| 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 is derived from the protolog of this species. from protolog: Basidiomes small. | ||||||||||||||||||||
| pileus | from protolog: 27 - 42 mm wide, brown (6C4-5) to darker brown (6E6) over disc; context firm, white; margin plicate-striate; universal veil as small patches and pointed warts, gray-brown (6C2), denser over disc, scattered at margin, persistent. | ||||||||||||||||||||

| discussion |
Since Miller compares the present species to A. lignophila, a poorly understood name thought by some to apply to a species similar to the North American A. brunnescens (e.g., Lamoureux 2006). At the time of Miller's writing, such taxa were considered to belong in the Phalloideae. They are presently commonly considered to be near basal to section Validae. Note: Since clamps are usually considered to be absent in sect. Validae a revision of the original material is needed.—ed. | ||||||||||||||||||||

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.
