Åge OterhalsI found this pyrenomycetous fungi in mountain area
Hi to every one,I am looking for help after the collection of a tiny, stipitate, white- hyaline creature on (I think ?) Frullania. on Picea standing and living trunk.
Apos from 0,1 to 0,2 mm .
Ascus 50 - 80 x 11-12,5 , IKI negative , H+, clavate with a narrow base
Paraphyses with the last cell very broader , with CRB + vacuolary content
Spores with OCI 4,5 , most often with 2 larger guttules x 2,8 µm and smaller ones, 13-15 x 3-3,5 µm , mostly 1x septate oustise ascus (and also sometimes inside) .
I apologize for the rather poor picture quality and the lack of information on the excipulum (at least)
Amitiés et merci, Michel
the pictures look wonderful! I have a slight idea: Phialina anomala. I have this in my Hamatocanthoscypha folder, despite of the strong VBs. That fungus is sessile, however, and has short +/- curved hairs.
Your fungus has VBs as I can see in the IKI photo. If you have still material, please do a photo showing VBs in water, and perhaps also an external view on the excipulu, without pressure (possible hairs, VBs).

Merci Zotto,
You can see VBs (weekly refractive and rather homogeneous) in water in image 3 above and I join more pics but I still have difficulties to understand the fungus structure . No curved hairs anyway.
I would have excluded a Hyaloscyphaceae
Amitiés Michel
Hi again,
I wonder whether these new images could help :
- the outer surface develops as an anamorphic state (the same process I observed in about twenty ''apos''), the swollen terminal cells react in IKI as if containing VBs . These cells appear on the surface and among asci
- With KOH before IKI, the ascus walls totally becomes blue
Michel
But this habitat should have been searched intensely, by JPP for instance....
Could you clarify the host genus?
Many thanks in advance
Nice that you did find it !
There was unfortunately no conclusion for this find.
Among other mycologists consulted, Peter DObbler suggested the taxon Vezdaea , here is his answer :
should be compared with the lichen genus Vezdaea, e. g. V. stipitata. It is presumably accidentally on withering hepatics (surely Radula complanata) where algae are present. The iodine reaction is typical of Lecanorales. Good luck! Peter
AmitiésMichel
Reallys a nice fungus!
Here are my pics.
I wonder how you came across my post on Ascofrance from 2015 as there was then no information on a possible lichen sp. ? May be from the subject containing hepaticolous ?
Amitiés. Michel
Long live Ascofrance!
Nous sommes heureux de contribuer à la poursuite de son fonctionnement .
