(redirected from chlamydospores)
Also found in: Dictionary, Thesaurus, Medical.


A thick-walled, unicellar resting spore developed from vegetative hyphae in almost all parasitic fungi.



the name for the spores of smut fungi (order Ustilaginales) and certain other fungi, formed from specialized or nonspecialized cells of the hyphae, which become enlarged and usually acquire a thickened, often pigmented membrane. Depending on their numbers, chlamydospores may be solitary or grow in chains. They contain considerable reserves of nutrients. A fungus in its resting state can survive unfavorable environmental conditions by forming chlamydospores.
