Phaeohelotium fulvidulum?

Fruit bodies were found on a dead Fagus leaf, were very short stiped and max 4 mm wide.
Spores in water measured 16 -22 x 3.5-5.0 micron. Asci (aboot 120 x 10 micron) without croziers. See pictures of ectal and medullary excipulum, spores and asci.
Could this be Phaeohelotium fulvidulum?
Kind regards, Jan

Re : Phaeohelotium fulvidulum?
I tend to confirm but would prefer to see living paraphyses with their contents and the dead ascus apex in Lugol.

Hello Zotto,
Herewith some extra pictures of paraphyses in water and asci in lugol. Hope this helps.

Re : Phaeohelotium fulvidulum?
The VBs in the paraphyses are fine, although I know them strongly refractive. The iodine photo is much too small, I wanted to see the shape of the blue ring.

Hello Zotto,
It looks to me that the blueing of the ascus top is weak if present at all. What do you think?

Re : Phaeohelotium fulvidulum?
Indeed, this is only the inner part of the thickening where two blue lines are visible. Not really what I expected. Together with the faintly refractive paraphysis contents I am a but sceptical. I am not really sure with the absence of croziers. If present it could be P. monticola.

Re : Phaeohelotium fulvidulum?
Bonsoir,
si je ne me trompe pas, P. fulvidulum pousse plutôt dans les endroits humides ou marécageux, personnellement je ne le connais qu'en tourbières en milieu acide, il est de couleur ocre.
P. monticola est plus jaune, plus vivement coloré, mais je ne connais que son sosie, P. epiphyllum, et ici il semblerait difficile de trancher, non ? On manque d'information sur la réfringence des paraphyses à mon goût.
If I'm not mistaken, P. fulvidulum grows more in humid or marshy places, personally I only know it in peat bogs in an acid environment, it is ocher in color.
P. monticola is more yellow, more vividly colored, but I only know its look-alike, P. epiphyllum, and here it would seem difficult to decide, wouldn't it? There is a lack of information on the refraction of the paraphyses in my opinion.

Re : Phaeohelotium fulvidulum?
There are some living paraphyses visible and they contain low-refractive medium-sized VB-guttules. P. epiphyllus I excluded as it has prominently multiguttulate VBs.
You are right. P. monticola is more yellow. It can be that the apical ring varies in P. fulvidulum.

Re : Phaeohelotium fulvidulum?
Oui, on voit quelques paraphyses, mais s'agissant d'un élément essentiel, en voir plus aurait été intéressant.
Yes, we can see a few paraphyses, but since it is an essential element, seeing more would have been interesting.
