Hello.A Pleosporal symbiotic organism located and

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

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

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.
Zotto

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

... vielen Dank, Zotto!
Ist denn dann D. "faginea" die jodpositive macrospora - oder noch was anderes?
Viele Grüße von Lothar


super - alles klar, vielen Dank!
LG Lothar


only by the way: Andreas Foto ist from another colletion than my drawing.
Best, Lothar
