Re : Unknown pyrenomycete
The ascospores and the hairy Perithecium remembers me to the genus Camptosphaeria.
But I don't know a species with rigid brown hairs.
We need also some informations about the asci (apical ring, subapical globolus and others)

Hi Joop!

I think that Norbert is on the right track, actually your fungus resembles the kind Camptosphaeria. I have found that once a species like this and I am enclosing an immature spore photo that looks like yours.


I hope you can have more information.


Michel.

Re : Unknown pyrenomycete

Thanks Michel, I also found another species that looks the same but has other characters. I also asked David Malloch for assistance.


Found on horse dung.
Perithecium: Long neck 199x110 um, no hairs.
Asci: 8-spored; expanding as soon as they come in contact with water; 196x34 um, several measurements of the width after expanding 30.4-42.6, apical ring 6.9 um wide.
Spores: bi- and triseriate; immature spores 47.6-50.2x14.4-15.0 um; with two cauda's on each side with a length of 33.5-35 um and a width of 5.0-5.2 um; having rings in the upper part of the cauda; it seems that there is a fixed part on the spore end and the distel end of de pedicel before cauda starts with a length of 9.0-10.0 um; mature spore heads 22.8-26.7 (-27.6)x13.3-15.9 (-18.0 um; colour at first light brown and dark brown afterwards; pedicel 19.2-21.7x6.2-7.8 um. cauda not always visible.

Re : Unknown pyrenomycete
The last fungus you posted is a Cercophora species for sure, and maybe the first one too (in the last photo you can see the "swelling" of a young ascospore).
