Hello everyone, On dead wood of Cytisus scoparius

Philippe PELLICIERBonjour,Récolté sur bois pourrissant de feuillu

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
