intro | For the present, data will be collected on the technical tab of this taxon page. |
discussion |
At first, from above, this mushroom seems to be
rather like
Amanita
texasorora—because of the fragmenting,
graying volval patches left on the cap. However,
the present species has a weakly structured, white
ring on the stem.
This structure can, at least sometimes, break up so that
its lower part falls away and slides down the stem
until it catches on the stem's surface. In the past this species was called A. sp-MO07 on this site.—R. E. Tulloss |

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 based on collectors' notes and photographs, molecular research of Dr. L. V. Kudzma and other original research of R. E. Tulloss. | ||||||||||||

discussion | At first, from above, this species seems to be a specimen something akin to Amanita rhacopus. However, the present species has a weakly structured, white partial veil. This structure can, at least sometimes, break up so that its lower part can fall away and slide down the stipe until it catches on the stipe surface. | ||||||||||||

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.
