Hymenoscyphus on Rubus
Wim de Groot, 13-09-2025 14:10
We found this hymenoscyphus on rubus fruticulosis. Two large oildrops in the spores (17,5 x 5,0 µm). My only literature is Breitenbach I and this was not helpfull.

Re : Hymenoscyphus on Rubus
With Breitenbach you will be lost in many cases. I guess this is H. macroguttatus because of the large LBs and almost symmetrical spores (not scutuoid as in H. scutula).

Re : Hymenoscyphus on Rubus
Many thanks for your help. What is a better source for Hymenoscyphus?
