WebCryptococcus sexual cycles. Cryptococcal cells of a single mating type can undergo unisexual reproduction mainly through endoduplication to generate monokaryotic hyphae. The clamp connections formed during unisexual reproduction are unfused. Sporogenesis occurs in basidia through repeated mitosis and budding following one round meiosis. 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.
