Thanks, and a few more facts in favour of Tricholoma

Thank you all for the versions!
The gill attachment is, indeed, strange, but I’m inclined to attribute that to the fact that these fungi fruit very late in season, later than any other large mushroom, when temperatures are often near-freezing. It could have a slowing effect on their growth, leading to such distortions.
I’m thinking that our area could be the northern limit of their climatic “comfort zone”. The autumn of 2009 (a year later) was abnormally warm, and these mushrooms had more typical shapes.

Otherwise they match the description of T. columbetta, with mealy smell, non-viscid cap, and non-waxy, somewhat spongy flesh. Hygrophorus eburneus, the only late-season local white waxcap, is quite common here and looks very different, lacking, among other things, the interveining pattern visible on the gills of these fungi.

Looks more like Hygrophorus than Tricholoma.

My 2 cents

The cap looks easily like a trich, the stipe looks more like a trich, there is no evidence of past viscidity, and the only thing that suggests hygrophorus to me is the distance and intervenosity of the gills.
