I was out foraging for Saffron Milk Caps and found what I think might be Mousy Tricholomas. Details:
Detached Gills/deeply notched (there are gills around the top of the stipe on some specimens upon very close inspection)
White-grey gills
Growing in pine forests between lithgow and bathurst
Easily broken stem
White spore print
cap is convex to flat with a slight umbo
