Trouvé au sol, sur bois mort et décortiqué de Picea (sur toute la longeur du tronc), apothécies 0.5-1.5mm, immergée dans le bois, hyménium noir, asques 39-48x6-9µm, IKI-/KOH+IKI+, une spore par asque, spores 22-32x6-7µm, d'abord hyalines, puis à maturité brunâtres, 8 à 9 cloisons transversales, paraphyses septées, fourchues et brun au sommet.
Je pense à Mellitiosporium propolidoides. Merci de confirmer ma détermination.

Re : Mellitiosporium propolidoides
Hi Elisabeth,
I think there's little doubt about M. propolidoides. In my experience it is a rather common species in montane forests, growing on decorticated wood of conifers (I have collected it on Picea and Pinus sylvestris) which is often bleached around the apothecia. It seems to prefer old-growth forests or at least semi-natural areas, is that also the case in your find?
Here are some photos for reference: http://ascofrance.com/search_recolte/4042
Best wishes,
Gernot

Merci Gernot,
Der Fundort ist ein Altwald auf rund 1000m, ohne Unterhaltsarbeiten. Was fällt, bleibt liegen.
