intro | This text is derived from the original description of Amanita shennongjiana. The fruiting bodies of Amanita shennongjiana are small to medium-sized. |
cap | The cap is 40 – 90 mm wide, plano-convex to planar, raised over the stem (umbonate), grayish brown to brownish. Volva is mostly absent, but occasionally present as white patches. The cap’s margin is radially grooved covering 40% - 50% of the cap's radius. There is no material hanging from the edge. The flesh is white. |
gills | The gills are free, crowded, and white. The short gills are truncate and plentiful. |
stem | The stem is 100 – 160 × 5 – 12 mm, nearly cylindrical or narrowing upwards, white to dirty white,and covered with minute, concolorous fibrils. The stem lacks a basal bulb. At the stem's base, the volva is saccate, 15 – 30 × 10 – 15 mm, membranous, and is easily broken into large patches during development of fruiting bodies; both the inner and outer surfaces are white. |
odor/taste | The odor and taste were not recorded for the present species. |
spores | The spores measure 10.0 – 12.0 × 9.0 – 11.0 µm and are globose to subglobose and inamyloid. There are no clamps at the bases of basidia. |
discussion |
Amanita shennongjiana is described from central
China (Hubei Province). It has associations with
broad-leaved trees. The European A. vaginata can be confused to A. shennongjiana in appearance, but A. vaginata has a robust fruiting body, a non-umbonate cap with relatively shorter striations on the margin and a relatively thicker volva on the stem’s base.&mdas;Yang-Yang Cui and Rachel Warner |

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 directly from the protolog of the present taxon and associated documen- tation such as sequences deposited in GenBank. | ||||||||||||||||
