Mycosphaerella patouillardii o buxicola?
Carmen Echavarri, 24-05-2014 20:24
Hi all
Mycosphaerella on living leaves of Buxus sempervirens, from Navarra (Spain).
The description I have of both (M. patouillardii and M. buxicola) is very similar, and I have not found microphotographs  to compare with mine, so I am not able to determine it correctly.
I'd be grateful of some help
Best regards
Carmen

Re : Mycosphaerella patouillardii o buxicola?
Hi Carmen,

I don't have a lot of experience with this group but if you compare the two species you mentioned on the Mycosphaerella Identification Website* your collection fits better to M. patouillardii:

M. patouillardii: on living leaves, ascospores 25-30 x 3-4 µm.

M. buxicola: on dead leaves, ascospores 17-23 x 2-3 µm.

Maybe that helps...

Best wishes,
Gernot
