Amanita manginiana sensu W. F. Chiu |
intro |
The following description is based on Gilbert (1941). |
cap |
Gilbert (1941): Fruiting bodies of Amanita manginiana sensu W. F. Chiu are medium-sized to large, sometimes very large. The cap is 50 - 150 (-200) mm wide, convex to applanate, grey to dark grey to brownish, darker in the center, innately fibrillose, and usually glabrous, although occasionally covered with a few white, membranous volval remnants. The cap's margin is smooth and non-appendiculate, but often with some pieces of annulus remnants hanging. The cap context is white. [Ed. note: the two images, above show the same mushroom in different lights.] |
gills |
Gilbert (1941): The gills are free to subfree and white; the short gills are attenuate. |
stem |
Gilbert (1941): The stem is 80 - 150 × 5 - 30 mm, subcylindric to attenuate upwards, with a surface that is white and covered with white fibrillose to farinose squamules; the stipe's context is white; the stem's basal bulb is 20 - 35 mm wide, ventricose to clavate, or (occasionally) subglobose. At the stipe's base, the volva is limbate, with a free, white to dirty white limb. The annulus is apical to subapical, white, and easily broken during expansion of cap. |
spores |
Gilbert (1941): The spores measure (5.5-) 6.0 - 8.0 (-9.0) × (4.5-) 5.0 - 7.0 (-7.5) µm and are subglobose to broadly ellipsoid and amyloid. Clamps are not present at the bases of basidia. |
discussion |
Gilbert (1941): Amanita manginiana was originally described by Hariot & Patouillard from Viet Nam in 1914. The Chinese mushroom is similar to Amanita manginiana, but there are some discrepancies. Chiu first reported the present species from China in 1948. Amanita manginiana sensu W. F. Chiu is a favored edible mushroom in southwestern China and is often sold in the free markets. It has been reported from Japan recently. See also, A. pseudoporphyria Hongo.—Zhu L. Yang |

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.
