Dear Forum,On decorticated wood of Castanea,I foun
sur feuillu, spores 4,5-5,2 x 1,8-2,2 µm. Peut-être O. coccinella ?
Merci.

The spores look very cylindrical, quite unusual for O. eucalypti = coccinella s.auct. (typical O. coccinella is a nordic species with reniform spores).
Can you show me an ascus photo too? What is the substrate and was it on the moist ground? The colour is a bit intense, unless it grew exposed for repeated drying.
I have one collection with cylindrical spores, see below. It grew in 3 m above ground on an attached branch.

I'm sorry but here are the spores that I observed, it is therefore O. leucostigma. The first observed were probably parasites spores because I doubt that there are two species here.
