| intro | For the moment, what is know of this species may be found on the technical tab of this page. |
| odor/taste | Neither the odor nor the taste of this taxon has been described. |
| discussion | Unfortunately, the species described by Wood has little in common with the type of A. grisea, which was studied by RET. The present taxon is known from three sites within New South Wales. Its habitat is described as "heath," "tall forest," or "sclerophyll woodland." At least, the latter would contain Eucalyptus—R. E.

| 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 on Wood (1997). | ||||||||||||||||||||
| pileus | pallid cream-gray to pallid gray-brown (12A1-2, 10YR/6-8/2-4) with darker color over disc, up to 50 mm wide, "slightly radially fibrillose"; context not described; margin "not pellucid striate"; universal veil as "scattered fine fragile flat scales" or "granular" material, "off-white to pale grayish," "crowded toward center." | ||||||||||||||||||||
| lamellae | free, fairly crowded, "thin," "white to pale cream," with edge "mostly white"; lamellulae "in one or two" ranks. | ||||||||||||||||||||
| stipe |
60 × 10- mm, "white, discoloring with
age, "smooth or vaguely irregularly hairy below";
base rounded bulbous;
partial veil "white, narrow," "membranous,
fairly fragile, often
not persisting"; universal veil as "ring of
scales at top" [of bulb], "but partly or wholly
showing clear membranous rim at top with small, but
distinct free margin." [Editor's note: The description of the universal veil is internally contradictory. The habit drawing simply shows two wavy lines around the top of the bulb with the upper one broken in a few places. This description does not match the type study done by Tulloss (see the tech tab of Amanita grisea). | ||||||||||||||||||||

| discussion |
The species described by Wood as belonging in section
Validae might belong there if the free volval
limb is described in error (e.g., if taken up as
an interpretation of the protolog). We consider
the placement of A. grisea sensu A. E. Wood
unsettled. Amanita grisea seems assignable to sect. Amidella according to a type study reported on this site. Its spores are reported to be [40/1/1] (8.5-) 9.0 - 12.5 (-14.2) × (7.0-) 7.3 - 9.9 (-10.9) μm, (L = 10.8 μm; W = 8.4 μm; Q = (.105-) 1.06 - 1.49 (-1.53); Q = 1.29). It is clear that Wood misapplied the name "A. grisea." | ||||||||||||||||||||
