| intro | The following description is based on Beeli (1935) and Gilbert (1941). |
| cap | The cap of Amanita fulvosquamulosa is 80 mm wide, plano-convex, with thin flesh and a smooth margin. The cap is brown-tawny with a slightly prominent umbo and many pale squamules from the volva. The flesh is white. |
| gills | The gills are free, rounded at the stem end, 8 mm broad, white. The form of the short gills is not known. |
| stem | Its stem is 110 × 11 mm, cylindrical, totally elongating, curved right, stuffed, undecorated, and white or slightly tinted pink. The ring was described as pulverulent and superior, white. The volva is membranous, ample, and white. |
| odor/taste | The odor and taste of this species were not recorded. |
| spores | The spores of this species measure 8.0 - 11.0 × 4.5 - 6.0 μm [as measured from the spore drawings of Gilbert (1940)] and are elongate on average and amyloid. |
| discussion |
The present species was originally described from the Democratic Republic of Congo in dry forests. The totally elongating stipe, narrow spores, colors of the cap and volva, very thick volval sac, pinkish tint to the stem, and the floccose upper stipe all support the placement of the present species in section Amidella. Compare to other species described by Beeli—A. goossensiae and A. fulvopulverulenta—and to A. sp-Arora-01-560.—R. E. Tulloss |

The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. 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 derived from the protolog of the present taxon, (Beeli 1935), and (Gilbert 1940 & 1941). | ||||||||||||||||||||

| discussion |
The pigmentation, flocculent annular zone, totally elongating stipe, thick fleshy saccate volva with an inner later left as scales on the pileus, and amyloid and apparently elongate spores all argue for probable placement of this species in Amanita sect. Amidella. A Zambian collection somewhat similar to A. fulvosquamuloa but having apparently narrower spores is A. sp-Arora-10-560. Sporographs of the two species are compared in the following figure: For further discussion see the technical tab of the page for A. goossensiae. | ||||||||||||||||||||

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.
