Bonsoir.
A friend of mine has transmetted to me pictures of an Orbilia for ID. But with informations he has given to me, I don't know...
Data :
Ascus without croziers, apex rounded sometimes truncated. x8 spored.
Spores ovoides 3,7-4 x 1,5-2,1 um Q=1,8-2,5
Spores with a black point (guttule ?) at one end. The first four black points are directed to the base, the four to the apex.
Paraphyses capitate.
Any Idea ?

Re : Orbilia
This looks much like the common O. tremulae. Earlier I would have said O. eucalypti, but O. tremulae differs in smaller spores not exceeding 4 x 2 µm, and often yellowish apothecia, together with a lack of drought-tolerance (growing on moist wood on the ground). Genetically it is very distant from O. eucalypti. Its anamorph also differs and matches morphologically Dicranidion inaequale.
