I found these frb on the twig of Rubus. Ik took a look at the site of Bjorn and saw a couple of Gnomonia's. Could these also be the same?
The measure if the spores are 5-7-9-10 x 2-3 µm. 

Thank you
Hannie

Re : on Rubus
Dear Hannie,
I don't think that the things you call spores are really the ascospores of the fungus.
The macroscopy fits well with the genus Gnomonia but not microscopical features.  
For example, you can find  a view of Gnomonia rubi there : http://www.ascofrance.fr/search_recolte/2072

Re : on Rubus
Hello Alain,


you'r right. They don't look right. Maybe later these week I can find a new one and otherwise I throw it away. Thank you anyway.
