intro This text is derived from the original description of Amanita squarrosipes.  The fruiting bodies of Amanita squarrosipes are medium-sized.
cap The cap is 65 mm wide, convex to planar, grayish to brownish gray.  The cap’s margin is radially grooved for about 20% to 30% of the radius and lacks material hanging from its edge.  The flesh is white.
gills The gills are free, crowded, and white to cream.  The short gills are truncate and plentiful.
stem The stem is 190 × 13 mm, nearly cylindric or narrows upwards, white to grayish, and covered with gray to dark gray squamules under the ring.  The stem lacks a basal bulb. The volva is saccate, 50 × 25 mm, membranous, and has white to dirty white inner and outer surfaces.  The ring hangs from a region 30 mm below the stem's top, the upper surface is grayish and the lower surface is gray brownish.
odor/taste The odor and taste were not recorded for the present species.
spores The spores measure 9.0 – 11.0 × 8.5 – 10.5 µm and are globose to subglobose and inamyloid.  Clamps are common at bases of basidia.
discussion Amanita squarrosipes occurs in subalpine forests with Spruce (Picea), Oak (Quercus) and Rhododendron.  Amanita squarrosipes corresponds to Amanita cf. imazekii in Yang (2015). Morphologically, A. squarrosipes can be confused with A. imazekii Oda et al.  However, A. imazekii has a relatively larger fruiting body, and a white stem densely covered with white to grayish squamules.— Yang-Yang Cui and Rachel Warner
