Pyrenopeziza?? Mollisia??
hannie wijers, 27-05-2018 17:36
Hello,

A friend found these small slices on a twig of Rubus. They look like Pyrenopeziza or Mollisia. However, the spores do not match with this. The size of the tracks is 9 - 11 x 3 ?m. The size of the asci is 44 - 57 x 4 ?m. Asci J + with Baralse. The parsfysen are bud form with a drop in the top. We also thought of Micropeziza but are absolute not sure. Does anyone have an idea for us that we can continue with?
Greetings
Hannie

Re : Pyrenopeziza?? Mollisia??
This is difficult in the dead state.  But from apo shape I am reminded of Pyrenopeziza petiolaris. It cannot be an Acer petiole? The spores look quite banal for Mollisia and Pyrenopeziza.

Hallo Hans Otto, 

I'll ask her again. This afternoon she told me it was Rubus. Thank you anyway

Re : Pyrenopeziza?? Mollisia??
No I don't. I could perhaps if I saw the fungus from photos in living state.

I'll ask her if she has a foto of the twig. Thanks again.

Re : Pyrenopeziza?? Mollisia??
Of course it is too thick for a petiole, and the angular cross section tells indeed for Rubus.
In the literature P. petiolaris occurs not only on petioles of different trees but sometimes also on herbaceous stems. But mostly it is on Acer leaves.
