Phaeohelotium geogenum

Hi
It is not a rare species in my area, but it is also not common. I have already met him a few times (I present some of them in my atlas) but I decided to post this one on the forum because I noticed some details that I did not see in the previously found collections.
Please note the tops of the paraphyses and the short hair on the ectal ex. near the edge of the ascomata.
Are such features typical of this species?

Re : Phaeohelotium geogenum
Yes it is. The substrate is Quercus seeds, I suppose.

The spores should contain globose VBs in the optimum stage (with low refractivity).

Cannot remember these curved hairs.

Re : Phaeohelotium geogenum
Hi Zotto
Yes it was Quercus seeds. That day I also found an ascomata growing on a mulch made of Quercus leaves and spruce needles. It seems this species likes a different substrate as well. I also found it on a badly decayed Betula trunk lying in a stream.
Globose VBs have occurred but very rarely.
On my page with this genre I have two other collections shown ... although these are not all that I found.

Re : Phaeohelotium geogenum
The left spore is dead. My impression was that the species is confined to Quercus, but grows on all kind of litter under oak. But actually I have also Betula (2x) and Fagus (1x).

Re : Phaeohelotium geogenum
I suspected it, but since I show different spores, so I put this photo too.
