| 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 is derived from (Hongo 1967) and (Yang 1997).
NOTE: Spore data from papers by Z. L. Yang are presented following his use of the "Times New Roman" face for "Q" and "Q'"—respectively, "Q" and "Q." |

| discussion |
The precise placement of this species within section Amanita is not clear to the editors at this time. The "more or less" gelatinized pileipellis seems to suggest separation from the taxa of the provisional series Farinosae. The absence of a limbate limbus internus segregates the present species from the monotypic, provisional series Crenulatae. Nevertheless, the taxon is assignable to the provisional subsection Amanitella; hence, for the moment we assign it to a provisional, monotypic series: Amanita series Rufoferrugineae.
The Japanese name for this species is "kabairo-kona-tengutake" (Doi 1991). |
