    Apothécies en groupes, diam -> 0.8 mm, sessiles, en coupe s'étalant ensuite; hyménium de couleur datte, poils blanchâtres en lignes radiales, cils blancs.
Poils + ou - fortement incrustés, brunâtres sous le microscope, 32-40 X 2-3 µ; cils -> 60 µ.
Asques minuscules, courts, 8-sp, 24-28 x 5-5.5 µ, IKI -, spores bisériées. Spores guttulées, 4.5-6 x 1.5-1.8 (2?) µ, hyalines ou très pâles.
Paraphyses non observées, peut-être absentes.
Aucune idée...

                On dirait un Hyalopeziza avec ses poils à paroi épaisse, réfringente. Mais avec des spores aussi petites, je ne vois pas trop de quel côté chercher...

                Thsi could be Hyalopeziza trichodea known from Pinus needles.
see http://www.ascofrance.fr/index.php?r=forum&page=viewtopic&id=7004&highlight=trichodea#msg7004
though only known from needles in the literature, as it seems.
Your asci are a bit short, but otherwise....

                Hm. C'est possible aussi que, vu les conditions climatiques exécrables cette année, certaines récoltes soient atypiques.
And thank you Zotto. It's quite similar indeed, but the hymenium seems darker on my sample, and maybe I've been a bit confused because the hairs seemed incrusted in my sample (photo below). Artefact?

                Did you take this pic with oil immersion? Your photos are a bit unsharp, perhaps you must more open the aperture of the microscope? Could you make a test: Place min. 5% KOH to the preparation, or if less then shortly heat the mount. Hyalopeziza glassy hairs should be resistent in KOH. perhaps then the surface of the hair becomes more clear? Or gets smooth??
The colour is different, I also noticed. You ar right, I am wrong with H. trichodea. Your find is the same what Antoine Ayel once gave me (HB 4050, 4052), on Pinus bark. I have this presently in Hyphodiscus, but surely it belongs more in Hyalopeziza. The hairs are granular, this was the important characteristic that gave me the idea. The spores have often 4 oil drops.
Enrique also found this species (ERD 4442), though this is said to be on Quercus.

                Yes, it's taken with immersion oil. I'll try opening the aperture more.
I still have the specimen in the fridge, I'll do the experiment in KOH tomorrow and I'll tell you what happens.
And yes, it grows on the bark of the tiny dead branch.

                Ectal excipulum in KOH:
And I still have the specimen in the fridge. If you're interested in studying it (if it's something interesting), I can send it to you by mail. I just need your address.
Full data's are:
Mont des Pins, La Rote, Bomal s/Ourthe, Durbuy, prov. LX, Belgium, and date of gathering: 27.02.10.

                Dear Luc
yours is exactly the same as Enrique's and Antoine's finds. I wonder whether there is nothing in the literature. I think I would have notized if there is something in Grelet (?).
But I have little time so I must not study your collection now. I think the species will show up again at some time. A possible relationship is quite evident with what I have possibly as Hyphodiscus sericeus on the DVD (HB 5851 etc.), though there the hairs are never such glassy-thickwalled, and the spore contents are different.
The true Chlorosplenium sericeum is probably the same as Erinella aeruginosa, the green disco with 40 µm long spores.

            Re:Discom. poilu s/ Pinus sylvestris
                There are chances I will find this species again, indeed, but this sounds like the kind of things one finds when not searching especially for it :-D
I'll have a look in the DVD then.
