yellow discomycete on herbaceous stem
Lothar Krieglsteiner, 25-07-2020 18:40
Lothar Krieglsteiner.. in the Alps (exact findplace can be asked), montaneous area near small rivulet, 26.8.20. The asci are about 28-35/5-7 µm large, have croziers and react blue in IKI (Calycina-type). The spores are about 7-12/2, with oil about 1. Who does have an idea?
Best, Lothar
P.S. Together grew another discomycete, possibly an Olla - it was not examined.

Re : yellow discomycete on herbaceous stem
In some way this should be psilachnum rubrotinctum. Did you test KOH?

Re : yellow discomycete on herbaceous stem
thanks, Zotto, for your proposal. I did not test KOH -by now I was only awarre to do this in the case of mollisiaceous fungi ...
Best regards, Lothar

Re : yellow discomycete on herbaceous stem
But you know P. rubrotinctum? Often on Filipendula. I must correct myself, that species turns pink with ammoniak rather than KOH. I have it in my Cistella folder, not in Psilachnum.

Re : yellow discomycete on herbaceous stem
no, by now  I never found Psilachnum rubrotinctum. I will try ammonia - but it will take some time. Thanks again and best regards, Lothar
