I have examined the collection and found the spores (at least some) to have longitudinal striations, which indicates Ascotremella faginea.

According to Hans-Otto Baral’s study of the type collection (unpublished), it appears Neobulgaria pura var. foliacea is not a good taxon. At least part of that collection is A.f.

Thus, he considers Swiss-Vol-1 #165 to accurately represent A.f. except in indicating J- for the iodine reaction. The ring apparatus of A.f. does stain blue, but it is such a small structure that the reaction can be hard to see (as are the fine striations on the spores). #164 probably also is A.f.

to “Fungi of Switzerland”, quite a few here:

say that their “Neobulgaria pura var foliacea”, is possibly Ascotremella faginea. And that’s what this looks like to me..
