Small gregarious disco

Ascomata less than 1 mm on average, shortly stalked, in youth whitish or creamy white, later turn red during the maturation or when damaged.
Medullary excipulum with textura intricata, ectal excipulum with textura porrecta (really?)
Asci IKI+ with croziers, max. 60 µm long. Paraphyses are cylindrical, with VBs at the lower part only (dead material). Hairs sparse, distinctly narrowed on the top. Ascospores hyaline, one–celled, fusiform or cylindrical, however one end is wider, Me = 7.3 × 2.9 µm ; Qe = 2.5.
Thanks for your help.
Marek

Re : Small gregarious disco
Hi Marek
I do not have a certainty but I think you should compare with Calycina subhyalinula / hyalinula.
I see in your photos, a few features suitable for these species.

Re : Small gregarious disco
Difficult to say. The thick-walled warted hairs on the 6th pic are not part of the fungus I think.
A Calycina seems quite probable, the red colour change is typical. C. hyalinula isn't a bad idea indeed. In that species the blue reaction is restricted to the lower part of the apical wall thickening. Are there more such photos showing the ring?
I am a bit unsure what these apically narrowed elements are. perhaps phialides forming small conidia?

Re : Small gregarious disco
Thanks, Mirek, you gave me very good direction, I saw your photos on the site Grzyby Puszczy Knyszynskiej. It fits quite well.

Re : Small gregarious disco
Thanks, Zotto.
The thick-walled warted hairs on the 6th photo is some rubbish, of course.
The restriction of the blue reaction to the lower part of the apical wall thickening - do you mean something like this (1st pic)?
And these narrowed elements - you have some photos of the same structure on your disk (e.g. by Mirek Gryc - 2nd pic).
Mirek suggests C. hyalinula or C. 'subhyalinula'. What is the difference?

Re : Small gregarious disco
Your photo of amyloid asci shows very well what I meant! And the phialide is pretty clear.
I am unaware of a species called subhyalinula, but I must admit I created this name for my folder. The reason was apparently the position of the amyloid ring, at apex or at base of thickening
. In the Orbilia monograph p. 1674 I have a short note on Orbilia hyalinula which I consider a Calycina or perhaps a Cistella with smooth hairs.

Re : Small gregarious disco
Well, everything is clear now except for one thing: may I call it C. hyalinula or C. aff. hyalinula?

Re : Small gregarious disco
I remember the type has the ring at the top, so yours should be aff. hyalinula.
