Agaricus angusticystidiatus

Ciri dan struktur

Pileus 40–80 mm diam., plano-convex, applanate, broadly umbonate; surface concentric squamulose with small skull-cup at disc, appressed, slightly fissured, light brown (6D8), brown (7E3), greyish-brown (5D5), dark brown (6D6) against the grey (8E3) background. Context 4–5 mm thick at disc, fragile, white to grey (8E3) in age. Lamellae free, crowded, lamellulae with 3–4 lengths, 3–4 mm broad, normal to slightly ventricose, brown (7E5) to dark brown (7F7-8), edge colour similar to the gill itself. Stipe 55–100 × 5–8 (base 8–15) mm, cylindrical bulbous, with rhizomorphs in most cases, hollow, surface glabrous to silky, white to dark brown (6D6). Annulus pendent or percurrent; single; upper side membranous, white; lower side surface powdery, light yellow (4B2) grain-like dots in circulate; superior, persistent, edge entire, up to 5 mm broad. Smell of iodoform. No colour change on touching; light dull red, greyish brown (7D4) on cutting. KOH reaction: negative. Schäffer’s reaction: negative on dry specimens. Basidiospores 5–6.5 × 3–4 (–4.5) µm [X = 5.6 ± 0.5 × 3.8 ± 0.4, Q = 1.1–2.2, Q m = 1.52 ± 0.7, n = 20], cymbiform, some endosporium, no germ pore, brown. Basidia 10–15 × 5.5–7 µm, clavate, hyaline, smooth, 4-spored. Pleurocystidia absent. Cheilocystidia 20–30 (–45) × 5–8 µm, occasionally one septum, narrowly clavate to clavate, some with elongated top, rarely subcapitate, hyaline, smooth. Pileipellis cutis consisting of 3–5 µm diam. hyphae, hyaline, smooth, non-constricted at septa. Annulus hyphae same as pileipellis.
