intro |
The original description of this species is found in Yang (1997). |
cap |
The cap of Amanita incarnatifolia is 35 - 70 mm wide, convex to planar, gray to grayish-brownish in the center, and paler towards the margin. The margin is striate, with striations usually consuming 20 - 30% of the cap radius. |
gills |
The gills are free to subfree, pinkish, close, and 5 - 15 mm broad. |
stem |
The stem is 50 - 100 × 5 - 15 mm, white, finely fibrillose. The ring is about 10 - 20 mm below the apex of the stem, is membranous and small, and has both surfaces white. The volva is saccate, 15 - 40 × 10 - 25 mm and white to dirty white on both surfaces. |
spores |
The spores measure (9.5-) 10.0 - 13.0 (-13.5) × (6.5-) 7.0 - 9.0 (-9.2) µm and are inamyloid and ellipsoid. Clamps are present at bases of basidia. |
discussion |
This species was originally described from the provinces of Sichuan and Yunnan, China, where it is known from Pine forests. The species is also known from Japan. —Zhu L. Yang Note: The species can be assigned to stirps Hemibapha, see A. hemibapha (Berk. & Broome) Sacc. |

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 material presented below is derived entirely from the protolog of the present species and from (Yang 2000). NOTE: Spore data from papers by Z. L. Yang are presented following his use of the "Times New Roman" face for "Q" and "Q'"—respectively, " | ||||||||||||

discussion |
A similar species, also with pinkish lamellae has been found once in eastern North America—A. sp-53. A sporograph comparison of the two taxa is presented in the following figure. The taxon now known as A. incarnatifolia was originally described from Japan. | ||||||||||||

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.
