... found 19.11.23, Schwäbische Alb, on thin dead twig of living Corylus avellana, about 1 m above ground, growing fasciculately.
The spores I measured about 5-8 (10,5)/1,2-1,5 (2) µm, The asci have croziers and are iodine-negative (Barals solution). Some paraphyses (I did not see a lot) wore a brownish deposit as it is described in the publication of Pärtel et al.
In the internet, also on ascofrance, I find some pictures of the species not very much fitting my specimen macroscopically. Is it correctly determined anyway?
Yours, Lothar

Now I think also this fungus is quite similar:
