| intro | The yellow cap of this variety was the only originally stated character differentiating it from A. annulatovaginata. See the description of Amanita annulatovaginata. |
| cap | The yellowish cap of A. annulatovaginata var. citrina is plano-convex, with a low umbo about the same width as the flaring top of the stem. The cap flesh is yellow immediately below the cap's skin, but otherwise white or whitish. The margin of the cap bears very long striations extending to the very edge of the umbo. There are no remnants of the volva to be found on the cap. |
| gills | The gills are free or nearly free and whitish. |
| stem | The whitish stem is subcylindric or narrows upward very slightly. The stem's flesh is whitish. The stem is stuffed or hollow. It bears a white, superior ring that is funnel-shaped at first. The saccate volva is whitish, membranous, and encloses the bottom fifth (more or less) of the stem. |
| odor/taste | Nothing is known about the odor and taste of this mushroom. |
| spores | Spores from var. citrina according to drawings of spores in Gilbert (1940) measure 12.2 - 13.0 (14.6) × 8.1 - 8.6 (-10.6) μm and are ellipsoid to elongate and inamyloid. The status of clamps on the bases of basidia is unknown. |
| discussion | Much more information is needed about the cluster of taxa that Beeli named as varieties of A. annulatovaginata.—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 839 (Beeli 1935: pl. II (fig. 3); Gilbert 1941: tab. 12 (fig. 2)) and from spore drawings in (Gilbert 1940). The only information published by Beeli with regard to this taxon is that the pileus is yellowish. All information from the above sources is derived from original material; hence, the magenta font is used throughout this tab. | ||||||||
| pileus | from protolog: ca. 30 mm wide (per figure), yellow to yellowish, plano-convex, with low umbo about same diameter as flaring stipe apex; context yellow immediately below the pileipellis, otherwise white or whitish, narrowing rapidly for about one third of the cap radius, then membranous to margin; margin long-striate (ca. 0.8R), with striations extending to edge of umbo; universal veil absent. | ||||||||
| lamellae | from protolog: free or nearly free, density unknown, whitish, ca. 2.5 - 3 mm broad (per figure); lamellulae unknown. | ||||||||
| stipe | from protolog: ca. 64 × 4 mm, whitish, subcylindric or narrowing upward very slightly, undecorated; context stuffed or hollow, whitish; partial veil white, superior, at first infundibuliform; universal veil saccate, whitish, membranous, ca. 14 - 16 × 6 - 8.5 mm, (per figure), enclosing bottom one-fifth of stipe. | ||||||||

| discussion |
Because of the yellow cap, the very thin pileus with long marginal striations, the persistent partial veil, and the rather large, ellipsoid spores, this species may be recognizable if it is found again. It is very probable that this entity will prove to be distinct at species rank from A. annulatovaginata. | ||||||||

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.
