BRIEF DESCRIPTION

Amanita parcivolvata is a very common species of the southeastern U.S.A., occurring at least as far north as the Atlantic coastal plain in New Jersey. Its 30 – 70 mm wide cap is scarlet and has a strongly striate margin. The volva is distributed over the cap as powdery, yellow to pale yellow warts. The free gills are yellow in mass and white in side view. The short gills are truncate. The stipe is 20 – 43 x 10 – 13 mm, has no annulus and is covered with yellow, powdery remains of the volva. There is a 20 – 15 x 15 – 20 mm bulb at the stipe base. The spores measure (8.4-) 9.1 – 11.5 (-12.6) x (5.6-) 6.3 – 7.9 (-8.0) µm and are broadly ellipsoid to ellipsoid to elongate and inamyloid. Clamps are rare at bases of basidia. The species is associated primarily with oaks and pines. It bears some similarities to bright-colored, ringless species of Amanita sect. Amanita such as A. xanthocephala (Berk.) D. A. Reid & Hilton and A. aurantiovelata Schalkwijk & Jansen. — R. E. Tulloss Photos: R. E. Tulloss (South Carolina)
