Amanita novinupta [ Basidiomycetes > Agaricales > Amanitaceae > Amanita . . . ] by Michael Kuo One of several "blushing" species of Amanita, Amanita novinupta is the western North American version of the European and Asian species Amanita rubescens--which may or may not be the same as the "Amanita rubescens" of eastern North America. Amanita novinupta is generally stockier than its eastern counterpart, and its cap is initially white. As it matures the cap begins to "blush," and pinkish areas develop, seemingly below a translucent surface. By maturity the cap can be pinkish to brownish. Description: Ecology: Mycorrhizal with hardwoods, especially coast live oak--and under conifers; fall, winter, and spring; California to British Columbia. Cap: 3-11 cm; round, becoming convex or nearly flat; dry; surface appearing dusted or chalky at first, later shiny or satiny; white at first, then developing pink shades that can seem to originate from beneath the translucent surface; eventually pinkish to tan; bruising and discoloring pale pinkish or darker reddish brown; universal veil taking the form of whitish to pale pink warts or one to several patches; the margin not lined, sometimes hung with a few veil remnants. Gills: Free from the stem or slightly attached to it; whitish; close or crowded; bruising pinkish. Stem: 2-15 cm long; 1-3 cm thick; slightly tapering to apex; usually with a prominent basal bulb; more or less smooth, or finely scaly; white; bruising pinkish to reddish; with a white, skirtlike ring; occasionally with a few universal veil remnants near the base, but without a prominent volva; solid or partially hollow in age. Flesh: White throughout; staining pinkish to reddish on exposure. Spore Print: White. Microscopic Features: Spores 8-11 x 5.5 - 7 µ; smooth; ellipsoid; amyloid. REFERENCES: Tulloss & Lindgren, 1994.
