Lasionectria?

I did not arrive with Amy's keys to a proper genus. I admit I did not test KOH but assume it is a Bionectriacee.
Perith. pale orange-rose, ca. 150 µm diam, dry collapsing. Sp. *10-12 x 3.3-3.5 µm, narrowly ellipsoid, 1-septate, upper cell slightly larger?, 1 medium-sized oildrop in each half near septum, smooth.
thanks

Re:Lasionectria?
Hi, Zotto,
your fungus is it fungicolous? or on a byssoid stroma? could you make a section of acomatal wall? could you give the thickness of it?
Thank you

Re:Lasionectria?
Ok Zotto,
I think it is maybe a Nectriopsis but with so not enough material it is going to be difficult to find a name.
Cheers,
Christian

Re:Lasionectria?
Have today looked at another ascoma, I kept the branch moist overnight. So now I have seen abundant mature spores. Also the hairs are frequently apically branched, with truncate ends.
Perith. pale orange-rose, ca. 150-200 µm diam (without hairs), dry collapsing. Asci 8-sp., IKI-. Sp. submature *10-12 x 3.3-3.5 µm, mature *11-14 x 3.7-3.9(-4.5) µm, KOH 11-14 x 3.3-3.6 µm, narrowly ellipsoid, 1-septate, 1 medium-sized oil-drop in each half near septum, distinctly densely warted (punctate), in KOH looking almost smooth (warts lower?). Hairs 35-48 x 3.5-4.5 µm, wall 1-1.5 µm thick, IKI-. The peridial wall is laterally about 25 µm thick, KOH-
