Chlorencoelia torta or not?

Good evening forum members,

The fruiting bodies were found on a fallen branch, probably willow, lying in the mud in a willow swamp. The fruiting bodies break through the bark, diameter of 3 to 8 mm. color of olive yellow to brown. I was convinced that it is Chlorencoelia versiformis but the dimensions of the spores and asci are much smaller than indicated in the description of J.R. Dixon in Mycataxon. It would then be Chlorencoelia torta but I get almost no blue reaction in Melzer. Can someone put me on the right track?
Thank you very much!

spores: 7,23-9,21 x 1,89-2,99 µm
asci: 39,97-53,15 x 4,83-6,38 µm

Re : Chlorencoelia torta or not?

Chlorencoelia is in fact similar, but I think this could instead be Encoelia glaberrima. Did you try to better see the paraphyses? Living paraphyses of Chlorencoelia contain conspicuous yellowish vacuolar bodies, while E. glaberrima not.

Re : Chlorencoelia torta or not?

Dear Zotto,

it was hard to make a "coupe" and to distinguish the paraphyses, here are some photos.
Between the asci I saw yellow gel-like substances. What I took for a parafyse is branched.
Thank you in advance to looking at the photos.

Greetings,

François

Re : Chlorencoelia torta or not?

There is some problem with the sharpness of your photos, but the last one is good enough to see that the apical cell is without yellowish VBs but instead covered by yellow exudate. Both this contradicts a Chlorencoelia, in my experience.

So possibly Encoelia glaberrima.

Re : Chlorencoelia torta or not?

Thank you very much Zotto. The last pictures are taken with a magnification of 1000 and then one can see the limitations of my microscope.

Friendly greetings from Flanders,

François
