Teliospore

 

(also teleutospore), one of the types of spores characteristic of rust fungi. Teliospores are mainly wintering spores. They may be unicellular or multicellular, stalked or stalkless, and free or concresced into styles or crusts. Rust fungi are divided into families and genera on the basis of their type of teliospore. The spores of smut fungi are sometimes called teliospores.
