AMANITA VERNA var. DECIPIENS Trimbach

Description:

The cap of Amanita verna is 45 - 65 mm wide, white, yellow-ocher in the center, at first Hemispheric with a flattened center, then convex, finally nearly planar, smooth, shiny, slightly viscid when moist, drying quickly becoming satiny, with a nonstriate and nonappendiculate margin. The flesh is white, about 3 - 5 mm thick over the stem, and relatively firm. Gills are free at maturity, white to cream white, up to 6 mm broad, somewhat uneven on the edges, with a finely flocculent edge in young specimens. The short gills are subtruncate for the most part, some are sharply truncate. The stem is 85-105 x 7 - 13 mm, Cylindric, white, stuffed then hollow, smooth with fine scales, with a soft round bulb at the base. The ring is membranous, thin, skirt-like, persistent, with a few vague striations on the upper side. The volva is Limbo, white, membranous, arising from the top of the bulb, lacking an internal limb, with the top of the limb 25 - 30 mm from the top of the bulb. The odor is lacking at first then a little disagreeable. Spores from those specimens that become yellow in KOH solution measure (8.0-) 8.2 - 11.0 (-11.9) x (5.7-) 6.0 - 7.5 (-8.5) and are broadly ellipsoid to ellipsoid, infrequently Elong and amyloid, according to RET's observations . Clamps are absent at bases of basidia the. Spores measured by Neville and Poumarat are as follows: (8-) 9 - 11.5 (-12) x (5.5-) 6 - 8.5 (-9.5) and are subglobose to broadly ellipsoid to ellipsoid, infrequently Elong and amyloid. Amanita verna is deadly poison.
