Hi Kees,
very likely Ijuhya tetraspora.
Our paper on the genus is in open access at the website of Ascomycete.org
Cheers,
Jacques

Re : Ijuhya spec. on leaf of Vaccinium vitis-idaea
Thanks for your comment. In the Netherlands, this species only occurs on tree bark,especially of Salix. It is very rare here. Is it also possible on leafs? With Regards, Kees.

Re : Ijuhya spec. on leaf of Vaccinium vitis-idaea
Hello Kees,

Your find is very similar to what I found before in the Netherlands. I found I. tetraspora both on wood of Cytisus scoparia and on a decayed apothecium of Hypocreopsis lichenoides.


With regards,


Marian Jagers

I find the paper Four new species of Ijuhya (Bionectriaceae) from Belgium, metropolitan France and French Guiana on: https://ascomycete.org/Portals/0/Archives/AscomyceteOrg%2009-01%2011-18.pdf  It most be Ijuhya tetraspora for sure.

Thanks for the comments.
