Hi Leandro

what collection! Does it have a substrate too? Can you show me a 7 mm large apothecium? How large are the figured ones?

Hymenosc. menthae rarely exceeds 2.5 mm, and never 4 mm diam. Of course, the persence of croziers excludes this species.

Re : Hymenoscyphus ??
Can you send me this collection?

But you must know if the substrate is herbaceous, perhaps a petiole, or a twig?

Re : Hymenoscyphus ??
I think it's a twig
I send you this collection
Thank you zotto

Re : Hymenoscyphus ??
It is from Spain, right? Is there only these few apos? if you try sending fresh it might get worse. Since you figured the vital state, you could send it instead in dry state.

Maybe my mind wakes up next, but presently I have no idea what it is. You know my address?

Re : Hymenoscyphus ??
Yes, I know your address, i have sent you something previously.
I send in dry state.

Re : Hymenoscyphus ??
Hi Leandro

yesterday arrived your sending, thanks a lot! I studied it today. Well, it is indeed a Cyathicula! Strongly gelatinized ectal excipulum (text. oblita, see below). I saw no crystals but they are inconsistently present in the genus. The spores and croziers would fit C. coronata, but the margin is entierly without teeth, of course. I found the ascus apex inamyloid or very faintly amyloid (see below), something I do not remember for C. coronata. Do you have a photo in iodine since you say J+?

Your nice apo photo is a bit reduced, can you please send it to me by mail in higher resolution? Also I would like to know the collection data.

I also looked at the substrate. It is clearly herbaceous and fragile, and it looks a bit like a monocot (not sure) after I made a section.

Oh yes, good photos! Distinctly more amyloid than mine.

Please send to zotto@arcor.de

Thanks!
