Buckwheat PeteHello, I'd like to ask about this older specimen:
Aquatic ascomycete.

A cerebriform ascomycete sprouting scattered on the surface of a trunk submerged in a clear stream.
Ascomata measuring up to 4 mm long and 2 to 2.5 mm wide, I was particularly struck by how tough and tenacious these ascomata were.
Very thin conidiophores arranged parallel in a palisade-like pattern produce globose conidia with a large lipid droplet inside that occupies three-quarters of the spore.
An amyloid reaction is observed from the base to the middle of the hymenium with Melzer's Reagent.
No apparent reaction to KOH.
Some of the images show clusters of these supposed conidia, which I wouldn't completely rule out asci.
These presumed conidia measured in water:
(3.6) 3.8 - 4.4 (4.7) × (2.9) 3.2 - 3.8 (4) µm
Q = 1 - 1.3 (1.4) ; N = 40
Me = 4.1 × 3.6 µm ; Qe = 1.1
I admit I don't even know where the air is coming from.
Any opinions would be welcome.
Thank you very much in advance.
Best regards.

Re : Aquatic ascomycete.
Hi Josep
by accident I looked again in your thread. What a shame that I did not realize this being an Ascocoryne! Now the things are clear thanks to your DNA analysis.
I annotated your tree below but could not name all clades because GenBank is presently out of order.
As your sample is identical with OP023244, I conclude that it is also identical with a Polish sample on Salix not in GenBank (BRA CR32406), which had both conidiomata and apothecia, the latter regrettably overmature. It is so far the only case with apothecia within this "laurisilvae-clade".
A. laurisilvae is only known from its anamorph. It looks very much like yours, despite the genetic distance (see below).
Do you have any idea about the substrate? It looks like a deciduous tree. Do you have the wood to check its anatomy?
I would be pleased to receive the collection data, also the sequence and its ab1 file. And it would be great if we could use your photos in our work. Do you have a scale for your pics?

Very strange is the amyloid reaction, we did not see that in any anamorph of Ascocoryne!
