Bonjour,
Ce'st petit asco - ce'st trop difficle pour moi. Aidez-mous si'l vous plait!

This asco was sooty black in appearance, just like Chaetosphaerella phaeostroma, and was on a large broadleaf log, upper side. The spores were pale brown en masse, curved, 7-8 x 1.5-2, with 8 pores per ascus. Asci from the embedded perithcia jelly were "bunched" in bundles, and up to 200 um long, with the spore-containing section approx 80 x 10. Most of the micrographs are in Meltzer's and it isn't clear if they are blueing at the apex.
This looks like a Eutypa to me, but the surface is thickly coated in setae, looking like a scouring-pad. The setae are maybe 250  x 10.
Also present in the jelly squash were long winding tubular structures approx 2 wide.
Is this perhaps two fungi growing together? Eutypa and somrthing else?
Mersi bien,
Steve
