Re : Pyrenomycet on Rubus
Hi Maren
I am not even sure what order this is. The apical rings look helotialean, the paraphyses in gel perhaps more ostropalean. Are the ascomata really perithecioid? Did you try a median section with a razor blade?

Re : Pyrenomycet on Rubus
Hi Zotto,
you are right :). I tricked myself, it is not a pyrenomycet but a fungus of the Naevioideae. I put the twig in water and it appeared. Now I'm searching for the genera. It might be Laetinaevia sp. but I didn't find a match so far. I have to check on the textura.
