Amphibian chytridiomycosis, a disease affecting amphibians, especially frogs, caused by the fungus Batrachochytrium dendrobatidis, known as the amphibian chytrid or simply Bd. The production of asexual and sexual spores at different times during the life cycle of a fungus is of selective value, with asexual reproduction normally occurring at optimal conditions and sexual reproduction occurring when conditions are less favorable.

Zoospores are attracted to the host cell by specific signals. Sexual reproduction. Molecular studies now firmly place the Chytridiomycota within the fungal kingdom. Zoospores. Asexual reproduction occurs through the release of zoospores (presumably) derived through mitosis. The thalli of these fungi are typically microscopic and varied. Asexual Life Cycle. Introduction.
