discomycete in the Bavarian Forest

Lothar Krieglsteiner, 02-09-2021 23:11

found today east of Spiegelau, on decaying logs and twigs of Fagus. I found this repeatedly in the last years and tried to identify it as Dematioscypha richonis but I fear this was wrong. Is it better a Psilocistella? Who cann help.
Asci IKI blue, Calycina-type, with croziers. Spores about 6,5-7,5(8)/2,2-2,7(3) (not too many measurements). Paraphyses filiform, with few content. Excipulum prismatica, with long hairs without strongly thickened walls.
Best, Lothar

Re : discomycete in the Bavarian Forest

Re : discomycete in the Bavarian Forest

I give up for today, still only faults ...

Re : discomycete in the Bavarian Forest

Hi Lothar

perhaps Psilocistella quercina?

Re : discomycete in the Bavarian Forest

Hi Zotto,
I again fail to post my pictures.
Would you allow me to send you a WeTransfer - the picturer are already resized smaller.
Thanks!
Lothar

Re : discomycete in the Bavarian Forest

O.k., try it

Lothar Krieglsteiner, 03-09-2021 22:02

Re : discomycete in the Bavarian Forest

I already did :-)

Re : discomycete in the Bavarian Forest

o.k., you suggested Dematioscypha, but I still tend to Psilocistella quercina. There is no anamorph, the apos are flat exposed, the hairs not tapering. There is an article by Quijada et al. on this species.

Re : discomycete in the Bavarian Forest

Thanks, Zotto!I
I often found this in the Bavarian Forest and first I determined it as Dematioscypha, so I named my fotos so, still. But if you think this should be Psilocistella quercina, I am glad with this. I always doubted on Dematioscypha. Do you have the article of Quijada?
Yours, Lothar

Re : discomycete in the Bavarian Forest

here attached. But please compare it carefully, it is only a feeling. Anyway, P. quercina is a quite frequent apecies in my experience.

Re : discomycete in the Bavarian Forest

thank you, Zotto!
I will compare and then once again write here.
Best, Lothar

Lothar Krieglsteiner, 04-09-2021 21:22

Re : discomycete in the Bavarian Forest

Hi Zotto,
I compared and find no notable differences. So I think you are right. I am happy that an old mistake of mine could be cleared up.
Thanks again and best regards, Lothar
