Hi to everyone,

I found this small (probably) asco on heavily decayed Polyporaceae (Phellinus punctatus and Inonotus nodulosus most common at this place) on fallen off, rotten branch of Fagus sylvatica. First I thought I found Nectria peziza (since on polypore). However, spores seem too big and too verrucose. Also perithecia seem pyriforme rather than globose and they apparently do not degrade to widely open 'peziza' type cups when old as I expected. Surprisingly I was unable to find asci? In the literature available to me I found no fit to this find.

Would appreciate if somebody could help me by instructing me where to look for further information or how to proceed to come up with an identification? Many thanks in advance.

Place: Zadnjica valley west of Mt. Triglav, East Julian Alps, northwest Slovenia.
Habitat: alpine Fagus sylvatica forest with some Picea abies; in shade, rather cool and humid place; elevation 950 m, average temperature 5 -7 deg C, average precipitations ~ 3.000 mm/year, alpine phytogeographical region.
Spore dimensions: 14.3 [16.5 ; 17.6] 19.8 x 8.6 [10.2 ; 11] 12.6 microns; Q = 1.3 [1.6 ; 1.7] 1.9; N = 24; C = 95%; Me = 17 x 10.6 microns; Qe = 1.6.
I observed also much smaller, numerous (probably) conidia of some kind (Pic.: 8).
