fritillaria (Berk.) Sacc.
Technical description (t.b.d.) BRIEF DESCRIPTION: Fruiting bodies of Amanita fritillaria are small to medium-sized, sometimes large. The cap is 40 - 100 (-120) mm wide, convex to applanate, greyish, brownish grey to brownish, darker over disc, innately fibrillose, and densely covered with dark grey to blackish, farinose, verrucose to felty volval remnants; the cap's margin is smooth and non-appendiculate; and the flesh is white. The gills are free, crowded, and white; the short gills are attenuate. The stem is 50 - 100 × 6 - 15 mm, subcylindric or attenuate upwards, with a surface that is white to dirty white and covered with greyish to grey squamules; the stipe's basal bulb is 10 - 25 (-30) mm wide, subglobose to ventricose, and has its upper part covered with dark grey to blackish, verrucose, floccose to farinose volval remnants. The ring is membranous, with an upper surface that is whitish to greyish to grey and a lower surface that is greyish to grey, or sometimes brownish. The spores measure 7.0 - 9.0 (-12.0) × (5.0-) 5.5 - 7.0 (-8.5) µm and are broadly ellipsoid to ellipsoid and amyloid. Clamps are not present at the bases of basidia. This species was originally described from India. It is widely distributed in China and also reported from Singapore. -- Zhu L. Yang Amanita fritillaria f. malayensis Corner & Bas Amanita fritillaria f. malayensis Corner & Bas differs in three characters; the spores are globose to broadly ellipsoid and 6.0 - 7.6 × 5.4 - 6.6 (-7.6) µm. Measured in the fresh state by Corner, 7 - 8 × 6.5 - 7.5 µm. The volva remnants on the cap are larger than on the type forma and the cap color is darker than in the type forma -- dark umber to pale greyish umber-fuscous over center. In both cases appearing virgate with comparably darker innate radial lines. -- R. E. Tulloss Photo: Zhu L. Yang. [ Section Validae page. ]
