Hello again,this finding seems to be an inoperculate contrary to my mysterious Pezizales, which is perhaps somewhere between Boubovia and Sphaerosporella. It grows on wood of hardwood (Quercus?) and forms brownish-ochraceous fruitbodies which are 2-5 mm broad. There is no stem.
The microscopic features are:
Spores fusiform, very variable in size and form, with a thin gelatinous sheath, hyaline, permanently with 2 bigger oil droplets, 14-20x4-7µm. Asci with 8 spores, short stalked, without croziers, 110-130x8-10µm. Paraphyses with strongly refractive guttules, especially in the apical part, septate and branched. No hairs. Ascus apex in Lugol blue.
If more information is needed, tell me, I have the finding right here in a plastic box ;)

Re : unknown Helotiales?
Hi Kazyua :-)
very fine presentation! Clearly a Hymenoscyphus s.l. (Phaeohelotium). I assume you are sure there is not long stalk hidden in the substrate (that is sometimes overlooked).
The spores do not look very variable. Are you sure with the absent croziers? I would be surprised but this is very important. I thought it could be H. epiphyllus or H. monticola, but I am not very happy with my idea.
A section of the margin and flanks would perhaps also help

Re : unknown Helotiales?
Hi Zotto,
I tried to find some croziers but I did not have success with it. I also thought about a Hymenoscyphus, the size and shape remembered me on H. epiphyllus, but I know this specimen more yellowish...
I will try to make some more photos if there will be the time for it.
regards

Re : unknown Helotiales?
Hi Kazuya
when looking again at your fungus I am sure that it is Hymenoscyphus fulvidulus. This species is somewhat variable, from brownish to grey, but the features all fit including absence of croziers and strongly refractive VBs in the paraphyses.

Hi Zotto,
many thanks. I didn't check this species again, so I am sorry that I cannot give you some more details.
