Big spored Hyalopeziza?

Hello forum,
these about 0,1-0,2 mm wide ascos grow on Prunus padus leaves and are a bit red coloured.
The spores are guite big 12-18x2,5-3.
The asci are 40-50x7-8.
The hairs are about 15-40x3-5 and have a basal lumen and seemed to keep their shape in KOH.
I had no luck in determination. Any ideas of the species?
Marja

Re : Big spored Hyalopeziza?
Hi Marja, did you compare Hyalopeziza raripila and Naevia diaphana? They both have a red reacting apical ring and stand in the Calloriaceae in my Iridinea folder.

Re : Big spored Hyalopeziza?
Dear Zotto,
I naturally checked H. raripila from Raitviir's opus and this had too big spores anf did not grow on dead herbaceous stems. But I suppose, that H. raripila will be my determination now.
Thank you : Marja

Re : Big spored Hyalopeziza?
Yes, spore width exludes diaphana.
