Re : Unkown asco on horse dung
Merci Michel,
Can I use cotton blue when looking for the gelatineus sheath or do you prefer another colorant?

Hello Joop.
Your first photo seems to confirm Arnium macrotheca we see the gelatineus sheath.

Re : Unkown asco on horse dung
Hello Joop & Michel,
this interesting species seems to be rare in Germany. I saw it only three times, all gatherings on old horse dung. Actually it's growing in moist chamber!
Half year ago I did a little portrait at Pilzforum.eu, sorry only in german!
The spores are in Indian Ink.
If you want, you can have a look at it here:

Maybe that you can't see the nice pictures by Rada, therefore you have to be registered :-(

Hello Norbert,
I have a little piece of horse dung in culture (10x10 cm) and so far I have had 15 species and still growing.
