intro | This text is derived from the original description of Amanita pseudoprinceps. The fruiting bodies of Amanita pseudoprinceps are medium-sized to large. |
cap | The cap is 70 – 120 mm wide, plano-convex to planar, usually yellow-brown to brown over the entire cap, occasionally dark brown to brown in the center, gradually changing towards the margin to cream to white. The cap’s margin is radially grooved for 20% to 30% of the cap's radius. There is no material hanging from the cap's edge. The flesh is white. |
gills | The gills are free, crowded, and white to cream. The short gills are truncate and plentiful. |
stem | The stem is 100 – 150 × 10 – 15 mm, nearly cylindric or narrowing upwards; its surface is white to dirty white, covered with dirty white to brownish fibrils; the stem lacks a basal bulb. At the stem's base, the volva is saccate, 40 – 60 × 30 – 40 mm, membranous, outer surface is white to dirty white, inner surface is brownish. The ring is white to cream. |
odor/taste | The odor and taste were not recorded for the present species. |
spores | The spores measure 10.0 – 12.0 × 8.5 – 10.5 µm and are subglobose to broadly ellipsoid and inamyloid. Clamps are common at bases of basidia. |
discussion | Amanita pseudoprinceps is currently known to occur only in China, Nepal and Thailand. Amanita pseudoprinceps can be confused with A. princeps Corner & Bas. However, the latter differs from the former in its relatively larger fruiting body with a cap ca. 10 – 20 cm in diam., and a white saccate volva with its outer surface cracking and peeling into thin, brownish patches.—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. | ||||||||||||||||||||||||
basidiospores | protolog: [120/6/4] (9.5-) 10.0 – 12.0 (–14.0) × (8.0–)8.5 – 10.5 (–12.0) μm, (Q = 1.02 – 1.23 (–1.27); Q' = 1.12 ± 0.04), colorless, smooth, thin-walled, inamyloid, subglobose to broadly ellipsoid; apiculus small; contents not described; color in deposit not described. | ||||||||||||||||||||||||
