Orbilia sp. on Quercus

This was found on the underside of a decorticated piece of small Quercus branch.
Most paraphyses were only slightly swollen at apex and were embedded in a terminal amorphous matrtix, as can be seen in the accompanying images.
Ascospores mostly parallel-sided, curved and with a relatively short spore-body; half the ascospores lying in a reversed position.
Guidance appreciated . . .
Cordialement

Re : Orbilia sp. on Quercus
Hi Chris

not easy! Could you please make a sectio through the margin? The orientation of the cels is important and also the presence of glassy processes.

Any conidia observed?

In the worst case it is O. auricolor.

Re : Orbilia sp. on Quercus
Thanks Zotto
I'll have a go, but compared to many on ASCOFrance my section-cutting skills are a bit rubbish. Looking at your 'auricolor sl.' folder it looks close . . .
I have a number of finds from yesterday to work through but I shall come back to this one.
