intro | The following text is derived from the original description of Amanita veldiei. |
cap | The cap of A. veldiei is 40 - 60 mm wide, shallowly convex to planar, white, shiny, with an appendiculate margin and with a sterile extension beyond the end of the gills. Thick, whitish warts are present, thicker and more conspicuous towards the center passing into cob-webby fibrils towards the margin. |
gills |
The gills are dirty cream and very narrow at both ends. |
stem | The stem is 125 - 130 × 6 - 11 mm (width measured at top of stem), narrowing slightly upward, white, smooth above a well-formed ring, below the ring the stem is covered with white floccose-fibrillose warts, most prominent towards the base. The top of the bulb is covered with white, fibrillose volval remnants. The bulb is up to 22 mm wide, spindle-shaped, and somewhat rooting. The ring is on the upper part of the stem and is membranous, skirt-like, and persistent. |
spores |
The spores measure 12 - 15 × 7 - 8 µm and are amyloid and elongate. Clamps are absent at bases of basidia. |
discussion |
Amanita veldiei was originally described from South Africa. 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. We have not been able to discover if the omission has been corrected. The original authors assigned this species to Bas' stirps Hesleri. They express some concern over the fact that the warts of Amanita hesleri Bas are very dark colored, however, differences in volva color are not uncommon in closely related species in section Lepidella.—R. E. Tulloss and L. Possiel |

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 data are derived from the protolog of the present species. | ||||||||||||||||

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.
