Hello Joseba,

in my opinion, your collection does not look like M. ventosa, macroscopically. Typical for this species are the yellowish colors (not purely grey-white) without a lighter margin.

Hello,

I agree with Zotto that the ascus pore reaction and the oil content of the spores look like in Mollisia elegantior. But macroscopically it looks a bit different, or may be you have quite young apothecia. The spore size also is a little bit smaller than usual in M. elegantior.

But all in all the best idea is M. elegantior nevertheless. You should try to locate the marginal cells to see, wether they are multicellular or not.

best regards,

Andreas
