Aquatic Pyrenomycete with spores 90 x 18 µm

Dear collegues,


during a research on teleomorphs of aquatic ascomycetes we came across this pyrenomycete today, on submerged log of Fagus.


The macrofoto is quite bad, sorry! But may be it is still a little bit helpful. The perithecia are single, black and nearly superficially seated, in small group but never toucing one another.


Spores multicellular, first hyaline than brown, becoming 8-celled, with an hyaline appendix (not always visible), appr. 90 x 18 µm


Asci bitunicate (?)


Anyone an idea?


Thank you very much,
Andreas

Hi Andreas,

looks like Trematosphaeria hydrela.

Best wishes,
Gernot

ja- Trematosphaeria hydrela. Gernot war schneller :-)


Nicht selten in Bächen, fand ich früher, als ich z.B. in Rhön und Rothaar-Gebirge an solchen Stellen suchte, häufiger.
