    • intro Note: Dimensions, except for spore measurements) are taken from Jenkins (1986).
    cap Amanita multisquamosa has a 30 - 110 mm wide, rather pallid cap with a disc tinted tan or brown; the cap margin is distinctly striate.  Most of the specimens found by RET fall at the lower end of the range of cap width.
    gills Jenkins (1986) says the gills are free to remote, crowded, and white; and the short gills are plentiful and truncate.
    stem The stipe is 35 - 130 × 3 - 12 mm (not including notable basal bulb in range of width), white, and annulate. The annulus in this species is often pulled up by the expansion of the pileus and, hence, looks funnel-shaped.  The annulus of A. velatipes G. F. Atk. is often pulled into a similar shape.  The rather pronounced collar of volval remains encircling the top of the bulb is shared with a number of taxa in what might be called the "pantherinoid group": A. albocreata G. F. Atk., A. pantherina (DC. : Fr.) Krombh., A. velatipes G. F. Atk., etc. Note that, on occasion, the volva of species in the "muscarioid group" may be similarly disposed (e.g., see images of A. muscaria var. guessowii Veselý).
    spores The spores measure (6.6-) 7.0 - 11.2 (-15.0) × (5.2-) 5.6 - 8.4 (-8.7) µm and are subglobose to broadly ellipsoid to ellipsoid and inamyloid.  Clamps are rarely present at bases of basidia, according to Jenkins (1986).
    discussion Amanita multisquamosa occurs in mixed coniferous and deciduous forest in eastern North America.

    Jenkins (1986) states that it may have been found in the Pacific Northwest; however, in the last thirty-plus years, I have never seen evidence of this.

    The mushroom should be presumed to be toxic.
