  • cap

    The cap of Amanita griseoverrucosa is 70 - 150 mm wide, convex to planar with a smooth, appendiculate margin.  The cap is dirty white to grayish and sometimes gray to brownish gray. The flesh is white and unchanging.  The volva is dirty white to gray to brownish gray, in warty or conical remnants.

    gills

    The gills are free, white to very pale cream, and up to 15 mm high.  The short gills are attenuate.

    stem

    The stem is 60 - 150 × 7 - 30 mm, subcylindric, white to whitish or grayish, with its lower part covered with gray to grayish, fibrillose squamules; its upper part is covered with white powdery squamules.  The volva is gray to grayish, in warts or as irregularly formed remnants.

    spores

    The spores measure 8.0 - 11.0 × 5.5 - 7.0 µm, and are ellipsoid and amyloid.  Clamps are not present at bases of the basidia.

    discussion

    The species occurs in broad-leaved forests, coniferous, and mixed forests with oak, and pine.  The picture to the left (above) was taken at an elevation of 2,000 m under pine.  The one on the right (above) was taken at 3,000 m elevation under oak.  I believe the two images depict the same species.  The color of the cap of the holotype was intermediate between the two depicted extremes.

    The range of A. griseoverrucosa extends from eastern to western in tropical and subtropical regions of China.—Zhu L. Yang
