Cryptococcus dimorphic

WebCryptococcus spp. are dimorphic fungi, but they mainly occur in the yeast form in both the host and the environment, and usually reproduce by budding. Mating produces the perfect (mycelial) stage of the fungus. While there is evidence that both C. neoformans and C. gattii can mate in the natural environment (but not WebColonies usually are visible in 2 to 3 days, but sometimes incubation for up to 10 days is required. Unlike other dimorphic fungi, Cryptococcus grows as a yeast, rather than a mold, on routine fungal media and so is less likely to represent a laboratory hazard than organisms that grow as molds. The organisms form white, creamy colonies.
