BRIEF DESCRIPTION: (t.b.d.)

The spores measure (5.8-) 7.2 - 10.0 (-12.8) x (5.3-) 6.8 - 9.5 (-12.0) µm and are globose to subglobose (infrequently broadly ellipsoid) and amyloid. Clamps are not present at bases of basidia.

The species is known from oak forests from central Mexico to Andean Colombia.

Amanita arocheae is deadly POISONOUS. A common name for the species in Mexico is "hongo gris." It is similar to A. phalloides (Fr. : Fr.) Link.  For other similar taxa, see the latter species.  The reader may want to examine the recently revised key to the taxa of sect. Phalloideae in North America.-- R. E. Tulloss
