Summary:
Features include a moist, pale buff cap, notched, crowded, narrow gills that are white to pale grayish yellowish-pink, a stem that is pallid to grayish white with a purple tinge, a colored spore deposit, and microscopic characters.

Material was examined from OR, CA, CO, MI, and NY, (Bigelow(5)). Collections from BC are deposited at the Pacific Forestry Centre. There are collections at the University of Washington from WA, ID, NY, and (as Tricholoma personatum) from NC. It also occurs in Europe.

Odor:
none (Bigelow), pleasant (Hansen), pleasant, aromatic, (Schalkwijk-Barendsen)

Taste:
mild (Bigelow), pleasant (Hansen), pleasantly nutty (Breitenbach)

Microscopic spores:
spores 4.5-7 x 3-4 microns, elliptic, verruculose [finely warty], inamyloid, ornamentation cyanophilic; basidia 4-spored, 17.5-25.5 x 5.5-7 microns; [pleurocystidia and cheilocystidia presumably absent]; clamp connections present, (Bigelow), 6-9 x 4-6 microns, (Hansen), spores 4.5-7 x 3-4 microns, small warts, inamyloid, (Butler), spores 6-8.1 x 4.1-5.2 microns, elliptic, finely punctate to finely verruculose, colorless, (Breitenbach)

Spore deposit:
"pale vinaceous fawn" or paler, (Bigelow), rosy peach color (Schalkwijk-Barendsen), grayish or brownish pink or paler, (Butler), cream-yellow with an orange tint (Breitenbach)
