Yellow disc on pinus

Lying on a debarked pine branch in a heathland we found these sessile yellow fungi. When young they are discs that resemble an Orbilia, when they get older they become somewhat irregular lumps that are grainy and you think more of Mollisia-like.
Spores apple seed-shaped, measured in water:
(8.3) 8.7 - 10.5 (11.2) × (2.6) 2.8 - 3.5 (4.1) µm
Me = 9.7 × 3.2 µm ; Qe = 3
Asci Lugol +, croziers +
(54.2) 54.25 - 65.7 × (6.8) 6.85 - 8 µm
Me = 60 × 7.4 µm ; Qe = 8.1
Paraphyses, septate, branched and at least upper part granulated.
What genus could this be?
Thanks in advance, Margot&Geert

Re : Yellow disc on pinus
I think we need the excipulum. The apos are up to 1 mm?
There is a white form of Durella suecica as I remember.

Re : Yellow disc on pinus
Thank you for the reply.
The discs are 1 to 1.5 mm in diameter.
We tried to make a section of a disc and numbered the different structures in the overview photo.
The numbered structures can be seen in the detail photos.
In the overview photo it looks like there is an algae layer under the disc, this algae layer is also next to the discs.
Hopefully it's that clear.

Re : Yellow disc on pinus
Interesting! This rules out my idea. At the moment I am helpless.
Calycina ("Pezizella") pulvinata (folder Antinoa-like) might be similar but is on pine needles.

It will remain uncertain, thanks for your help.
