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

They develop in telia (sing. telium, or teliosoruses).
The telial host is the primary host in heteroecious rusts. The aecial host is the alternate host (look for pycnidia and aecia). These terms apply when two hosts are required by heteroecious rust fungus to complete their life cycle.
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.
