Good evening,
I found this Podospora/Schizothecium on hare dung, a few days ago.
Fruiting bodies 400-550 x 250-300 µm, blackish-brown to black, usually only the tip protrudes above the subtrate. No real hairs seen, sometimes there are a few thin ones (~2 µm wide) on the base of the fruiting body, but I can't exclude they belong to the dung. Neck containing agglutinated hairs, forming triangular scales with a dark tip.
Asci 8-spored. Spores with one brown cell, 17-19 x 10-11 µm, one pedicell, 6-8 x 2 µm and often there is also 1 appendage (cauda) visible on the other side of the spore. This appendage falls easily from the fruiting body, resulting in free spores often missing this appendage.

Given the agglutinated, scale forming hairs it should be a Schizothecium. Using the key in Ellis & Ellis leads me to S. vesticola. But according to the description in 'Fungi fimicoli Italici' and 'Coprophilous fungi in New Zealand. I. Podospora species with swollen agglutinated perithecial hairs' this species has 2 long caudae, I've only seen one rather short cauda.
Another possibility could be Podospora fimbriata, but I can't find a good description of that specie, but the little information I found stated this species is found on goose dung and doesn't have caudae.
Most of the other species seem to have different spore sizes, or obvious hairs.
