Hello,I have identified this fungus as Hymenoscyph
Polydesmia sp.

1) probably Polydesmia, but asci with inamyloid pore, and spores nonseptate, otherwise paraphyses propoloid, and if to follow the key of Korf (1978) it may be P. fructicola.
Apothecia pustulate to flat-cupulate, grayish, translucent, up to 400 x 100 mk, hymenium minutely rough, outside and edge appear smooth.
Excipulum textura prismatica, outer hyphae end by ventricose or clavate cells (hairs); asci clavate, clamped, with inamyloid pore, 54 x 7 mk; spores ellipsoid and curved (allantoid), non-septate, with large irregular guttulae, 11,6 (10-13,1) x 3,4 (3,1-3,9) mk; paraphyses irregularly bulged in different parts, branched 2-3 times, curved at the tips.

Re : Polydesmia sp.
Dear Nina
Polydesmia has 3-septate spores and amyloid asci, and these apically curved paraphyses are also untypical of that genus.
Do you have the fungus fresh? Please do photos in water, that would greatly help. Possibly there are guttules in the paraphyses that disappear when mounting in such lethal agent.

Re : Polydesmia sp.
Good photos, but regrettably all in dead state. I assume the fungus was collected some weeks ago and was dried? Then these guttules disappear irreversibly.
I am sorry I have no idea of a genus. My idea was something around Naeviopsis, but I do not believe.
