are the two etiologic agents of cryptococcosis. They belong to the phylum Basidiomycota and can be readily distinguished from other pathogenic yeasts such as Candida by the presence of a polysaccharide capsule, formation of melanin, and urease activity, which all function as virulence determinants.
