    • intro The following is based in part on the original description of A. canescens, but also on research of RET.
    cap The cap of Amanita canescens is 100 - 172 mm wide, pale grayish brown to grayish brown in disc, grayish-brown to pale sordid tan to white beyond disc, white or whitish at margin, plano-convex, sometimes with umbo, may become slightly depressed at full expansion, subviscid to tacky when moist, shiny or dull over disk, shiny near margin.  The cap context is white, 13 - 17± mm thick at stipe, thinning evenly to margin.  The cap margin is nonstriate, appendiculate, decurved throughout expansion; a universal veil is present as plentiful warts, subpyramidal to pyramidal with eroded/striate sides, becoming flocculence near margin, white to cream to tannish cream, darkening somewhat with age, friable, detersile, randomly distributed.
    gills The gills are adnexed to free, then seceding, with short decurrent line on stipe apex, close to crowded, pale orangish cream to cream in mass, cream or sordid cream or watersoaked white with pale orange tint in side view, not changing when bruised or cut, proportionately narrow to moderately broad (10 - 12.5 mm broad), thin and rather fragile, with minutely fimbriate edge; short gills are subtruncate to rounded truncate to subattenuate to attenuate, plentiful, of diverse lengths, rather evenly distributed, with moderate length short gills alternating with gills, with very small short gills between every pair of gills and moderate length short gills.
    stem The stipe is 90 - 140- × 24 - 25 mm, white or near white, narrowing upward (at least slightly), flaring at apex, with abundant white fibrils above partial veil, with white to cream fibrils becoming pale pinkish orange or pale salmon or pale orangish white or pale yellowish orange below (especially in response to handling); bulb 39 - 45 × 39 - 46 mm, subnapiform to ovoid, often split longitudinally here and there; context white, solid, with concolorous larva tunnels; partial veil superior, white to off-white, large, thick, submembranous, very delicate, usually falling to lower stipe or ground after full expansion of pileus; universal veil as occasional irregular patches, randomly distributed on upper bulb or not apparent.
    odor/taste The odor is not distinctive or is faintly fungoid or faintly of cedar wood or burnt sugar, but not unpleasant.  Taste of the species is not recorded.
    spores The spores measure (6.5-) 7.5 - 10.8 (-12.0) × (4.5-) 4.8 - 6.2 (-6.8) µm and are ellipsoid to elongate (occasionally cylindric) and amyloid.  Clamps are absent from bases of basidia.
    discussion The species occurs in both deciduous and mixed woods usually with oak (Quercus) or oak and pine (Pinus) present and has a range extending at least from Connecticut to Alabama, U.S.A.—R. E. Tulloss
