Agaricus macrochlamys

Ciri dan struktur

Macroscopic description (Figure 3 and Figure 5): Pileus 3.9–13.7 cm diam., truncate-convex when young, then hemispherical to plano-convex, finally plane at maturity, usually with a slightly depressed center (never with prominent umbo); surface dull and dry, very variable in appearance and colors, mostly completely covered with brownish fibrils when young, becoming to fibrillose, slightly reddish or hazelnut-brown or violet-brown squamules over a white, grayish or beige background, denser at the disc, forming an entire brown to dark brown center, less towards the margin; in other cases, also completely white, whitish or very light cream with only the disc colored brown to dark brown; in these collections with pale or whitish pileus, the surface appears smooth or slightly fibrillose, in some collections, somewhat rough, never scaly. Margin always exceeding the lamellae. Lamellae free, crowed, up to 1 cm broad, intercalated with numerous lamellulae, white to pinkish when young, finally dark brown at maturity, with finely denticulate whitish edge. Stipe 4.6–14.9 × 0.5–1.6 cm, cylindrical, sometimes curved with bulbous to sub-bulbous base (1.5–3.5 cm wide), fistulose, with an annulus in its upper third, above the annulus smooth and below the annulus whitish or slightly rosaceous below, at first pruinose then smooth, with a pure white evanescent flocculosity towards the base, slightly yellowing on handling, sometimes with short white rhizomorphs at the base. Annulus attached to the upper part of the stipe, superous, pendent, very broad, fragile, membranous to fibrillose-araneose, double, upper surface white smooth to subtly striate radially, lower surface covered by 0.2–0.4 cm floccose-squamulose white or light brownish square patches (thicker toward the pileus margin, conspicuous in younger specimens).
