cap |
Basidiocarps medium-sized to large. Pileus 70 - 150 (-200) mm wide, convex to applanate, sometimes concave, white, covered with white, conical to pyramid volval remnants 1 - 3 mm high and wide; the cap margin is smooth and appendiculate; and the context is white and unchanging. |
gills |
The gills are free to subfree and white to cream; the short gills are attenuate. |
stem |
The stipe is 100 - 200 × 15 - 30 mm, subcylindric or aslightly attenuate upwards, white, covered with white floccose squamules; the context is white; the stipe's basal bulb is 30 - 40 mm wide, ventricose, ovoid to subglobose, with its upper part covered with white, verrucose to granular volval remnants. The annulus is white; its upper surface bears fine, radial striations; and its lower surface, verrucose to conical warts. The annulus is often broken during expansion of the cap. |
spores |
The spores measure (7.0-) 8.0 - 10.0 (-11.5) × (5.5-) 6.0 - 7.5 (-8.5) µm and are broadly ellipsoid to ellipsoid and amyloid. Clamps are common at bases of basidia. |
discussion |
The species was originally described from Japan. Amanita virgineoides is also known from China and South Korea. ZLY's photograph depicts a gathering of this species for sale in a market Bas (1969) defined his stirps Virgineoides based on the present species. This stirps also includes A. miculifera Bas & Hatan. and A. gracilior Bas ex Bas & Honrubia.—Zhu L. Yang and R. E. Tulloss |

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 of the present taxon and the revision of the species by Yang (1997) NOTE: Spore measurements from papers by Z. L. Yang use his "Times New Roman" face for "Q" and "Q'"—respectively, " | ||||||||||||

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.
