Asco on Fagus cupules
Thorben Hülsewig, 30-09-2020 20:18
Hi there,

i found this asco on 25.09.2020 on a Fagus cupules.
At first I thought of an ombrophila, but in the meantime I am not so sure anymore. Interesting is that this species seems to have hairs on the underside of the apothecium.
Also the reaction of the asci on Lugol is weakly blue.
Any idea what it could be ?


best regards,
Thorben

Look for Hymenoscyphus (Phaeohelotium) fagineus

Hi Thorben

did you see any living paraphyses? Are the hairs also at the margin. A marginal section possible?

Re : Asco on Fagus cupules
Hi Zotto,

ich habe jetzt nur noch dieses Bild mit den Paraphysen, die auch mehrfach septiert sind.
Die Haare sind nur an den Marginazellen, leider habe ich jetzt kein Schnittbild, aber kann versuchen dies Nachzuholen.

best regards,
Thorben

Re : Asco on Fagus cupules
Of course H. fagineus is a good suggestion, I agree. About the hairs I canot remember if they may occur there.
