Bernard DeclercqHello to everybody,

On an old collection on corticated branch of Platanusxhispanica I found 3-distoseptate dark greenish brown conidia 42-49x16-18 µm. I wonder if this belongs to the anamorph of Splanchnonema platani or something else.
Your help is welcome. I am interested in papers treating the anamorphs of Splanchnonema.

Re : Anamorph
Hi Bernard,

on a quick search in my files I found only one paper on Splanchnonema and anamorphs concerning S. argus on Betula (attached). Conidia look quite different.
But you may know this report: http://www.natuurbericht.nl/?id=9823

Martin

Re : Anamorph
Bonjour Bernard,
Ta photo n'est pas très explicite mais je suppose qu'il s'agit de l'anamorphe de
Splanchnonema platani : Macrodiplodiopsis desmazieresii. Je connais bien ces
deux taxons, je les ai souvent récoltés; très fréquents sur branches tombées
de platane de décembre à fin mars.
Amicalement
Paul

Re : Anamorph
Hello Bernard,

like Paul wrote, this is surely Macrodiplodiopsis desmazieresii,  the anamorph of Splanchnonema platani.
It is a very common species on twigs on Platanus.
I'll attach a further picture, too.

A nice work to the Pleomassariaceae (incl. Splanchnonema) by M.E.Barr you can find at Mycotaxon:

Best regards

Norbert

Re : Anamorph
Hi Martin, Norbert and Paul,

Excuse-moi, Paul, je réponds en anglais afin que tout le monde comprenne.

Thanks for your reaction.
I had already the Polish paper but thank you anyway, Martin.
In the mean time I have consulted Sutton (1980: 110-111) and the conidia presented there are strongly distoseptate, with one slightly tapering end. So, into my opinion, the conidia on my photo probably differ from those of M desmazieresii. Another cryptic species?

Bernard
