Re : Calloria
Dear Elisabeth
I guess it is something like Laetinaevia, but not sure at all.
you have nice turgescent asci, did you look for free spores recently shot? Are they non-septate inside the living asci?

Did you look at the margin for hairs? Surely it is not one of those with glassy hairs which sometimes have them only very scantily (Hyalopeziza raripila).

Re : Calloria
Pas de glassy hairs, peu de spores en dehors des asques, d'abord non septées, plus tard septées.

Re : Calloria
Merci! But an oil immersion photo of a turgescent ascus you don't have? 15-20 µm ascus width is very large, it woud mean that three spores may easily lie side by side in an ascus! You can't put a scale in your photos?

Now I looked in my database and arrive at Laetinaevia minutissima, a species I never saw. Seems to fit quite well.

Re : Calloria
Merci Zotto, nun reagieren die Ascusspitzen mit IKI rot. Meist sind die Asci bis 17µm (20µm eher die Ausnahme). Immer noch keine freien Sporen.

Re : Calloria
Oh, das ist aber dann problematisch. Hein hat eigentlich diese Rotreaktion gesehen, da er Lugol verwendete. Dann käme L. adonis infrage, die aber viele Öltröpfchen je Sporenende hat, zudem auf ranunculaceen spezialisiert. Jetzt weiß ich nicht weiter mit Heins Schlüssel.

Re : Calloria
Danke vielmals für deine Hilfe Zotto.
