Today I had this little black spot under the mic. The spores are septed 3 times, The measure of the spores are 14-16x 6-7 µm in water. I couldn't find a whole ascus, Maybe some older material Anyway I'm still curious wht it could be. I wonder if it could be a hysterium. Can anyone send me to the right direction. Thanks a lot.

Greetings
Hannie

Re : On Rubus
Hi Hannie,

this reminds me on Camarosporium rubicolum, not rare on dead Rubus stems. It is an anamorphic state of a botryosphaeriales species.

björn

Re : On Rubus
sorry, but this is Seimatosporium (Sporocadus) lichenicola, the anamorph of Discostroma corticola, according to Sutton (1980).
Best regards, Walter
