Hello
Today´s morning  I have found this Cosmospora (I think that It´s in this genus) on Juglans regia in a riparian forest.

Ascomata 250-400 x 150-250 µm, pyriform, red (purple in KOH) and with 40 µm papilla.

With brown hifal hairs.

Asexual state with hialine and smooth conidia, 5-6 x 1.5 µm.

Sexual stage with smooth spores, hialine or with purplish pgment, one septa and two nuclei. Me = 14.6 x 6.4 ; Qe = 2.3 µm.
Asci without croziers. 90-110 x 6-8 µm.

I have not bibliography or any key... I know that is very difficult but if anyone can help me...

Thank you very much!
Best regards
