Could also be Russula norvegica (var. with red pileus). Pileus had a diameter of about 4-5 cm (2 inch), which is a little bit too large, both for R. nana ad well as for R.norvegica. Mycorrhiza possibly with dwarf willows (Salix herbacea, Salix retusa, Salix serpillifolia), Dryas octopetala, Bistrota vivipara…? Found well above tree line.
Russula nana, syn.: Russula alpina, Russula emetica var. alpina
Lat.: 46.44569 Long.: 13.64541
Habitat: upland grassland above tree-line, with dwarf Salix sp. species, on a mountain ridge, slightly north inclined slope, full sun, fully exposed to precipitations, a windy place, precipitations ~ 3.000 mm/year, average temperature 1 – 3 deg C, elevation 2.100 m (6.900 feet), alpine phytogeographical region.
Place: North Mangart’s flats, west of Mt. Travnik, 2.204 m (7.231 feet), East Julian Alps, Posočje, Slovenia EC

If you scan through Sarnari, or open “Funghi Alpini” by Jamoni (AMB) (covering that area) and when I add my own bewildering experience with those montane summer Russulas from the area, I know that any name on the cap color alone is most likely to be wrong. Not just wrong, but stupid wrong. Could be this, could be that is just as good as “I have not the faintest clue…” There are several reddish Russulas listed from montane areas of Southern Europe, including R. nana, R. chamitae/subrubens, R. Pascua, R. laccata, R. alpigenes and I swear they all look alike. Additionally, dealing with a single fruitbody is hopeless.
Still, the European Russula is fun to id and one is almost guaranteed to get somewhere. If you wanna go nuts come to the Rocky Mountains Colorado in the Summer and try to id that Russula mess there..
Amadej, you’re learning just like me – one step at a time – but consider that the study of Russula is not a casual matter, but a calling for life… Or, a bit more serious methodology, plus a collection of good literature. Otherwise one is not more likely to call it right than identifying some Amoeba although that there are a lot of people out there (including me) who think they know them well, but they don’t. Now, not to sound pompous, but people should get some sense that these species are much easier to eat than to id well.. “If you can’t beat them, eat them…”D.
P.S. Johannes, you want to id them down to Section. Not a bad idea. For starters, how many Russula Sections have you heard of? Next, what are the key features? If you do not know these answers then you can consider how much value there is in throwing some speculative infrageneric systematics. With Amanita it makes sense cause you’ve got somebody who kinda keeps the light on and has a site where you can check. But with Russula, it is harder. I try to do some informative studies on the Corts so that people can drill down a bit into the id abyss..
that we can classify Russula sp like this into sections of the genus but not to the species? instead of species?
In meantime Mr. Bojan Rot, http://www.gobenabovskem.si/ also proposed (among several other possibilities) Russula chamiteae but he also finds the information provided as insufficient for a firm determination.
Anyway, in my ignorance I thought that quite specific habitat, high elevation and limited mycorrhiza partners there would eventually suffice to come up with an acceptable determination. But evidently I was wrong. Next time I will be more thorough information provider. For the time being Russula sp. would probably be the most realistic ‘determination’.
almost looks like it could be of the Russula xerempelina group with those staining
and colors…but what do I know….
Amadej, I agree with Irene that it doesn’t quite look like R. nana. Your material reminds me of some of the mildish, montane species we see in the Balkans — the Italian sources cover them pretty well. But that will require more analysis. Anyway, the spores shot mounted in water shows no useful diagnostic information. You know that for Russula you need to show the ornamentation with Melzer’s and max magnification — something like that:
I do not recognize this as Russula nana. It has a bright red cap, not purplish like this one.
what color were the spores? white?
