Stipe pruinose all way down as in Inocybe mixtilis, but the size of spores is larger than in I. mixtilis and fits I. praetervisa that should be pruinose only in the upper half of the stem.

Could use the “Inocybe praetervisa group” name on MO

I asked Brandon Matheny, who works on Inocybe. This is his reply from 2012-09-27:

“Yes, I. praetervisa has an entirely pruinose stipe, but the species is polyphyletic. Compare with I. straminipes and I. salicis-herbaceae (which based on memory and molecules is not a strictly alpine European species).”

there is something called Inocybe xanthomelas, described with a pruinose stem.

A book by Rea 1922 (British) says apex pruinose. The earlier Stuntz ca. 1978 PNW key to Inocybe says the stem is pruinose at top. But in the Matheny 2002 version of the PNW key, Inocybe praetervisa keys out near Inocybe mixtilis under a key choice that says stipes are pruinose the entire length. So I wonder if that is an error by Matheny or a correction of earlier descriptions.
