Coleosporium asterisci-aquatici

Coleosporium asterisci-aquatici (Saccardo) Sydow & Sydow, 1921

on Pinus?



spermogonia, aecia

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).

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

uredinia, telia

Asteraceae, narrowly oligophagous

Asteriscus aquaticus; Pallenis maritimus.

Possibly also Asteriscus imbricatus; Pallenis spinosa.


Coleosporium tussilaginis f. sp. inulae Helfer, 2013; Uredo asterisci-aquatici (Saccardo) Gjaerum, 1990.
