| intro | No macroscopic dimensions have been reported for the present species. |
| cap | The cap of Amanita annulatovaginata var. atra is nearly black with an umbrinous or fulvous tint in the center in some specimens. The cap is narrowly ovoid at first and then expands to plano-convex; at least sometimes it has a low, broad umbo. The white flesh narrows to a membrane at about one-quarter to one-third of the distance from the center to the edge. The margin is striate for about one-half of the cap's radius. None of the specimens in the watercolor illustration that has been used to define the species has any volval material on its cap. |
| gills | The gills of A. annulatovaginata var. atra are free and whitish. Nothing is known concerning its short gills. |
| stem | The stem is off-white, unchanging, cylindric or narrowing slightly upward, and flocculose for the uppermost one-quarter to one-third of its length. The ringless stem's flesh appears hollow and whitish in the defining watercolor painting. The volva of this mushroom is saccate, whitish, and robust. The sides of the sac are fleshy; and the sac is apparently attached to stipe only at the very base and encloses approximately the bottom third of the stem. |
| odor/taste | Odor and taste for this mushroom have not been reported. |
| spores | Spores from the type of A. annulatovaginata var. atra are (10.1-) 10.3 - 11.0 × 6.6 - 7.6 μm and ellipsoid and inamyloid. Status of clamps on the basidia is unknown. |
| discussion | Because there is no good evidence that the material to which this invalid name has been applied truly belongs in Amanita sect. Caesareae, we have placed it in sect. Vaginatae where it seems to belong. The other varieties of A. annulatovaginata will be found in sect. Caesareae.—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 information below is derived from the protolog, the published watercolor of Goossens 773 (Beeli 1935: pl. II (fig. 5); Gilbert 1941: tab. 11) and from spore drawings in (Gilbert 1940). The only information published by Beeli with regard to this taxon is that the pileus is violet-black. RET can see no violaceous tint in either reproduction of the Goossens watercolor. All information from the above sources is derived from original material; hence, the magenta font is used throughout this tab. | ||||||||
| pileus | from protlog: width unknown, black with umbrinous or fulvous tint over disc in some specimens, narrowly ovoid at first, becoming plano-convex, at least sometimes with low broad umbo; context whitish, narrowing to membrane at about one-quarter to one-third of radius; margin striate (ca. 0.5R); universal veil absent in three specimens shown in watercolor. | ||||||||
| lamellae | from protlog: free, density unknown, whitish; lamellulae unknown. | ||||||||
| stipe | from protlog: dimensions unknown, off-white, unchanging, cylindric or narrowing slightly upward, flocculose for apical one-quarter to one-third of stipe; context hollow, whitish; exannulate; universal veil as saccate volva, whitish, robust, with limbs fleshy, apparently attached to stipe only at very base, enclosing approximately basal third of stipe. | ||||||||

| discussion |
Gilbert believed that the present variety was no different from the type variety of A. annulatovaginata. For a counter argument, see here. It seems possible that the present taxon should be assigned to Amanita sect. Vaginatae on the strength of Goossens' watercolor. It appears that the upper stipe is flocculose from before the expansion of the pileus onward. In addition, the cap color is very much darker than in the type variety of A. annulatovaginata and the size of the spores is smaller in var. atra. We hope the users of this site will excuse us for listing one proposed variety of a species in a different section from the other varieties. | ||||||||

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.
