| intro | This description is based on the original description of Amanita foetidissima. |
| cap | According to the original description of A. foetidissima (Reid and Eicker, 1991), the cap is 70 - 140 mm wide (and said to grow much larger), initially conico-convex, then convex or convex-campanulate and finally applanate, pale creamy buff to buff, and occasionally more brightly colored with yellowish ochre tints. The surface disrupts from an early age into thick, soft, concolorous or darker, floccose warts, passing into cob-webby fibrils towards the margin. |
| gills | The gills are 10 - 20 mm broad and pale cream to dirty cream. |
| stem | The stem is 70 - 160 × 10 - 20 mm, solid, sqarrose, with buffy brown squamules on a whitish background. |
| spores |
The spores measure 7.0 - 9.0 × 6.2 - 8.0 µm according to the published description and are amyloid and subglobose to globose to broadly ellipsoid. Basidia bear clamps. Examination of spores from a single specimen from a collection cited in the published description yielded measurements of (8.3-) 9.0 - 10.6 (-11.5) × 7.0 - 8.5 (9.0) µm, and the spores are broadly ellipsoid to ellipsoid. |
| discussion |
Amanita foetidissima was originally described from South Africa. It has also been reported from Zambia. Unfortunately, the name is invalid as published, due to uncertainty as to which of two herbaria named in the paper is the location of the holotype. This is a species of grasslands and public open spaces without trees. It is strikingly similar both macro- and microscopically to A. nauseosa (Wakef.) D. A. Reid and is a probable vicariant ("sister") taxon of the latter. One difference between the two is the occasional appearance of A. foetidissima with rather strikingly bright cap colors. This suggests to me the possibility that it is subject to something akin to the "yellowing syndrome" that is observed in a number of taxa such as Amanita subsolitaria (Murrill) Murrill.—R. E.

| intro |
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 not directly from the protolog is based upon original research by R. E. Tulloss. | ||||||||

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.
