Agaricus augustus
Common: The Prince
Description: Cap 6-32 cm broad, convex expanding to plane; surface dry with yellow-brown to brown scales; Veil cottony patches, later becoming membranous, forming a skirt-like annulus; Gills close, free, pale pink at first, then blackish-brown at maturity; Stem 10-37 cm long, up to 6 cm thick, equal to enlarged at base, frequently buried; smooth above ring, scaly below; Flesh thick, firm, white, may discolour yellow when bruised; Smell sweet, anise or almond-like; Spore print chocolate-brown.
Habitat: Late summer & early fall, single or in groups or clumps on ground in deciduous or coniferous woods, gardens, roadside.
Primary keys: Yellow-brown scaly cap, sweet odor, blackish free gills, prominent ring.
Edibility: Choice: an excellent edible, one of the very best. A good drying mushroom.
Notes: One our largest (one foot diameter & one pound) and most spectacular Agaricus species. Since it's common in landscaped areas, be wary of chemical treatements and heavy metal bioaccumulation. Unfortunately it is frequently infested with fly larvae. If so, bring those home and inoculate your fresh landscaping!
