Asco on Myxo (Didymium)
Marja Pennanen, 10-07-2011 18:08
Hello folks,

I've been doing mostly myxos lately. So I picked some Didymium or Diderma last night and just studied it. The myxo is Didymium melanospermum, but there were some tiny, invisible ascomycetes growing on the surface of it, so no macrophotos are available.

The spores are small, 5-6x2 and asci about 50x4, propably hemiamyloid.

No idea even of the genus...

Hi Marja,
Your photo is a little too dark. You can use an open softaware like Photofiltre to work your image.
I don't know your fungus.

Re : Asco on Myxo (Didymium)
Ooh, thanks. I have Adobe photoshop limited edition and only crobed the photo.

Been searching in internet. Could this be Nectriopsis? Maybe Nectriopsis exigua? Just haven't found a description yet, just an old key.

Re : Asco on Myxo (Didymium)
Dear Alex,

thank you!

I'll check later if Mycologia, Vol. 65? contains a proper description of the species.
Nectriopsis oropensoides? could be another option. Should study some myxo-fruitbodies later for these, if there are some...

Marja

Hi Marja,
if your fungus is Nectriopsis orpensoides, then , hypal elements should be spinulose.
cordially,
Christian
