Hello.A suspected Hymenoscyphus sprouting on a thi

Good evening everybody,
This afternoon we found some small yellow discs with dentate margin on leaves of Quercus.
The asci were cylindrical, thick walled, 120x14µ, 8-spored and IKI pos. Paraphyses were filiform and contained long refractive vacuoles. Spores measured 20-22x6-7µ and had 2 large guttules.The outer excipulum consisted of textura angularis.
I think it is something of the subfamily Dermateoideae.
Someone could help me further?
Zotto;
You are right I have been misleaded by the general key in Nordic Macromycetes where the slightly brown excipulum and the angular cells brought me to the Dermateaceae.
But all the typical features of P epiphyllum were present including the reddening after damaging
Thanks
Marc
