Gills: free, broad up to moderately broad, close up to crowded, white up to whitish or cream-white.
Stalk: 5-9cm long, 0.8-1.5cm thick and enlarged toward base, brownish-gray, uneven as somewhat tiny scabers, indistinct fibrous.
Habitat: rare kind, small groups or single scattered at the old partially rotten deciduous stumps or trunks (mainly rotten birch wood) in pine-tree forest with some birches and aspen.
Edibility: edible.

Recognized by sight: Gills with dark edges.
Used references: As far as I can tell, this species name is used for both European and North American species.

Recognized by sight: note appendiculate margin to upturned cap. this may well be something unique. Karakhstan is closer to Russia than Europe!

Yes, the Asian, European and North American “P. atromarginatus” are all the same species, although there are at least some lookalikes in North America. The molecular phylogenetic work and keys in Justo et al. (2014) are very well done and it’s probably the best paper ever written on this group. I highly recommend checking it out.

P. atromarginatus was also originally named from Europe IIRC.

The “appendiculate” margin looks like an inrolled and slightly rimose margin to me. I’ve seen this before in P. atromarginatus and P. cervinus in the US.

the margin tissue is probably not significant. The dark gill edges more so.

I really am not familiar with the Pluteus sp. of Kazakhstan! So I was being conservative.

Can it really be the same sp. with that broad of a range, tho?
DNA determined?

I hardly trust some of our NA focused specific IDs. Kinda sorta maybe not.

Debbie, I don’t see…

an appendiculate cap margin. The margin on the upturned cap looks a bit ragged, but I don’t see any type of material that looks like it came from a veil. Other stuff on the caps looks like bits of substrate.

Thank You! I agree

The problem with the name of common completely white kind (sometimes abundant).

Using the keys to both the Western Palearctic and Eastern Palearctic in Justo et al. leads to an ID of P. atromarginatus for this.
