| Amanita murinacea Pat. "Malagasay Mouse-Colored Death Cap"
Technical Description. (t.b.d.) BRIEF DESCRIPTION: The following description is base on Gilbert (1941) and the notes with the type collection. The cap of Amanita murinacea is 70 - 80 mm wide, dry, silky, mouse-gray, plano-convex, with a smooth margin. Volval remnants are absent. The gills are crowded, free, white. The stem is 95 × 13 mm, cylindric, narrowing upward, with a bulbous base. The ring is rather narrow, white, striate above, skirt-like. The volva is membranous, limbate. The bulb is ovoid and 30 x 20 mm, white, tends to turn fulvous. The spores measure 7 - 8 × 6 - 7 µm and are subglobose and amyloid. Gilbert's (1941) drawings of spores sometimes do not match the information provided in his descriptions. Measuring the spore drawings yields a length of 7.8 - 8.5 µm. Very few spores are positioned in side view and these show the widths to be 7 - 8.3 µm. Basidia probably lacking clamps because of its assigned section. Originally described from Madagascar, Africa in sandy soil. Gilbert (1941) believed this species was quite similar to Amanita alliodora Pat. -- R. E. Tulloss Return to Section Phalloideae page.
