Discomycete on Limonium vulgare
Maren Kamke, 12-10-2013 21:17
Maren KamkeHi everybody,

on the coast we found an ascomycete on Nimonium vulgare.


Apothecia 1,2 mm wide, dark grey with lighter margin, sessile. Spores hyalin cylindrical to ellipsoid, (16-20) 18,2 x 4,9 (4,5-5) µm, filled with guttules to 75 %. Asci 80x11 µm, Ikl porus-reaction blue to violett (hymeniscyphus-type?), with croziers. Paraphyses clavate apical up to 4 µm. Margincells inconspicuous.


I hope you could help me because I can't make more examinations, there ist no fungus left :(.


Thanks


Regards Maren

Re : Discomycete on Limonium vulgare
Hallo Maren

habe leider nichts auf Limonium.

Aber für Caryophyllaceae mit solchen Sporenmaßen gibt es:
Laetinaevia colobanthi (S-Amerika) und
Pyrenopeziza capsulicola Petrak, auf Silene.

mehr kann ich wohl kaum helfen. Etwas erinnert es auch an eine Spilopodia. 
Leider sind die Paraphysen nicht recht klar.

Re : Discomycete on Limonium vulgare
Hi Zotto,
vielen Dank.
Ich hatte auch schon an eine Pyrenopeziza gedacht, aber nichts passendes gefunden.
Cyberliber ist im Moment nicht erreichbar und ich habe bisher keine Literatur zu P. capsulicola? gefunden.
Hier noch zwei Paraphysenbilder. Leider war der Pilz schon so vergangen, dass wenige Einzelheiten festzustellen waren.

Gruß Maren


I had already thought of a Pyrenopeziza, but found nothing suitable.
Cyberliber is not reachable at the moment and I havn't found any literature to P. capsulicola.
Here are two pictures of the paraphyses.

Re : Discomycete on Limonium vulgare
Cyberliber geht wieder:
Sydowia 1: 32-34

But ecologically it is quite different, growing on the uppermost peak of the alps.... :-(

Re : Discomycete on Limonium vulgare
Hi Zotto,
yes, the ecological environment is rather different ;).
I managed to find some remains onthe stalks and could make some clearer fotos of the paraphyses, maybe this helps. The spores get 1-septate with age.
Otherwise get's the fungus a big cf.

Re : Discomycete on Limonium vulgare
Good, this will help at least for the future. I conclude that the paraphyses are without any VBs, so a Pyrenopeziza seems possible. But Spilopodia would still be another option.
