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 haploid 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.

Ranunculaceae, narrowly oligophagous

Pulsatilla alpina, armena, bungeana, halleri & subsp. slavica + styriaca, montana, nigricans, patens, pratensis, regeliana, vernalis, vulgaris & subsp. grandis.
