Cryptodiscus on Pinus

These apparent Cryptodiscus fruitbodies with a pale margin were growing on a fallen, decorticated Pinus sylvestris branch in a mesic heath forest.
Asci narrow, 8-spored, IKI negative (not sure about croziers). Paraphyses with a swollen, sometimes irregularly shaped tip.
Spores 2-celled, measuring 7.5 - 9.7 × 2.0 - 2.6 µm, Q = 2.9 - 4.9; avg = 8.4 × 2.3 µm, Qav = 3.8; n = 8.
I think the macro and micro would support C. foveolaris, but that species is supposed to grow on hardwood. Could this still be it, or is there another alternative?

Re : Cryptodiscus on Pinus
I do not know a reason why C. foveolaris should not grow on conifer would, occasionally. I think it fits rather well - without having a very close sight.
Yours, Lothar

Re : Cryptodiscus on Pinus
I saw it only once on a conifer (Pinus), but many dozen times on angiosperms. Cryptodiscus pini has larger curved spores and is much darker.

Re : Cryptodiscus on Pinus
Thanks Lothar and Zotto. I guess I'll name this C. foveolaris then.
I'm also rather familiar with C. pini -- it seems to be very common here. In fact I found it on the same trip on another branch just minutes before, and have found it before many times with almost no effort.
