Jason KarakehianHi does anyone have a digital copy of Raitviir A (
I found this one on Quercus sp., I think. I first throught it could be Alnus sp. because it lay in water in a "Erlenbruchwald", but there were also some oaks. The wood had no longer bark.
The fruitbodies are to 0,2 mm wide. The spores are big with 41-47 x 9 – 11 µm brown, with 5 septa, the cells on the ends are brighter than the others. The 3rd one slightly larger. Asci IKL negative 153-180 x22-25 µm. Paraphyses thin up to 1,5 µm.
Thank you for your help.
Regards Maren
this is Trematosphaeria wegeliniana, an aquatic species occurring on submerged wood or wood that has been submerged for long before being found on river banks. The ascospore wall is finely longitudinally striate but not always easy to make out.
Cheers,
Jacques

Trematosphaeria wegeliniana
We'd found this species only once in Saxony (N. Heine), never in my region or somwhere else. You also have to know that I am working on aquatic pyrenomycetes only since last year october. I think T. wegeliniana is not frequent. For more pictures, look for it in the ascofrance database.

Maren, take care if you begin to focus on such fungi you will forget about others!
Cheers,
Jacques
Found it in Deux-Sèvre in France and in Lozère. Both with ph<7. What about water's ph where you found it, Maren, Björn and Jacques ?
Yannick
thank you all for your comments.
With a short fungi-season and dry summers in Northern Germany I will probably look for more of these fungi. ... they have such beautiful spores :).
Yannick, I checked the ph in the water today, it is rather acid with 5,8.

Hi friends,
Never found in my calcareous country. I've only one data from Mellasco (79 =Deux-sèvres, cf Yannick's data).
If it could grow in my land, I would have found it.

Good luck with aquatic ascos to you all!
