Identification: Tricholoma that blues at the base?

Found in a park in Seattle, Washington near a small pond. Spore print came out white. They only bruise blue at the very base of the stipe. They didn't blue any further than 1cm up the stem. They had a slight farinaceous odor.

Can't seem to find a match for these mushrooms. All the Tricholoma species which come close to a match have other features not present in these. The closest match i found bruises red/pink at the base not blue/blue-green.

Any help is much appreciated!!

 

Do the gills notch at the stem?

The gills run down the stem very slightly where they connect to the stem.

 

Maybe a psilocybe ? Still waiting to find one myself.

 

Psilocybes have dark spores, and Sovereign's spore print was white.
But I still have no guesses on this one.
You might want to try running it through Ian Gibson's Matchmaker, since it has some strong characters to enter:
