Discostroma on Rubus idaeus
Björn Wergen,
24-05-2013 18:09

here is another pyrenomycete growing on Rubus idaeus stems with small, black perithecia, embedded into the surface and covered with clypeus-like structures (Clypeus?). Perithecia are characteristicly amber coloured inside, as I have seen it in species of Discostroma.
The species has 3septate spores of 12-15x4-4,5µm size, hyalin, smooth. Asci uniseriate, unitunicate, IKI- (or very very weak +).
I have tried keys for Discostroma but had no success with it, as I came to "D. callistemonis", which has a different substrate :(
Thanks in advance!
All the best
