It should be Entoloma catalaunicum, not catalunicum..

I’d be happy to support Entoloma catalaunicum. It was first described from Spain (Catalonia), and I find it regularly on Gotland, Sweden, an island with calcareous and dry localities (heaths and roadsides) that can get very hot during the summer. It is the same kind of climate as in some arctic/alpine limestone habitats, and they share several similar mushrooms (like some earthstars and Inocybe species).
The stipe is, as you point out, grey, sometimes with a greenish blue hue at the base. I have never seen much other pink colour there than discoloration from the spores..

You’ll find both Singer’s original description as well as a more comprehensive one by Noordeloos here:

pink on the upper stipe in the second photo. It may be spores caught in the fine grooves. But then, the older observation description that says the upper stipe of one of the candidate species is “becoming pink” may be referring to the same phenomenon.

I was looking at Noordeloos’ picture for E. catalunicum (and this is the mushroom I intended to draw a comparison to), but it was linked off a page that included E. callichroum and I swapped the names.

I have a copy of Noordeloos’ treatment of E. catalunicum in Funga Nordica in front of me as well as my microscopic notes and drawings and it appears that due to the bluish cap margin, and presence of cylindrical to clavate cheilocystidia, E. catalunicum is a much better match than either of Largent’s pink taxa L. subrubinea and L. rosea.

However, all of these taxa are supposed to have pinkish stipes or distinctly pink stipes, and this collection had an evenly grey stipe. Still, the closest is E. catalunicum which is described as having a half-gray stipe becoming pinkish over the upper half.

Funga Nordica mentions an arctic habitat for E. catalunicum, but I couldn’t find Singer’s original description.

The spores are a good match for E. catalunicum.

This one is cool, I don’t think I’ve seen this one before…
