brown Peziza from Norway

... collected at 20.6.2015 in the National Park of Dovrefjell - wayside on the ground unter Betula and Pinus. The year 2015 had a very long winter, and so it would be possible that "snow fungi" are present, as the most common fungus we found at this journey was Gyromitra esculenta (atypically late).


I have some problems with characters and so am not sure about possible results.


Fist: The spores (they measure about 18-19,5/8,5-9,5 µm) seem to be minutely ornamented to me, finely punctate. It is difficult to bring this "onto the foto" - and there seems to be little staining with CB. Anyway, a trace of ornament ist present as I think.


Second: I am not really sure about the structure of the excipulum. Behind (under) a layer of quite large cells there is a layer that I can only difficultly interpret if it is a "middle textura intricata" or not.


So - as there are a lot of brownish Pezizas I have no security about possible determinations. I imagine P. pseudovesiculosa (but the apothecia were not too large), P. ninguis (I do not find the paraphyses to be monliniform) - or perhaps P. granulosa if I consider the spores to be smooth.


Can somebody provide me with a hint.


Best regards, Lothar


P.S. The first microfoto was taken after the find, the rest today

I am thinking of P. arvernensis, but whether the paraphyses may be such guttulate I wonder, also I know this only in beech-oak forests.

Hi Zotto,


thank you for your response. Yes, P. arvernensis is in the key (of Hohmeyer 1986 that I used) next to P. pseudovesiculosa - and the affinity to Fagus is considered important. But - why not without Fagus. On the other hand, I find the specimen a bit dark for arvenensis (that I usually know at sites where Fagus logs were freshly cut).


Best regards, Lothar

Hello Lothar,

to simplify the possibilities a bit, P. pseudovesiculosa and pseudosylvestris are now considered synonyms of P. arvernensis. https://www.researchgate.net/publication/313793699_Morphological_and_phylogenetic_clarification_of_Peziza_arvernensis_P_pseudovesiculosa_P_pseudosylvestris_and_P_domiciliana

Hi Viktorie

as you probably have the article I would be glad to receive it. In the abstract stands "monophyletic", not synonymous.

Hello Viktorie,


this is in fact simplifying :-)


So I am much more lucky with the determination P. arvernensis.


I just requested the paper on Research Gate and look forward to read it hopefully soon. As far as I get it, I will send you, Zotto, a copy (if not Viktorie already does this).


Thanks again to you also, Zotto!


Best regards, Lothar
