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 based entirely on (Yang 2001).

| discussion |
Unfortunately, the lectotype of A. pallidocarnea comprises only an imperfect fruitbody—about a quarter of the pileus connecting with the upper part of the stipe; the lower part of the stipe, and the volva on the stipe base are not preserved. A felty to submembranous, dirty white, volval remnant was found on the pileus (fig. 1).
Due to its basidiome with pink lamellae, and a saccate volva on the stipe base, features shared with the genus Volvariella, A. pallidocarnea was suspected of not being a member of the genus Amanita (Yang 1997: 102). Having studied the lectotype, and additional material, I found that it is an Amanita, and is characterized by its dark colored pileus with relative long striations along the pileal margin, its pink lamellae, pinkish stipe, globose to subglobose spores, and volval remnants with fairly abundant to abundant inflated cells.
Amanita vaginata var. roseilamellata Bresinsky, which was originally described from Germany, also has pinkish lamellae (Bresinsky & Einhellinger, 1987), but differs from A. pallidocarnea by its paler pileus, white to greyish stipe, and narrower spores. Furthermore, judging from the description and illustrations provided by Bresinsky & Einhellinger (1987), A. vaginata var. roseilamellata might have shorter striations along the pileal margin and a more strongly constructed volva with fewer inflated cells. |
