Summary:
Distinguishing characters are the white silky cap that becomes scaly and more or less flushed with yellow, the pruinose stem that is marginate-bulbed and pale yellow, and especially the persistent sweet odor, resembling that of the common sweet pea, (Smith(9)).

Cap:
2-4.5cm across, bell-shaped, becoming expanded and broadly umbonate, margin involute [inrolled] then gently rounded, finally almost flat; at first uniformly white, remaining so at center, toward margin becoming more or less yellowish or tinged with buff; dry, silky-smooth and almost shining at first (lubricous when thoroughly wet), "soon becoming more or less diffracted scaly, the scales with free ends" or even revolute [curved up], margin often rimose [cracked], sometimes deeply split when old

Flesh:
0.2-0.3cm thick off the disc, hard; white or pallid, unchanging with exposure, in stem hard

Gills:
"adnexed, in some almost free", slightly to broadly and deeply rounded close to stem, bluntly pointed at cap margin, rather close, 60-70 reaching stem, with 2 or 3 series of subgills of various lengths, gills moderately broad, 0.4-0.5cm broad, ventricose [broader in middle]; at first pallid, finally brownish olivaceous

Stem:
3.5-8.5cm x 0.25-0.7cm, base with a distinct marginate bulb 0.6-1.2cm thick, stem round in cross-section or somewhat flattened, frequently flexuous [wavy], solid; at first "cartridge buff" becoming "ivory yellow" to chamois, then when old more or less flushed with brownish or incarnate shades; somewhat shining, everywhere densely white-pruinose, conspicuously and broadly longitudinally hygrophanous-grammate

Veil:
no ring

Odor:
spermatic for an instant when flesh first cut, "then immediately becoming and long remaining very fragrant", almost exactly like a mixture of the odors of sweet pea and Convallaria majalis (lily-of-the-valley)

Microscopic spores:
spores 7-9(10) x 5.5-6.5(7) microns, merely angular to decidedly nodulose; pleurocystidia 43-58(60) x 10-16.5 microns, "subfusiform to sublanceolate, apedicellate, very thick-walled", "cheilocystidia of two kinds, one like the pleurocystidia in size and shape, the other smaller, clavate, thin-walled", 15-22.5 x 9-11 microns, in dense clusters

Spore deposit:
[presumably a shade of brown]

Notes:
Inocybe suaveolens is found at least in WA (Smith). There are collections from BC at the University of British Columbia and collections from WA and OR at the University of Washington.
