Re : Orbilia de Quercus
Javier, your  Spores seem strange, too green, may be algae ? also ascus  too wide for eucalypti= coccinella

Re : Orbilia de Quercus
Hi Javier & Jean-Paul

Jean-Paul is right, and you have indeed the correct spores inside the asci. I see a spore body at one end. Could you please send me this image nr. 2 in high resolution? Perhaps also with a scale?

The Dicranidion is interesting, but we do not know a species with such crenulate margin in combination with Dicranidion.

Could you please look at the margin whether there are glassy processes or what these teeth are?

Re : Orbilia de Quercus
That's fine. I am still unsure, and yes, please send me the ascus photo Nr. 2 and also the macro in min. double resolution.

My idea is a but that it could be Orbilia microsoma. Important is also that the asci are 8-spored, because there is an O. pleiomicrosoma with 16 spores.

These microsomas have short glassy processes at the margin.
