Unknown pyrenomycetous fungus growing on cowberry

Could you help me in the right direction with this pyrenomycetous fungus. It was growing 14.04.2025 on Vaccinum vitis-idaea in central Finland. There several groups of fruitbodies on the stem. Diameter of the group depicted in my photo is 0,9 mm, individual fruitbodies were about 0,25 mm in diam.

Hi Henri,

compare also Gibbera compacta:

C.L. Shear et al, Fungous diseases of the cultivated cranberry. USDA Technical Bulletin 258, 1931: 13-14. (attached)

see also this photograph of Gibbera vaccini:

Re : Unknown pyrenomycetous fungus growing on cowberry
Thank you.  Spore size and substrate seems to favor G. vaccinii here.

Re : Unknown pyrenomycetous fungus growing on cowberry
Well, I wonder if G. vaccinii and G. compacta are two different species...
