Podophacidium?

J'ai fait la récolte hier d'une minuscule espèce qui me semble posséder les caractéristiques d'un Podophacidium, mais dont la couleur ne semble pas correspondre aux deux espèces décrites.
Apothécie jusqu'à 2,5 mm, turbinée, sessile, recouverte d'une couche orangée granuleuse sur toute sa surface s'ouvrant pour former une étoile.
Spores 11-17 x 5-6, lisses, munies de 2 ou 3 grosses guttules et parfois de plus petites.
Asques inoperculées, munies de crochets, 120-135 x 10-12 µm, à pore apical bleu dans le Lugol.
Paraphyses, en crosse ou droites, parfois ramifiées à l'apex, 2-3 µm de largeur.
Pourriez-vous me dire ce que vous en pensez ou m'orienter vers un autre genre si je fais fausse route.
Merci d'avance.

Re:Podophacidium?
Dear Renée
Clearly this is Podophacidium, and I feel your marcro is not far from photos in Breitenbach or Schmid (the latter here attached), or my old drawing on the DVD. I am unaware of more than 1 species in that genus. I only wonder why Breitenbach and Schmid figure medium-sized LBs in the spores which I otherwise see as very big drops as wide as the spore.

Re:Podophacidium?
Dear Zotto. In the description of Seaver in North American Cup Fungi, it is said that the envelope is black, and not orange as in my specimens and your photo. It is why I thought it might be another species. I already found specimens with the black envelope (I include here a picture). So you think that orange colour could fit into the description of the species?

Re:Podophacidium?
I actually noticed this colour difference from the plate by J. Labrecque and R. Labbé. As you have both forms you can compare the microscopy if there is any difference. By the way, also Boudier figures yellow apos with a brown margin, see here.
The only further species in IF is P. pulvinatum Raitv. & Järv 1997: on fallen leaves, but that differs in much narrower spores (17-20 x 2-3 µm) and apos without teeth. I have a drawing of what might also be a Podophacidium, on pine wood, with spores 13-17 x 3-3.3 µm, apos reddish-brown, with prominent teeth (HB 6955, on DVD as Phacidium).

Re:Podophacidium?
In my notes on the first collection (black form), I have:
Ascus 100-140 x 9, with croziers
Spores 10.5-11.5 x 4.5-5, multiguttulate
Paraphyses 1.5 µm wide and of the same form as the orange form
All the elements are similar in shape, but the size of the spores appears smaller than in the orange form.
In Breitenback and Kranzlin, the envelope is also black. The measures in that book fit with my own measures of the black form.
This is very interesting!

Re:Podophacidium?
Do you have microphotos of the black form? You say "spores multiguttulate". P. xanthomelum has always two very large drops and two smaller at the ends. This is also the case in a find by Stip Helleman which has a black margin. Hope he does not care when I place it here.

Dear Thomas,
I wrote to Jens Petersen more than a month ago but never got an answer back. I would agree to provide you some pictures.
