intro | This text is derived from the original description of Amanita neocinctipes. The fruiting bodies of Amanita neocinctipes are medium-sized. |
cap | The cap is 40 – 70 mm wide, planar, and gray-brown to dark gray over the entire cap, or often dark gray in the center, gradually changing towards the margin to brown-gray, gray to grayish. The volva is present as pyramidal, fluffy to patchy, dark gray to gray remnants. The cap’s margin is radially grooved covering 30% - 40% of the cap's radius. There is no material hanging from the edge and the flesh is white. |
gills | The gills are free, crowded, and white. The short gills are truncate and plentiful. |
stem | The stem is 80 – 110 × 3 – 10 mm, nearly cylindrical and narrowing upwards. The upper part of stem is dirty white to grayish and covered with powdery squamules all of the same color. The lower part of stem is grayish to gray and decorated with fibrous squamules. The stem lacks a basal bulb. At the stem's base, the volva is present in fluffy to felted, gray to dark gray remnants, arranged irregularly or in incomplete belts or rings. |
odor/taste | The odor and taste were not recorded for the present species. |
spores | The spores measure 8.0 – 10.5 × 7.0 – 9.0 µm and are subglobose to broadly ellipsoid and inamyloid. There are no clamps at the bases of basidia. |
discussion |
Amanita neocinctipes corresponds to Amanita sp. 10
in Yang
(2015).
Amanita neocinctipes is described from
Guangdong Province, China.
It is distributed in a subtropical forests
dominated by Beech (Fagaceae). To date, four species of A. sect. Vaginatae with a nonsaccate volva were described from China, including A. cinctipes Zhu L. Yang et al., A. griseofolia Zhu L. Yang, A. liquii Zhu L. Yang et al. and A. neocinctipes. The former three species can be separated from A. neocinctipes by molecular phylogenetic, morphological and ecological evidence. Amanita cinctipes differs from A. neocinctipes in its globose to subglobose spores (Q = 1.0 - 1.15; Q = 1.10). Amanita griseofolia can be distinguished from A. neocinctipes by its globose to subglobose spores (Q = 1.0 - 1.10 (-1.18)), and its distribution in mixed forests. Amanita liquii is different from A. neocinctipes by its relatively larger and darker fruiting body, larger spores (Q = 1.0 - 1.09 (-1.20) and its subalpine distribution.—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. | ||||||||||||
