Pyreno, staining substrate turquoise
Andreas Millinger, 10-04-2025 21:52
Andreas MillingerBonsoir!

I'm new to the forum and would kindly ask for help with this species.


Found on soft deciduous wood near a small stream in austrian hills, 700 msm.
Fruitbody is of soft leathery consistency when wet.
Staining substrate turquoise.
Distinctive spores measure [26.2-29.7] x [9.4-10.8] Q = [2.5-2.9] N = 22
Breaking apart, when ripe.
Can I see a germ slit?
Added collages made by my daughter.


Thanks a lot in advance!

Re : Pyreno, staining substrate turquoise
Hi Andreas, welcome to the forum.
For a first post, you strike hard!
I came across a similar fungus, also on the banks of a stream, on Robinia wood, which just differs from yours by thick slit-like ostioles and slightly smaller ascopores 18.5-22.5 x 8.5-10 µm with curved germ slits in each cell (photo attached), a gelatinous sheath and not breaking apart.
All I can say about it is that it is a Dothideomycete with bitunicate asci and ascospore morphology suggests affinities with Delitschia. I suppose it might be an undescribed genus because such a turquoise green stain of the substrate is much uncommon. Unfortunately the collection could not been cultured nor sequenced.
I wish you to go further than me!
Best,
Jacques
