intro This text is derived from the original description of Amanita pseudopantherina.

The fruiting bodies of Amanita pseudopantherina are medium-sized to large.
cap The cap of the present species is 35 – 120 mm wide, plano-convex to planar, and brownish, yellow-brown to brown.  The volva is present as pyramidal to subconical, bumpy, dirty white to white remnants.  The cap’s margin is slightly grooved for about 30% of the radius.  There is no material hanging from the margin.  The flesh is white.
gills The gills are free, crowded, and white.  The short gills are truncate and plentiful.
stem The stem is 65 – 160 × 7–15 mm, subcylindric to narrowing upwards; its surface is white, covered with fluffy scales of the same color.  The stem's basal bulb is 10 – 30 mm wide, globose to subglobose.  The volva is present as fluffy, white remnants arranged in belts on the lower part of stem and often forms a short "rolled sock" at the top of the bulb.  The ring hangs from a point 20 – 40 mm below the stem's top and is white to yellowish with a brownish to brown edge.
odor/taste The odor and taste of this species were not recorded.
spores The spores measure 9.5 – 12.0 × 8.0 – 10.0 µm and are mostly broadly ellipsoid, occasionally subglobose or ellipsoid and inamyloid.  Clamps at the bases of basidia are rare or absent.
discussion In China, A. pseudopantherina is similar to A. parvipantherina Zhu L. Yang et al., A. subglobosa Zhu L. Yang and A. subparvipantherina Zhu L. Yang et al.  However, A. parvipantherina has a relatively smaller and more slender fruiting body and relatively narrower spores [Q = (1.13-) 1.22 - 1.54 (-1.62)].  Amanita subglobosa can be distinguished from A. pseudopantherina by its relatively darker colored cap and the common presence of clamps.  Amanita subparvipantherina possesses narrower spores [Q = (1.20–) 1.28–1.5 (–1.69)].  Microscopic review indicates the ratio of inflated cells to hyphae in the volva on the cap is clearly greater in A. subparvipantherina than in the present species.—Yang-Yang Cui and Rachel Warner
