Hello everybody,I found this Pyrenopeziza? species on Phalaris arundinacea last weekend.
Apothecia 0,5 mm in diameter with inrolled margin, whitish-hyalin, sessile.
Outer excipulum hyaline, textura angularis to textura globosa,
with difficult to identify, hyaline margincells, slightly clavate at the apex, up to 30 µm long.
Paraphyses simple, up to 2 µm wide at the apex without content. Asci with croziers 39-42 x 5 µm, IKl+ blue (Calycina-type), spores hyaline, clavate, oil 0-1, (9-11) 9,88 x 2,57 (2-3) µm.

Hello Maren,
I do not think this is a Pyrenopeziza. Unfortunately, the views of the paraphyses are rather blurred, but I suggest they contain vacuolar bodies. So, it could (should) be a Mollisia. Maybe, it could be M. hydrophila which has similar spores and appearance. But surely, more competent people will write there opinion.
Yours, Lothar
it was very difficult to get a clear picture of the paraphyses at all, this one is with 500x.
There maybe some vacuolar bodies present, but none refractive. I don't think it is M. hydrophila because there are no crystals in the medulla.
Regards
Maren
I also think it is a Pyrenopeziza, the paraphysis contents are now clear.
On monocots I have nothing with such clavate spores, however.
I assume this is a rather sparse collection? All apos looking like this?
Zotto
ich habe an einem anderen Halm noch eine Gruppe mit Fruchtkörpern fotografieren können. Pyrenopeziza psilocistelloides Baral sp. prov. kann es wohl wegen der septierten Randhaare nicht sein, oder?
Gruß, Maren
Also das war schon deutlich haarig, und ob es wirklich eine Pyrenopeziza war? War auf ?Deschampsia aus Gerardmer.
