Teliospore

Teliospore

Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi (rusts and smuts), from which the basidium arises.

Development

They develop in "telia" (sing. "telium", or "teliosoruses").

Morphology

Teliospores are usually dark-coloured, and consist of two dikaryote cells. As the spores germinate, the nuclei undergo karyogamy and thereafter meiosis, giving rise to four-celled basidia with haploid basidiospores.

They also have a thick-capped telia as compared to urediniospores.
