intro |
The article containing the protolog of this species can be obtained as a PDF (here). 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 not directly from the protolog of the present taxon is so marked. NOTE: Spore measurements from papers by Z. L. Yang use his "Times New Roman" face for "Q" and "Q'"—respectively, " from protolog: Basidiomes medium-sized to large. | ||||||||

discussion |
In the protolog, the author compares the present taxon with other taxa of Bas' stirps Cinereoconia. In the following figure sporographs for the taxa cited by Yang are compared. Spores alone distinguish the present species from A. griseofarinosa and A. cinereoconia from protolog: "Amanita griseoverrucosa may be keyed out in Amanita [subsection Solitarae Bas] stirps Cinereoconia of section Lepidella in the system of Bas (1969). In that stirps, A. griseoverrucosa is similar to A. griseofarinosa Hongo, A.vestita Corner & Bas, and A. cinereoconia G. F. Atk. Amanita griseofarinosa, originally described from Japan, has a smaller fruitbody with darker colored, farinose to tomentose volval remnants on the pileus, and proportionally wider basidiospores. Furthermore, the volval remnants on the pileus of A. griseofarinosa consist of irregularly arranged elements with more inflated cells and fewer filamentous hyphae (Yang 1997, Yang and Doi 1999, Yang’s unpublished data). Amanita vestita, originally described from Singapore, has a much smaller fruitbody with umber, buff to brownish floccose-felted volval remnants consisting of irregularly arranged elements, and slightly smaller basidiospores (Corner and Bas 1962, Bas 1969, Yang, Li and Wu 2001). Amanita cinereoconia, originally described from the U.S.A., has a rather slender fruitbody with a pileus covered with pulverulent to small warted volval remnants, and longer and narrower basidiospores with higher Q. In addition, A. cinereoconia has a peculiar small like “old ham” or “chloride of lime” (Bas 1969, Jenkins 1986). "Amanita griseoverrucosa looks like A. japonica Bas, A. miculifera Bas & Hatan., and A. onusta (Howe) Sacc. However, the latter three species have rather common clamps and were placed in different stirpes by Bas (1969) and Bas and Hatanaka (1984). Furthermore, A. japonica and A. miculifera, both originally described from Japan, usually have much more strongly rooting bulb and darker colored volval remnants on the pileus. Amanita miculifera additionally has somewhat larger basidiospores (Bas and Hatanaka 1984). Amanita onusta, described from the U.S.A., has a smaller fruitbody with an often deeply rooting and sometimes sinuous or contorted bulb and a pileus with deeper-colored (dark gray to brownish-gray or gray-brown) pyramidal to conical volval remnants (Bas 1969, Jenkins 1986, Tulloss et al. 1995)." | ||||||||

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.
