Hi everybody,I found this very large Trematosphaeria species? on many branches buried in the riverbed of the Elbe last weekend. Perithecia immersed, diameter up to 1.2 mm, wall thickness basal up to 55 µm. Asci up to 143 x 15 µm, IKI negative. Spores mostly 7-septate, endcells slightly paler than the others, in the 4 middle cells large oil-drops plus eventually some smaller ones. Spores at both ends with hyaline appendages (with blue ink), (33-39) 35.5 x 9.18 (8.5-11) µm. Could it be Trematosphaeria biappendiculata Kaz. Tanaka, Y. Harada & M.E. Barr, Fungal Diversity 19: 149 (2005)?
Regards, Maren

Re : Trematosphaeria biappendiculata?
Good evening Maren,
I think I already encountered your fungus that I collected once on submerged wood in western France. I think it is slightly different from T. biappendiculata by its immersed ascomata with a crest-like apex, peridium composed of smaller cells and ascospores with more septa. No doubt they are closely related, to me it might be an undescribed European counterpart of the Japanese taxon.
Cheers,
Jacques

Hi Jacques,
thank you for your opinion. An undescribed species would explain why I could not find it in any key. The japanese species was the closest I could find.
