Hi,

here I have a second indeterminate pyreno which grew on the bark of a living Fraxinus. The ascomata are very conspicuous because they can be from Navicella-like with a small, slit-shaped neck to even Ceratostomella-like with a long and thin neck (I checked that they really are of the same species). The spores are 22,5-25 x 8-9 µm, mature always 4-celled and slightly rough, often with two paler end-cells. The asci are bitunicate and 8-spored. I didn't find a species within the Lophiostomataceae which would fit with my species.

Best wishes and many thanks,

Gernot
