Eutypa-like with setae

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

Re : Eutypa-like with setae
Hi Steve,
this does not look like typical Eutypa. Maybe Enchnoa, check Barr (1985) Mycologia 77:549-565, available on Cyberliber.
Cheers,
Jacques

Re : Eutypa-like with setae
Merci bien,
That is very useful, though I am unable to put a name to my fungus from the Mycologia paper. It is at least another kind of ascomycete for my local woodland, with similar spores to Eutypa, but not described in Ellis and Ellis or Fungi of Switzerland. I shall record is as cf. Enchnoa (Barr, 1985).
Cordialement,
Steve
