Tricholoma terreum or similar?

[Brenzan]

I realize I should have taken better stock of the trees around, but I know there is a heavy conifer concentration in the woods I was in (hemlock, spruce, white pine).

 

Spore print is light but definitely white/cream. Notch in gills visible, gills serrated (age?). Cap umbonate when young.

I'll slice one of the younger specimens in half to see if the cap is inrolled, I remember that being a factor in ID.

 

Thanks in advance!
