| name | Amanita flavella |
| name status | nomen acceptum |
| author | E.-J. Gilbert & Cleland |
| english name | "Australian Yellow Dust Amanita" |
| intro | The following description is based on Reid (1980). |
| cap | The cap of Amanita flavella is yellowish-orange, convex, with a nonstriate margin. The margin is slightly flaring. |
| gills | The gills are crowded, white, and narrowly attached. |
| stem | The stem is 75 mm high, slightly bulbous, attenuate, pale yellow above the ring, and white below. The ring is yellowish, membranous, ample, very narrow, and skirt-like. On the bulbous base of the stem, yellowish powdery warts of volva form one or more rings. |
| odor/taste | This species is reported to have a slight, musty smell. |
| spores | The spores measure 8.5 - 10 × 6 - 6.5 µm according to the original description [E.-J. Gilbert & Cleland (1941)] and are ellipsoid and amyloid. Reid (1980) found the measurements to be 8.0 - 8.5 × 5.0 - 6.5 µm. |
| discussion |
The species was originally described from New South Wales, Australia. No ecological information was provided. Gilbert & Cleland thought this species was similar to Amanita flavoconia G.F. Atk. Amanita flavella also appears to be similar to Amanita flavipes S. Imai.—R. E. Tulloss |

≡Amplariella flavella E.-J. Gilbert & Cleland nom. nud. 1940. Iconogr. Mycol. (Milan) 27, suppl.: 79, 174, tab. 47 (fig. 6). [Lacking Latin diagnosis, specification of holotype, etc. ICBN §36.1, §37.1, etc.] [Gilbert gives the authority for Amplariella flavella as "(E.-J. Gilbert & Cleland) nob." However, the name was not published until the following year (1941). Hence, it was impossible to recombine the name even if it had been validly published in 1940. I have corrected the author citation here.] The editors of this site owe a great debt to Dr. Cornelis Bas whose famous cigar box files of Amanita nomenclatural information gathered over three or more decades were made available to RET for computerization and make up the lion's share of the nomenclatural information presented on this site. | ||||||||||||||||||||

| 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 derived from the protolog and from Reid (1980). | ||||||||||||||||||||

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.
