intro	This species is somewhat similar to Amanita fulvosquamulosa, but has distinctly narrower spores.
cap	The 50 - 125 mm wide cap of Amanita sp-Arora-01-560 is orangish tan. At first it is nearly globose, and it becomes convex as it matures. The margin of the cap is decorated with with floccose material. The cap bears a dense layer of very thin, pallid remnants of the inner surface of the volva.
gills	The gills are white and have a flocculose-pulverulent lower edge.
stem	The stem is white and bruises pinkish; it has no membranous ring, but is decorated with floccose material. The volva is saccate, thick, up to 50 × 38 mm, and its outer surface becomes colored like the cap's skin, but is paler.
odor/taste	Neither the odor nor the taste of this species has been reported.
spores	The spores of this species measure (7.0-) 9.3 - 13.9 (-14.5) × (3.8-) 4.1 - 4.9 (-5.1) μm and are mostly elongate to cylindric (sometimes bacilliform), and amyloid. Clamps are probably absent from bases of basidia.
discussion	This species is known from the Northern and Copper Belt Provinces of Zambia. The most similar named species appears to be A. fulvosquamulosa—R. E. Tulloss and D. Arora

intro

Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain.

The following material is based on field notes of D. Arora and original research of R. E. Tulloss.

pileus

50 - 125 mm wide, uniformly brownish orange, subglobose at first, then convex; context not recorded; margin appendiculate; universal veil as irregularly fragmented thin layer of buff to grayish-buff to pinkish buff to reddish tan floccose-fibrillose material.

lamellae

??, ??, white, with edge minutely flocculose-pulverulent; lamellulae ??.

stipe

100^± × 12 - 25 mm, white above, below with reddish tones, scaly-floccose, totally elongating; context not recorded; exannulate; universal veil saccate, membranous, "thick-felty," up to 50 &time; 38 mm, pallidly concolorous with pileus on exterior surface.

Spore data for collections
provisionally identified as: Amanita sp-Arora-01-560

Spore data sets and their composite

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
