Technical description (t.b.d.)

BRIEF DESCRIPTION: The cap of Amanita cinereoannulosa is 60 - 82 mm wide, roughly planar at maturity, sometimes subumbonate, sometimes slightly depressed, polished, nonappendiculate, and with an apparently nonstriate or very short-striate margin. The cap is drab or paler. The volva is absent or present as a gray to pallid, thinly stretched, broad patch over the center of the cap.

The gills are narrowly adnate, moderately close, and white to creamy white. The short gills are truncate to subtruncate to subattenuate, of diverse lengths, plentiful, and unevenly distributed.

The stem is 87 - 137 x 15 - 20 mm, whitish, narrowing slightly upward, with slightly hollow flesh. The saccate volva is of uniform height, membranous, rather thick, sheathing, ample, and pallid.

The spores measure (9.3-) 9.9 - 14.7 (-20.3) x (5.6-) 6.4 - 8.6 (-10.2) µm and are ellipsoid to elongate and inamyloid. Clamps are prominent and plentiful at the bases of basidia.

Amanita cinereoannulosa was originally described from the state of South Australia, and has not been reported from anywhere else since as far as I know.

Cleland reported a bulb at the base of the stem; this cannot be ascertained with certainty from the dried material of the type, which I have examined. A collection of fresh material of this species that can be thoroughly examined, photographed, and annotated is greatly needed. -- R. E. Tulloss
