It looks pretty good for A. obscurata, but I think there are a few other clitocyboids that look similar – I really don’t have much of an opinion on these other than that they are dark omphaloids!

What’s wrong with Arrhenia obscurata?

Spores 6 – 8 × 3 – 4 µm, 4-spored basidia, clamps present, inamyloid. It looks close to Adolf’s photos & the habitat, time of year, and spore size looks good with mykoweb’s description.

I think you are right in your assumption that this is Arrhenia.

With something omphaloid, Arrhenia? I don’t really know.
