Amanita chlorinosma [ Basidiomycetes > Agaricales > Amanitaceae > Amanita . . . ] by Michael Kuo Amanita chlorinosma is one of several white species of Amanita with powdery universal veil remnants and a strong, peculiar odor that is reminiscent of chlorine--although the name chlorinosma often gets applied in a broad, field-guide-ish sense to almost any species meeting this description. Strictly speaking, however, the name should probably be reserved for a small to medium-sized, oak-associated species of eastern North America with a slight basal bulb and a very thick, powdery veil. Description: Ecology: Mycorrhizal with oaks and perhaps with pines; usually growing alone, but sometimes growing scattered or gregariously; summer and fall; widely distributed in eastern North America below the Great Lakes from about the Mississippi River eastward. Cap: 2.5-10 cm; convex, expanding to planoconvex or flat; dry; white; covered with thick, white to grayish, powdery universal veil material (usually as an indistinct powdery or mealy layer, but sometimes as well defined patches, or even aggregated into a few clearly defined warts); the margin not lined. Gills: Free from the stem or slightly attached to it; close; white to ivory; with frequent short-gills. Stem: 5-10 cm long; 0.5-1.5 cm thick; more or less equal above a slight basal bulb; sometimes with a short, rooting, underground portion; white; covered with veil material like that on the cap; usually lacking a ring; volva powdery and indistinct. Flesh: White; not staining on exposure. Odor: Strong and somewhat foul; reminiscent of chlorine and rotting meat. Chemical Reactions: KOH on cap surface negative to slightly yellowish. Spore Print: White. Microscopic Features: Spores 7-11 x 5-7 µ; ellipsoid; smooth; amyloid. Basidia 4-spored; basally clamped. Pileipellis a cutis of elements 2-9 µ wide. Lamellar trama bilateral; subhymenium with inflated cells. REFERENCES: (Peck, 1878) Lloyd, 1898. (Kauffman, 1918; Bas, 1969; Smith, Smith & Weber, 1979; Jenkins, 1986; Tulloss, 2013.) Herb.
