Telial host ligneous (Fagacaceae) for C. quercuum and telial host herbaceous (Scrophulariaceae, a plant family that since been dissembled) for C. coleosporioides (=Peridermium harknessii) (Arthur, 1934) An old yet comprehensive treatment.

Looking for the reference on the protein analysis, it might be that I just got confused somewhere and that is bs…

According to this http://www.eppo.int/...
“a record on P. ponderosa in California is probably not this species).”

C. coleosporoides seems to be considered a separate taxa now and is known from CA? At least it is listed here.


Frankly my head hurts, here are some more links…

This was occurring on a young pine tree. I believe it is a three needle pine.

What pine?

Won’t get us very far, but it would be good to record.
