Have you some idea about this fungus growing on leaves of Juniperus sabina at 1700 m of altitude?
Ascomate are blackish, more or less sphaerical, superficial on a thin subiculum, 0.15-0.20 microns in diameter. I don't know if it is ostiolate.
The saccate asci seem to be bitunicate, 70-100 x 30-32 and contain 8, first hyaline later greenish or greenish-brown, smooth, 1-sepate, 22-31 x 9-12 ascospores, the septum near the bigger cell. Hairs or setae undulate, brownish, 1-3 septate, up to 75 x 5, walls 1-1.5 microns thick. Neither paraphyses I have seen.

I don't find this fungus on the Venturiaceae ones. Maybe a lichenized ascomycete?
Have you some idea?
Thanks in advance

this is maybe only of minor help. Here is a checklist of fungi on Juniperus by D.B. Belomesyatseva:

scroll down to vol. 4. I currently dont't have the time to sort it out...
Best regards

Thanks a lot, Martin
J. Linde said me this fungus of Alain Gardiennet seems to be close to the mine. Later I'll try the IKI reaction looking for a blue reaction that perhaps I didn't see by using Melzer and not IKI.
