Pardon escipulum claire, brun dans le base de l'apotecium, qui est très petite (0,1-0,5 mm)
Merci!!

Re:Mollisia
Dear Tania
Mollisia species are usually not very host specific, so identification of your fungus requires more data. Are the asci amyloid, croziers? How deeply brown is the excipulum, margin in section (hairs?).
Your images are too small. Did you put them as bmp? It seems so because loading is rather slow.
Important would also be some vital characters. Especially: are the spores inside the living asci always aseptate? Perhaps you can recollect the fungus?
Cheers

Re:Mollisia
Dear Hans
Asci amyloid, not croziers at the base, excipulum few brown. In the photography it can appreciate that in dry they are totally yellow.
The espores inside asci are always aseptate.
I Cannot recollet this fungus, The especimenes come from herbalist's material
The speciments were growing in a xeric environment (Cistus monspeliensis bushes) at Cap de Creus, Catalonia, Spain.

Re:Mollisia
Dear Tania
I am quite unable to name this species. the characters are not very extraordinary, only the yellow KOH-reaction and the a bit large spores seem characteristic, also the xeric habitat. What I doubt a bit is the absence of croziers. You may be true, but this character requires careful observation and illustration in KOH plus Congo Red. It is a very clear character, but difficult to see anyhow. Most Mollisias have croziers but a few don't have, so the absence would be something like a "sensation".
Did you test Andreas Gminder' s or my Mollisia key?

Re:Mollisia
dear Hans,
testing your keys it seems M. prunicola, but I don't have observed croziers, What might it do to observe the croziers?

Re:Mollisia
Where I might find good descriptions of the speciesof the genre Mollisia? specielly of Mollisia benesuada
Thanks

Re:Mollisia
M. prunicola and M. rosae have long light brown hairs at margin and flanks,but I do not know that in your fungus. Good descriptions are f. ex. in Le Gal & Mangenot 1956-66, several papers in Bull Soc. mycol Fr. I remember there is also a description of M. benesuada (yes: 1960: 178).
Croziers: in herbarium material it is necessary to strongly squash the mount in KOH to which Congo red is added which stain the cell walls. Then the character should quit eeasily be seen.
Did you test the spores in KOH? because in dead material you may easily overlook guttules in the spores: In M. benesuada there are several distinct LBs at each spore end.

Re:Mollisia
My fungus don't have long and brown hairs at margin. Tomorrow I will take some photos and I will send it.
