a Pachyphloeus for sure. I find the key, description and fotos in Montecchi & Sarasini often not fitting collections in a satisfying way. Unfortunately, no modern key seems to be available (?).

Thank you for your comment.
In the book Nordic macromycetes Vol1 Ascomycetes there is a key with 3 species:
P. conglomeratus, P. citrinus and P. melanoxanthus.
P. melanoxanthus comes closest to the description and findings.
Here an atricle about Pachyphloeus melanoxanthus:
