Amanita silvatica Guzmán
"Guzmán's Tropical Amanita"
Technical description (t.b.d.) BRIEF DESCRIPTION: This description is based on the original description (1982). The cap of A. silvatica is 20 - 35 mm wide, convex to plane, slightly slippery when moist, yellowish orange to pale yellow toward the margin, glabrous, with sulcate-striate margin. The cap is scattered with irregularly shaped, yellowish, rather thick, floccose-membranous, flat patches from the volva. The flesh is white. The gills are free and white to cream. Short gills were not described. The stem is 35 - 45 x 3 - 7 mm, cylindric or narrowing upward, white to whitish cream. The basal bulb is globose or subglobose, white to pale cream. The stem is somewhat floccose in the lower part. A ring is absent. The volva is a free limb, white, sometimes with vertical splitting, with an yellowish-orange edge of the limb. The flesh is white. The spores measure (4.9-) 6.7 - 9.0 (-9.7) x (4.9-) 6.0 - 7.5 (-8.2) µm and are globose to subglobose and inamyloid. Clamps are absent at base of basidia. The mushroom was found growing on the soil of a tropical rainforest, subgregariously. Amanita silvatica was originally described from the state of Quintana Roo (Mexico) near the Caribbean sea coast. In the original description, comparison
to A.
elata
(Massee) Corner & Bas is suggested, however the evidence given
does not suggest a close relationship. Return to Section Amanita page. Last changed 2 June 2006. |
