Discomycet on leaves of Acer pseudoplatanus

Gernot Friebes, 06-10-2009 22:05

Hi,

I found the following discomycet on old, wet leaves of Acer pseudoplatanus (5.9.2009). I do not know why but I do not even come to a proper genus (the best genus I came across was Microscypha).
The apothecia were quite tough with a brown, somewhat appressed-hairy margin. The spores were 19-21 x 5 µm, the asci were 8-spored, IKI bb and without croziers. The paraphyses were up to 3 µm wide without any notably content. The hyphae at the margin were brownish incrustet.

Best wishes and many thanks
Gernot
