intro | The following information is based on the original description of the present species and on Gilbert (1940 & 1941). |
cap | The cap of A. subvaginata is up to 32 mm wide, convex, ashy-gray, with a striate margin. The volva forms a powdery covering. |
gills | The gills just reachg the stem and are close, white, and have a finely roughened edge. |
stem | The stem is up to 39 mm long, stout, with a powdery covering, and solid (at first stuffed then hollow, according to Gilbert 1941), with a slightly bulbous base. The volva is present on the edge of the bulb, marginate and ashy-gray. |
odor/taste | The odor and taste for this species have not been described. |
spores | The spores measure 7.5 - 9.0 µm in diameter and are globose and inamyloid. Gilbert (1940) presents seventeen drawings of spores, six are or may be correctly oriented for measurement and yield these dimensions: 8.7 - 9.7 × 7.8 - 8.8 µm. They are subglobose to broadly ellipsoid or, perhaps occasionally, globose. Note that, as is usually the case, the report of Amanita spores as truly and consistently globose is not borne out when the spores are measured only in lateral view. |
discussion |
According to Reid (1980), the present species is known only in the vicinity of Sydney, New South Wales (Australia). Associated vegetation is not reported in the literature available to us. This species has persistently been misclassified as belonging in section Vaginatae, possibly because of the name the authors' chose for it. The persistent, powdery volva which remains attached to the cap at maturity and the volva remaining on the margin of the bulb strongly suggest a comparison to Amanita farinosa Schwein. and similar taxa. After the original publication, various authors seem to convert "marginate" to "limbate or saccate" without providing any reason for the change. The presence of a bulb (a stem that is not totally elongating) is indicative of proper assignment of Amanita subvaginata to section Amanita.—R. E. Tulloss and L. Possiel |

lectotypes | AD?? [Notes: Gilbert had in his possession (during the preparation of his spore drawings for this species) at least parts of four of Cleland's collections including the lectotype, which Gilbert designated (Gilbert 1940). If any of these collections were (in their entirety) in Gilbert's herbarium at the time of his death, they must be presumed lost. Grgurinovic (1997) does not mention A. subvaginata at all in her revision of the material from AD. If no collection can be found, the plate that is used to illustrated this taxon page is original material and would be the lone candidate for lectotype. A search for collections that are original material of the present species would be worthwhile.—ed.] | ||||||||

discussion |
Reid (1980) did not revise any material of this species. Wood (1997) misapplied the name of this species to a species belonging to section Vaginatae. Grgurinovic (1997) did not treat this taxon. During Gilbert's preparation of his major work on the Amanitaceae, he had access to four collections of original material of this species. If he retained any of this material, then such material must be assumed to have been lost with his herbarium. The identifying information on the four collections from which Gilbert's spore drawings were made is as follows:

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.
