intro | The following is based on the original description by Wood (1997). |
cap |
The cap of A. sordidobubalina is up to 70 mm wide, mostly golden brown to yellowish buff, sometimes with gray shades [Note: Wood references his colors to three plates in the 1950 color book by Merz and Paul. To our eyes, the cited colors range from shades of orangish-tan to a sordid tan that has a slightly greenish component. The darkest color reported by Wood is approximately midway between an olive tone and a saturated orange-brown (Merz and Paul, plate 15 C6).], darker in the center, becoming paler with age, convex then plane, finally slightly upturned, smooth, dry, with a striate margin (1/3 of the radius according to the text; 1/5 of the radius according to the illustration). Volval remains are absent. |
gills |
The gills are free, narrow, crowded, white to very pale cream, with a slightly minutely roughened and concolorous edge. The short gills are present in at least two series. |
stem |
The stem is up to 180 × 10 mm, equal to slightly bulbous below, white, smooth or sometimes with sparse white fibrils. No ring is present. The saccate volva is prominent, persistent, membranous, large, and white. Wood says that the volva "has a large free margin." Since the illustration shows the volva proportionately small compared to the stem length, we choose to interpret Wood's words to mean that volval sac is minimally attached to the stem base—attached for only a short distance. |

spores |
The spores measure 10.0 - 12.6 (-13.5) × (9.6-) 10.0 - 12.6 µm and are globose to subglobose and inamyloid. Clamps are absent from bases of basidia. |
discussion |
Wood describes the mushroom as occurring in tall open forests and sclerophyll forests from the state of New South Wales, Australia. A sclerophyll forest in the Australian bush is a forest of hard-leaved plants including Eucalyptus in the overstory (wikipedia). Wood compares A. sordidobubalina to A. vaginata sensu A. E. Wood. Given the limited state of knowledge about these taxa, this strikes us as a reasonable choice. This is the last Wood species in section Vaginatae that we transcribed for the Amanitaceae Studies site. It is very clear to us that the Australian taxa reported by Wood contain a treasure trove of morphological and phylogenetic information that has yet to be uncovered. We expect a revision of Wood's taxa to be highly profitable taxonomic work.—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. | ||||||||

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.
