| author | A. E. Wood |
| english name | "Australian Death Cap" |
| intro | The following is largely based on the original description (Wood 1997). |
| cap | The single, fairly young collection examined had caps of up to 45 mm wide, convex, smooth, dry, pallid gray, with a greenish metallic sheen when first collected, with a nonstriate margin. Volval remains are present as a few drab cream colored, small, flat, membranous scales. |
| gills | The gills are free, thin, crowded, white to slightly off-white, with a concolorous edge. The short gills are present in at least two series. |
| stem | The stem is up to 50 × 10 mm, smooth, and off-white. The incomplete ring is white, membranous, and "probably would be fugacious." The bulb is pronounced, subglobose, is white, and bears a distinct, white, membranous, free limb that surrounds the stem base. |
| spores | The spores measure 6.2 - 8.9 × 5.5 - 8.3 µm and are globose to subglobose and weakly, but distinctly, amyloid. Clamps are absent from bases of basidia. |
| discussion |
Wood describes the mushroom as occurring in association with Allocasuarina distyla and Casuarina glauca. This species is known from a single collection. There seems little doubt that Wood has placed this species correctly in Amanita sect. Phalloideae. Since the species is known only from one collection and considering the way in which the description is written (from a single, young specimen), the question of the permanence of its ring remains open and collection of additional material is needed. The fact that the cap is described as "finely radially fibrillose" could be interpreted as saying the pigment is distributed similarly to the pigment in such taxa as A. phalloides (Fr. : Fr.) Link, A. arocheae Tulloss, Ovrebo & Halling, A. marmorata Cleland & E.-J. Gilbert, etc. In recent molecular work, which we hope to see in print soon, an Australian species A. marmorata is shown as the most basal in the Phalloideae of the taxa treated, with the exception of the taxa known not to contain amatoxins. It will be very interesting to know whether such species as A. austrophalloides and the Andean-Argentine species A. austroolivacea Raithelh. (with the phalloides-like distribution of pigment) contain amatoxins.—R. E. Tulloss and L. Possiel |

| 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 entirely on the protolog of this species, which does not meet contemporary standards for Amanita taxonomy. | ||||||||

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.
