Hello, forum!This specimen was found on Salix wood.
Apothecia 1-2 mm in diam, cream-coloured, on the short stalk.

Asci 38-48*4-5,5 um, IKI "-" (as far as I can see)
Hairs very slender, hyaline, incrustated with some substance. 45-55*3 um
What are your opinions about this?

Re:Phialina? Calycellina?
Hallo Irina,
I think you have Calycina vulgaris, the dimensions and guttulation fit quite well for dead spores, the hairs you mention i don't see, but what is in the drawings i would judge as paraphyses.
best regard

Re:Phialina? Calycellina?
Thank you very much, Stip!
The specimen was collected on 20 December, so spores probably are dead.
Maybe these are paraphyses, but it seemed to me that I also have seen very tiny hairs on the outer side of apothecium.

Hi Irina,
There are tiny hairs on the outside of the excipulum but with a averige of about 15 mu long.
They are best seen when you put a part of the excipulum with the outside up in water and gently add the coverglass without tapping ( so there remains some air between the hairs)

Hi Irina
I agree with Stip. If we can be sure about the IKI-negative asci I have no doubt for Calycina vulgaris.
The species is not very common, and I had it mainly on Salix wood or bark, but also on Rosaceae etc.
Zotto.

Re:Phialina? Calycellina?
hi there
Here in Denmark it seems to be a very late season thing and can occur in abundance on attached Salix twigs - so maybe it is rather common when the mycologists are hibernating :)
