Durella on Fagus
Lothar Krieglsteiner, 16-05-2018 18:01

... unfortunately, my microscope camera broke down today, so I can only post a bad sketch.


I think it is a Durella from the Bavarian forest, on a decorticated area of a lying Fagus-log, initial phase.


With an old key of Zotto I come to Durella "faginea".


Two questions now:


1. Is my suggestion correct or totally wrong - and, if it is correct:


2. Is there a legitimate name for this "..."-taxon now?


Thanks and best regards, Lothar

Re : Durella on Fagus
Hi, Lothar,

I would suggest D. macrospora but I don't know D. "faginea".

Schöne Grüße
Gernot

Hallo Lothar,

da bin ich auch bei Gernot. Hatten wir hier schon an Malus, Mikros finde ich momentan nicht.

LG Peter.

Re : Durella on Fagus

Hello Gernot and Peter,


thanks for your opinion - it is surely a strong argument if your opinion is the same :-)


In Zottos old key D. macrospora is keyed as iodine-negative - but in his folder I found a specimen "Durella macrospora IKI+", so this may be variable (?). Furthermore, the spores are a little bit small for macrospora (?). Maybe this is variable, too.


We will see if Zotto shares his opinion with you - if yes, I will be fully convinced :-)


Best regards and thanks again,


Lothar

Hi
yes, and the amyloid form of D. macrospora seems more frequent. So far we have 3 sequences of the amyloid but none of the inamyloid form.

Re : Durella on Fagus

Hello,


I found the same species today and sent Zotto a (private) mail before I looked in the forum here.


So I can add a few fotos here, though not the best quality.


Also I found an anamorph which I think belongs to this Durella, but this originated from another Fagus tre.


best regards,


Andreas

Re : Durella on Fagus

... vielen Dank, Zotto!


Ist denn dann D. "faginea" die jodpositive macrospora - oder noch was anderes?


Viele Grüße von Lothar

Hello,


just adding a foto of the collection mounted in Barals solution, showing the amyloid ascus pore and the exsudat in the hymenium.


best regards,

Re : Durella on Fagus
o.k., and the lumps of exudate seems what I mentioned above. So no doubt D. macrospora s.l.
