Hi to allThese small and narrowly sessile ascomata up to 400 microns grew on Betula alba wood at 1650 m of altitude. KOH negative.
I think is an Amicodisca species but their asci have persistentely croziers.
What's your opinion?
Many thanks again

Re : Amicodisca sp. with asci with no croziers
Hello Enrique
I do not know this genus (I wish I did!) but looking at Zotto's DVD not having croziers seems to be quite typical of it
best wishes

Re : Amicodisca sp. with asci with croziers
Thank you, Chris. I'm sorry but I was wrong and wrote that the asci have not croziers (typical for Amicodisca) when my collection has asci WITH CROZIERS !

Re : Amicodisca sp. with asci with croziers
Dear Enrique
I believe this is very similar to A. virella, mainly differing in croziers and slightly smaller spores.
There is a key in a recent Japanese paper (Han et al. 2012), but it does not include your species. I send you the pdf.
Probably undescribed!

Hi
Zotto, can you send it to me too? I am interested in this genus. Nice finding, Enrique.

Re : Amicodisca sp. with asci with croziers
Thanks a lot, Zotto.
I think could be an undescribed species of Amicodisca but the question is: Which is the importance of having or not having croziersr to differentiate two species ?
Enrique
Thanks for the paper

Re : Amicodisca sp. with asci with croziers
This is actually not always clear. It depends on the case. But generally the difference in the ascus base seems to have to do with a specific split of populations which do not further interbreed. If you find other distinguishing features it is easier to make such a distinction. But in the case of H. albidus/pseudoalbidus we have only slight correlations in other features of the apothecia. But we have strong pathogenic differences, and also such in the anamorph. Who knows what Amicodisca does in pure culture...
