The pileus varies in color as does the pileus of Russula 

 v a r i a t a Banning and Russula squalid a Pk. It is very 

 close to the latter, from which it scarcely differs except in its viscid 

 pileus, its late occurrence, its lamellae and flesh not changing color 

 where wounded and specially in the color of the spore print.
