english name | "Yunnan Zoned Cap Ringless Amanita" |
intro | This text is derived from the original description of Amanita zonata. The fruiting bodies of Amanita zonata are medium-sized. |
cap | The cap is 50 – 80 mm wide, planar, gray-brown, brown to dark gray in the center, gradually changing towards the margin to gray to gray-brown, and often has an indistinctly dark-colored ring-like zone at the proximal end of the marginal striations. The cap’s margin is radially grooved covering 15% - 30% of the cap's radius. There is not 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 90 – 130 × 4 – 15 mm, nearly cylindrical or narrowing upwards, dirty white, brownish to gray-brown, and is covered with grayish to brownish squamules. The stem lacks a basal bulb. At the stem's base, the volva is saccate, 20 – 35 × 15 – 20 mm, membranous, and the outer surface is white and sometimes with brown tinge while the inner surface is white to dirty white. |
odor/taste | The odor and taste were not recorded for the present species. |
spores | The spores measure 9.0 – 10.5 × 8.5 – 10.0 µm and are globose to subglobose and inamyloid. There are no clamps at the bases of basidia. |
discussion |
Amanita zonata is described from Yunnan
Province, China. This species occurs
in subtropical forests dominated by Fagaceae. Amanita ovalispora, a species described from Indonesia, is similar to A. zonata in appearance and habitats, but the former can be distinguished from the latter by the grayer to darker gray cap lacking an obvious dark-colored ring-like zone at the proximal end of the marginal striations, and broadly ellipsoid to ellipsoid spores (Q = (1.08-) 1.11 - 1.37).—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. | ||||||||||||||||||||||||||||
