I do have one more "burden of the past" where I don't get to an identification and hope for your help.

Description: Apothecia dark, hymenial disc almost black, up to about 0.7 mm in diameter. Margin distinct, raised somewhat above hymenium. Margin and Excipulum brown. Hymenium very densely agglutinated, gelatinous. Brown epihymenial matter. Spores are 15-18 x 4-5 µm, brown, smooth(?), two-celled, somewhat thick-walled. Subhymenium brown. Excipulum with mostly globose to ellipsoid or sometimes nearly rectangular cells, mostly hyaline to somewhat brownish. Margin distinct in microscopic composition from Excipulum and Hymenium, very gelatinous, with very indistinct prolonged elements (see photo).

Substrate: Decorticated deciduous wood, most probably Alnus or Corylus

To me it resembles some lichens with its margin, but I recognize no thallus.

Any help is welcome

Re : marginate apothecia

Dactylospora? Gib mal IKI zu.

Re : marginate apothecia

Da wäre ich jetzt nicht sicher, ob das Jod überhaupt an den Asci ankam. In Dactylospora sollten die Asci auch in Melzer sehr stark blauen.

Re : marginate apothecia

Probably D. stygia var. stygia ?
Zotto knows it very well and will be ok after iodine reaction, I suppose.

Re : marginate apothecia

Yes, but the yellow iodine should be visible on the photo (plasma staining), otherwise I cannot believe :-)
If yours is rather thin, please try directly in a drop of MLZ.
