this one is especially interesting for me because it is the host of an Unguiculariopsis that I plan to show here soon. First, I would like to know more about hte host. Growing on Quercus (Germany, Baaria), attached twigs at lying middle-aged log. The stromata contain some perithecia with white content (hyaline spores at least for long time). The asci are iodine-negative and bear croziers. There are plenty periphyses. The spores are for a long time hyaline, with the second cell distinctly enlarged, and measurea about 19-23/4-5,5 µm. The pink color in the fotos is from phloxine (mixed with water).
Can somebody help me with the identification?
Best regards, Lothar

Re : pyrenomycete on Quercus
today I re-examined the Unguiculariopsis. It could well be U. robergei which I had before but know that it surely still is a collectiv species.
I would much be interested what the host is - can somebody take a look and give a hint?
Best regards, Lothar
