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

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.
