Hymenoscyphus calyculus coll.?

These were growing on a twig of a deciduous tree (probably Salix) in a somewhat dry location.

The asci are without croziers, IKI+(bb). I think the paraphyses weren't in the best condition -- not many VBs were to be seen. The spores measure 18.8 - 24.6 × 4.3 - 5.1 µm.

Maybe something close to H. calyculus?

Re : Hymenoscyphus calyculus coll.?
How large are the apos? A clear paraphysis I cannot see. But: H. calyculus has croziers, like H. subferrugineus and H. conscriptus. Could be H. virgultorum (in my s.str. folder).

Re : Hymenoscyphus calyculus coll.?
Ok, thanks! The dry apos are up to 1.3 mm wide. There's a single paraphysis in the middle of the bottom middle square.

O.k. I saw it of course but I wasn't sure what it is.

I guess it's seen some life...

Surely not the regular habit. Perhaps damaged, I cannot interpret.
