« < 1 2 3 4 5 > »
unclear discomycete from Southwest Alps (France)
Lothar Krieglsteiner, 09-07-2017 14:19
Lothar Krieglsteiner

found at 27.6.2017 near St. Anne (w. St. Etienne de Tinee) in the National Park of Mercantour (Southern France), in Abies-forest at about 1600 m NN, at a moist spring, on dead remains of likely Petasites albus.


I have no good idea about the genus - the paraphyses without a lot of content, together with the excipulum of prismatica and the big spores. What is most peculiar: the excipular end-cells are distinctly warted! I do not know such a disco.


Can somebody help?


Best regards from Lothar

Hi Lothar,
it baets me too, spores seem to become a bit smokey coloured too and a apical apparatus looks like Rutstroemiaceae.
perhaps Zotto has an Idea

Hi Lothar & Stip

The ring has some similarity with the Sclerot.-type but it does not diverge apically. No, this is my Pezoloma herbicola. Also this species is under work, we have now a sequence (by Michel) which actually fits the genus Pezoloma.

I still cannot believe that this species should be undescribed. We had it also In Somiedo recently.
Again I would be glad to include your collection data.

Sorry, die Funddaten sind ja bereits recht präzise. War das ziemlich nahe bei St. Anne? Die 1600 m sprächen dafür.

Hi Zotto,


thank you for the determination of "Pezoloma herbicola" - I did not find the species by now.


The find data:


Nationalpark Mercantour (Frankreich), sw. Saint Etienne de Tinee, oberhalb von Saint Anne, 1807 m NN, N44°13'30.78" E6°51'18.14" (GPS-Daten am Bild - ermittelt mit Geosetter)


I hope that fits :-)


Best regards from Lothar


P.S. Although I looked at black resin I did not find a Lilapila - the only harvest was Sarea difformis and once a Lachnellula (I did not take the sample so I cannot say if it was resinaria or calycina)

Ahja, das wäre dann auf 1785 m, 1.5 km SW von St. Anne.

Thanks Zotto,
Ich habe ihn in Somiedo leider nicht bewusst gesehen.

ich will heute meine Bilder in Google Drive einordnen, also unter herbicola. Dann kannst du sie dort anschauen.
