It does not turn yellow

upon drying unlike H. discoxanthus which was long included into H. cossus. We need more information on this. If it is sticky or dry, if with oaks or beeches, and best would have been a voucher specimen. H. penarius can be distinguished by its cuticle from other similar white and rather dry species.
But now back to work. I have two extremely difficult finds to determine :)

H. eburneus var. quercetorum is what we call cossus nowadays.

Then I would go for

Hygrophorus eburneus var. quercetorum or H. penarius. If smell is mealy like mentioned then it most probably is H. penarius. I just wonder about phenology. I only know eburneus var. quercetorum coming thus early in the year.

Yes, Hygrophorus

The gill attachment with a fine white “rim” around the stem is typical for several Hygrophorus species, also the dotted surface on top of the stem.
A Tricholoma would normally have more emarginate gills.
Here is a site with what I trust is the true Tricholoma album:

What about size and slimyness of this specimen?

Maybe Hygrophorus?

Hi there
It seems that stem is pustulate and somewhat sticky, recalling Hygrophorus penarius. Otherwise T. album (in the sense of Funga Nordica) seems a OK name. This species grows (exclusively?) with oaks, and have a complex smell, uuslally with distinct honey components.

T. album seldom is completely white as you can see in the German name “Strohblasser Ritterling”. But color depends on age and weather. Do you have any clearer photos? And I have to remind you once more that it is high time for a microscope if you want to get further in your studies. There are a mere few hundred species which you can learn to distinguish by the naked eye when you have years of experience. Everything else is impossible to determine this way especially when you are more into it and the fungi are getting smaller :)

Also, gills are less crowded in Album than in Columbetta it seems

T Album

Looks more like T album, as it is completely white, smells bad and does not have stripes on cap.

So it is a Tricholoma for sure.

But Tricholoma columbetta does not really smell bad. It has a faint smell like flour though. Maybe it is old. But also look for T. album, pseudoalbum. Their smell is really bad but also can have a tinge of flour to it.

Gills are spaced, rather narrow. I wouldn’t know about waxy. Smell is rather strong, not so pleasant, floury.

Habitat would be okay.

I usually find this with oak or beech and rather early in the year.
But I will not rule out Hygrophorus – are the gills rather waxy and spaced or thin and rather narrow? What about smell? Another option could be Tricholoma album although I do not believe it to be. Blue staining in T. columbetta is a good feature but may not always be observed.

In mixed hardwood forest, between leaves
No traces of blue stains – flesh stayed white, immutable when broken
