name	cinereopannosa sensu M. S. Yuan
name status	sensu
english name	"Yuan's Asian Gray Rags Lepidella"
intro	The following is based in part on the revision of this probably distinct species by Yang (1997).
cap	The fruiting body of A. cinereopannosa sensu M. S. Yuan is medium-sized to large. The cap is 80 - 150 mm wide, convex to applanate, and generally grayish, but brownish at the center. The volval remnants on the cap are felty to floccose, and grayish to gray to dark gray or brownish. The cap's margin is appendiculate and non-striate; its flesh is white.
gills	The gills are free, white, crowded; the short gills are attenuate, plentiful.
stem	The stem is 10-15 × 1.5-2.0 cm, subcylindrical or slightly tapering upward, solid, white, middle part with fibrillose squamules; apical part with farinose squamules; its context is white; the basal bulb is subclavate to ventricose, 2.5-3 cm wide. The volval remnants are as gary to grayish farinose to felty patches near apex of bulb, forming a short limb. The annulus is subapical, white, thin, membranous, easily broken and fugacious.
odor/taste	The odor is indistinct.
spores	The spores of this taxon measure (10.0-) 10.5 - 13.5 (-14.5) × (6.5-) 7.0 - 8.5 (-9.0) µm and are ellipsoid to long ellipsoid and amyloid. Clamps are not present at the bases of basidia.
discussion	Amanita cinereopannosa sensu M. S. Yuan is only known from southwestern China. This mushroom is similar to A. cinereopannosa Bas (1969), originally described from the eastern U.S.A. Amanita cinereopannosa differs from A. cinereopannosa sensu M. S. Yuan in its paler cap, paler volval remnants, and smaller spores.
