I think it is A. lignatilis or is there any alternatives?
Spores 16-19 x 8-9, hyaline at start, smooth.
Best regards,

Your mushroom looks a lot like A.lignatilis; the ornamentation corresponds well as does the shape of the spores, quite characteristic, rather pointed at the ends. The margin of the apothecia is also well marked, furfuraceous. Have you noticed the presence of a small stipe under the apothecia?
Michel.
I searched in my keys for Ascobolus genus, and I don't find both epimyces and lignatilis.
Can you provide me a more complet key for genus Ascobolus ?
Thanks in advance.

These two species are very close (lignatilis and epimyces), but I find that for epimyces the spores are not pointed enough (for me they should be more diamond-shaped) and the ornamentation a little different. Perhaps if you still have material you could let it mature a little more in order to see spores again.
Michel.

I have some apothecia left but they are al in the same state. It was collected in the summer but havet got the time to look at it until now. But i couldent se any realy dimonshaped spores when i did som new cuts. so then i will be happy to cal it ligniaris. It have been collected in the same area before.
best regards,
Robin
