Yellow disc on Quercus

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?

This looks much like Phaeohelotium epiphyllum (= Hymenosc. e.)

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
