Pol DebaenstHello, Garden, Burgweg 19, Veurne, BelgiumOn 10/1
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
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

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)
Ich habe ihn in Somiedo leider nicht bewusst gesehen.
Gruss
Stip
