Re : Hamatocanthoscypha sps perhaps
Not a Hamatocanthoscypha. I think it's all paraphyses. Maybe without actual hairs? Seek the end cells at the apo margin and continue down towards the stem, that's where the hairs are - that is , if there are any. Sometimes they are lost in a squash mount if they are tiny and in small numbers.
But, I cant answer your question, dont know the genus... Good documentation otherwise.

Re : Hamatocanthoscypha sps perhaps
Hi Tima,
With thanks for your thoughts. Makes sense as why have hairs if they do not extend beyond the apo margin/asci. I will double check as you suggest. Otherwise I'll focus on genera with hooked paraphyses. Strange maybe that some change colour, some don't and are different widths, which is why I thought they were hairs. Tony

Hi Timo,
Checked again and think you are right but with very variable paraphyses, 20% with uncinate tips, 50% slightly swollen curved, 25% straight, 5% thick Hockey stick end! Most two branched and with yellow VBs or resin, 2/3rd into thinner hyaline base. Spores seen a little easier but again variable now lasrger length 6.58 - 12.90 x 1.72 - 2.28 µm. Medullary excipulum easier in Congo Red showing sub-spherical and more prismatic at Ectal. Checked evrything I know and came up with Calycellina/Hymenoscyphus type maybe due to yellow/VBs but otherwise mystery. I might try and get this sequenced unless anyone has any other ideas.
With thanks Tony

Re : Hamatocanthoscypha sps perhaps
The combo of ecology & morphology (especially the paraphyses) doesnt ring a bell to me. I have found remotely similar material from large-diam decayed tree trunks. I have no no name for those either. The content suggests Calycellina/Phialina - Pezizellaceae yes. But it appears this character is not restricted to that clade. Sequence are always helpful.
