name Amanita grisella
name status nomen acceptum
author E.-J. Gilbert & Cleland
english name "Australian Mystery Amanita"
intro The following description based on that of Reid (1980).
cap The cap of Amanita grisella is mottled light olive with light streaks.  The volva is an incomplete, thin, felty-pulverulent layer; its color is unknown.
gills The gills were not described.
stem The stem is 75 × 6 mm in the upper part.  No other characters were recorded for the type collection.
odor/taste The order and taste were not recorded.
spores The spores from a spore print deposited with the type collection measure 6.9 - 9.5 × 6 - 8 µm according to Reid and are subglobose to broadly ellipsoid and amyloid.  A second spore print in the same packet produced spores of different size-shape according to Reid: 6.5 - 8.75 (-9.0) × 6.0 - 9.0 μm and "mostly ovate or ellipsoid."  Clamps are absent at base of basidia.  Reid found a second spore print from which he reports nearly globose spores and at least one spore with length shorter than width (possibly a misinterpretation).  Gilbert (1940) supplies five drawings of which three are close to being in lateral view and measure 8.5 - 9.8 × 7.0 - 8.5 µm and are subglobose to broadly ellipsoid.
discussion Originally collected in New South Wales, Australia.

As Reid (1980) suggests, we accept only the information known for the field notes deposited with the type and microscopic anatomy of the type.  The habit illustration of Gilbert (1941) conflicts with the field notes and may depict a different fungus.  Likewise, much of the original description must be set aside.

Wood (1997) apparently misapplies the present name.  Wood's species differs from the present one in at least cap color, spore size, and spore shape.
