The Telial stage is one of the stages in the life cycle of a parasitic heteroecious fungus. It is discernible by the formation of large teliospores that the fungi produces to overwinter. The telial stage of heteroecious parasitic fungi is spent on the secondary host plant. A primary aecial stage is spent parasitizing a separate host plant which is a precursor in the life cycle of heteroecious fungi. Spores are released from the telia in the spring. The spores can spread many kilometers through the air, however most are spread near the host plant (Brand, 2004). ==Host Plants== There are a number of plants that can be infected by the telial stage. Therefore the telial stage is considered a pathogen to those plants. A few specific plant pathogenic species are listed here with their hosts. # ''Puccinia graminis'' or known commonly as black stem rust. It infects many different cereal crops. # ''Gymnosporangium juniperi-virginianae''. It infects the eastern red cedar (Volk, 1999). This is shown to the right. # ''Gymnosporangium sabinae''. It infects pear trees. File:Stem rust close up.jpg|''Puccinia graminis'' on wheat.
