the teliospsores are arragned like basalt columns, on top covered by a layer of a waxy substance. Initially they are one-celled, but in the end meiosis takes place, resulting in a chain of four hapoid cells. Each one germinates under formation of a sterigma, on top of which eventually a spore will be formed (Mims & Richardson).

The uredinia and telia of Coleosporium species morphologically are indistinguishable. For pictures see for instance C. melampyri and C. tussilaginis.
