Hi Yannick!
looks like Ascocoryne. You say medulla globulosa, is that right? I would expect a hghly gelatinous medulla of thin hyphae here. A. cylichnium is excluded by the small spores.

Hi Zotto !
Yes, textura globulosa just under ascus and after, as you say, all is highly gelatinous with thin hyphae.
So dark for an Ascocoryne, no ?

The macro looks a bit colourless, maybe it is something with the camera rather than the fungus?

No no. Very dark in reality.
So, which specie do you think about ?

Re : asco à identifier
With these spores and the internal gel it is either A. sarcoides or A. albida (= A. solitaria). Without the anamorph this is not so easy.
