yellow-green discomycete on living Carex
Khomenko Igor, 12-01-2021 06:29
Khomenko IgorHi,
I found this discomycete in two instances in September on the living roots of Carex.
If someone can point me to the right genus.

Apothecium was up to 3.7mm.
Asci croziers(+), IKI+b. The apical apparatus is Hymenoscyphus-type.
Ascospores 20 - 30 × 4.4 - 5.3 µm

Thanks you,
Igor

Hi Igor

I think this is Phaeohelotium epiphyllum, although the spores are a bit long.

You did not study the excipulum at flanks?

Also the second sample I think is the same. Here the living paraphyses are missing (the best difference against P. monticola).

Re : yellow-green discomycete on living Carex
Thank you Zotto,

I didn't know that it could be parasitic on living plants.
I didn't do section because I have troubles understanding what I'm seeing.
I collected Phaeohelotium epiphyllum near both locations. Near the first (#461) on a big rotten log and near the second (#461b) on Fagus and Acer leaves. In both cases they were bright yellow, with shorter spores and fitted well with the description.
Yes, the both specimens were the same. For the second specimen I also did in Congo Red, so I could see croziers better.
I head about P. monticola, but haven't seen it yet. It was a good year and I saw a lot:
Hymenoscyphus albidus, H. imberbis, H. fructigenus, H. kathiae, P. menthae, P. fulvidulum, H. scutula, H. subferrugineus,
maybe P. fagineum and a few more I can't id yet or uncertain.
For instance like this gorgeous H. vacini (#400) on Acer petioles and other leaves:

Re : yellow-green discomycete on living Carex
H. monticola cann be excluded from the paraphysis contents, at least European specimens (I remember it is an American sepcies).

Yours could be something different - DNA would show.

You say H. vacini but this is certainly not. H. vacini has short stipes and a met-like black exterior, also no yellow disc.

Thank you Zotto,
It looks like it is more complicated than I can handle right now.
