The spores

fit well with Entoloma formosum (Funga Nordica says 9-14 × 6-9 μm, heterodiametrical, 5-9-angled).
Most pictures show them with a little more orange caps, though. I’m not sure if the colour here is within the range of that species. It’s usually more slender and long-stemmed too.
There are so many species described, that it’s very likely to be another Leptonia..

Leptonia formosa is an interesting ID

…and a new species for me.
These did have scales on a good portion of the cap and were very striate.
The one somewhat minor problem are the spores, which according the Kauffman write up are 10-12 X 6-7 microns. These seemed a little larger but I’m not sure of the protocol in measuring these highly angular spores with a large apiculus.
