Martin BemmannHi,
this one I found 3 days ago in a small park close to the Neckar river in Heidelberg. There are only Aesculus trees, so the twig I picked up from the ground shoud be of Aesculus hippocastanum.
With the naked eye there was nothing to be seen. With my hand loup I saw something like hairy orange dust. Rehydrated at home it looked like this:

I had no idea what it might be up to this point. Then I made a section and recognized that the main portion of this fungus is immersed in the substratum:

The outer width of the pseudothecium is 0,9 mm. The ostiolum is sometimes, when the ascocarp is mature, covered with a lump of hyphae mixed up with ejected spores.

And here some spores, 7 septa, (54-70 x 10-12,5 µm).

Any idea?

Best regards,

Re:Orange pyreno
Danke Zotto!
auch ich hatte den, wie der Finder Deines Belegs, erst mal für einen Discomyceten gehalten...

Re:Orange pyreno
Looks like a Tubeufia to me.

Re:Orange pyreno
Hi Gary,

Pseudotrichia viburnicola as it is described by Crouan/Crouan and identified as it in some pictures in the web and on Zottos DVD would perfectly fit to my collection. But apparently there are only very few specimen collected (mostly in France) that make up this species.
The genus Tubeufia is known to me by Amy Rossman's paper of 1987. But I did not find convincing features in the keys. Maybe due tu my greenness... ;-)

Thank you for your suggestion, that widened my field of view for further study.

Martin
