intro | The following is based on the original research of Zhu L. Yang. |
cap | The fruiting bodies of A. pseudogemmata are small to medium-sized. The cap is 40-90 mm wide, convex to applanate, yellowish to pale yellow-brown, paler towards the margin; its margin is short-striate; it is covered with brownish grey to olivaceous brown verrucouse to farinose volval remnants. Its trama is white. |
gills | The gills of this species are free, crowded, cream-colored; and the short gills are truncate, and of diverse lengths. |
stem | The stem is 60 - 100 × 5 – 15 mm, subcylindrical to attenuate upwards; its surface is cream-colored to white, and covered with yellow to brownish yellow squamules; the stem''s basal bulb is 15 - 40 mm wide, limbate to subtruncate. The annulus is persistent, its upper surface is white and its lower surface, yellowish. |
spores | Spores of A. pseudogemmata measure (6.0-) 7.0-9.5 (-10.5) × (5.5) 6.0-8.5 (-9.5) µm and are broadly ellipsoid to ellipsoid, and inamyloid. Clamps are not present at the bases of basidiae. |
discussion |
Amanita pseudogemmata was originally described from Japan. It occurs in broad-leaved forests with fagaceous plants. It has been known from China and Japan. Amanita pseudogemmata is characterized by its yellowish to brownish yellow pileus with brownish grey to olivaceous brown verrucouse to farinose volval remnants; limbate to subtruncate basal bulb; inamyloid, broadly ellipsoid to ellipsoid spores; and the absence of clamps. The reader may wish to make comparison with A. gemmata (Fr.) Bertillon in Dechambre and A. orientigemmata> Zhu L. Yang & Yoshim. Doi. –- Zhu L. Yang |

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 not directly from the protolog of the present taxon and not cited as the work of Dr. Z. L. Yang or another researcher is based upon original research by R. E. Tulloss.

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.
