Summary:
Features include 1) a dry, fibrillose scaly cap that is cream-colored to isabelline, 2) adnexed, close, narrow whitish gills, 3) a stem enlarged towards the base and cap-colored or paler, 4) smooth, elliptic-amygdaliform spores, and 5) microscopic characters. The description is from Kauffman(4) except where otherwise indicated.

Cap:
3-6cm across, subconic, then bell-shaped - expanded, umbonate, margin decurved [downcurved]; cream-colored to isabelline; dry, fibrillose-scaly at center, becoming long-rimose [long-cracked] toward margin, (Kauffman), cream color or at most dingy yellowish or straw color; silky, soon becoming scaly at least at the center, not lubricous when wet, (Stuntz)

Gills:
adnexed, close, narrow, broader near margin; whitish-avellaneous then cinnamon-brown, the edges white-fimbriate [white-fringed]

Stem:
4-8cm x 0.4-1cm, more or less equal or widening downward, clavate-subventricose enlarged toward base, stuffed to hollow; the same color as cap or paler; becoming bald, striatulate [finely striate], (Kauffman), entirely pruinose, pink at the top only, elsewhere cream color or ivory, (Stuntz)

Veil:
no ring

Microscopic spores:
spores 8-10 x 5-6 microns, elliptic - almond-shaped, inequilateral, smooth, pale ochraceous under microscope; cystidia moderately abundant, 45-50 x 12-16 microns, "rather stout, ventricose above a short thick pedicel, obtuse at the apex", cystidia colorless, thick-walled

Spore deposit:
[presumably a shade of brown]

Notes:
Inocybe kauffmanii has been found in WA and OR (Kauffman), and CA (Nishida). Collections from BC are at the University of British Columbia.
