Vasileios KaounasAt the beginning when I saw the round spores I thought are Pithya cupressina, but the asci are a lot bigger and the periphery of the cap shown some hyaline hairs combined to form a small triangle

Hi Vasileios,
the "hairs" are strange. They remind me to Pezoloma ciliifera, but this is an inoperculate discomycete.
It exists a forma albida of P. cupressina, see here: Pithya cupressina f. albida L.G. Krieglst., in Krieglsteiner, Z. Mykol. 51(1): PAGE 118
