    • n teleutospore In botany, in the Uredineæ, a thick-walled spore or pseudospore formed by abscission on a branch of the mycelium (sterigma), and on germination producing a promycelium. In some cases the teleutospores are produced early in the season, but usually they appear in autumn, remain in the tissues of the host over winter, and germinate in the spring. See spore, Uredineæ, and cut under Puccinia. Also called brand-spore, pseudospore.
