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

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?

The images are not good, but the spores are.
Send more pictures. If you want more resolution, shipping to  the private...............

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.
