Frost's Amanita

Some of the species' notable physical characteristics, however, distinguish it from the other members of the genus. For instance, the colors of the cap, darkening over the disk, and the universal veil, colored yellow to cream. The other characteristics of the other parts of its body are as follows:

Cap : The cap is convex or sometimes shield-shaped, becoming flat with a fairly distinctly lined margin. The cap may vary in lengths of 2–8 centimetres (1–3 inches). The colors include yellow to golden orange or a different combination of scarlet or deep reddish pink. The surface is smooth, becoming slightly sticky when moist. Stem/stipe : The stem, also called the stipe. The universal veil material is yellow to cream, forming yellow powder or flakes at the base of the stalk. It measures 47 to 62 millimetres (2 to 2+1⁄2 in) in length, and 4 to 11 mm in diameter, also consisting of a persistent annulus. Gills : The gills are free, close, and cream in mass. The short gills are truncate to excavated-truncate and are numerous. Spores and microscopic features : The spores measure 7.0 to 10.2 μm wide and are globose to subglobose and inamyloid. It has also been noticed that the spores of this mushroom do not turn black in color if iodine is poured on them.
