Agaricus subrufescens

Ciri dan struktur

Macroscopic description (Figure 7): Pileus 5.3–11 cm diam., conical, then hemispherical or trapezoid, finally plano-convex, sometimes depressed at the disc, background whitish covered by fine hazelnut-brown, reddish-brown, brown-violet fibrils becoming squamules toward the disk, forming an entire densely reddish-brown center. Surface dull and dry, slightly yellowing on handling. Margin exceeding the lamellae, even in mature basidiomata. Lamellae free, crowded, straight, 0.6–0.8 cm broad, intercalated with numerous lamellulae, at first white (pinkish on handling, resembling a Leucoagaricus sp.), then pale pink for a long time, finally dark brown in mature basidiomata, with even and concolors or finely denticulate edge. Stipe 9–16 × 0.7–1.4 cm, cylindrical, sometimes curved at the base, enlarged, bulbous or abruptly marginate bulbous at the base (1.6–2.6 cm), fistulose, with an annulus in its upper third; above annulus white and smooth, below annulus white, pruinose when young, frequently covered by a white floccosity particularly towards the base; slightly yellowing on handling. At times with a single thick rhizomorph at the base. Annulus superous, double, white, fragile and fine, upper surface smooth to fibrillose-cobweb, lower surface covered by white or ochre floccose to wooly-floccose radially arranged square patches. Context in pileus and stipe firm, when cut white, sometimes slightly yellowing, with strong odor of anise. Microscopic description (Figure 8): Spores (4.3–)4.6– 5.3 –6.2 (–6.9) × 3– 3.8 –4.5(–4.9) μm, Q = 1.21– 1.40 –1.67, ellipsoid, brown, thick-walled. Basidia tetrasporic, clavate to broadly clavate, hyaline, thin-walled, 13–18 × 5.5–8 μm, sterigmata up to 2 µm long.
