Coleosporium asterisci-aquatici (Saccardo) Sydow & Sydow, 1921
not known; probably:
on Asteriscus, Pallenis
the teliospsores are arranged 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).
Asteraceae, narrowly oligophagous
Possibly also Asteriscus imbricatus; Pallenis spinosa.
Coleosporium tussilaginis f. sp. inulae Helfer, 2013; Uredo asterisci-aquatici (Saccardo) Gjaerum, 1990.
