host plants

Asteraceae, narrowly monophagous

Crepis aurea.


Also described from this host plant is Uredo breventiaca Guyot & Massenot, 1958. However, it has turned out that a mistake has been made with the identification of the host plant; the true host is not known (Klenke & Scholler).


Blumer (1946a), Brandenburger (1985a: 679), Buhr (1964b), Gäumann (1959a), Jage, Scholler & Klenke (2010a), Klenke & Scholler (2015a).
