In low-income and middle-income countries, C. neoformans is a neglected killer in most parts of the world.Since the basidial shape is similar to that of Filobasidium, F. neoformans was initially thought to belong to the same family as the Filobasidium species (Kwon-Chung 1987). The serotype A strains of the anamorph of F. neoformans have been subclassified as Cryptococcus neoformans var. grubii (Franzot et al. 1999).
