A thick-walled, dikaryotic, often overwintering spore of most rust and smut fungi, which germinates to form a basidium.


(Botany) any of the dark noninfective spores that are produced in each telium of the rust fungi and remain dormant during the winter. Also called: teleutospore
[C20: from telium + spore]


(ˈti li əˌspɔr, -ˌspoʊr, ˈtɛl i-)

a thick spore that develops in the telium of a rust or smut fungus during the fall and germinates the following spring.
[1870–75; telio- (comb. form of telium) + -spore]
