Laccaria umbilicata

Ciri dan struktur

Basidiomata small. Pileus 7–11 mm in diam., applanate to plano-concave, depressed to subumbilicate shape of center, light yellow (1B4), when loss of moisture or with age becoming whitish, clearly striate towards the margin on the surface, without umbo; margin straight, eroded of margin; context thin, 0.5–1 mm, light yellow (1B4). Lamellae reddish brown (8E5–8), 3–5 mm wide; lamellulae subdecurrent to decurrent, thick, regular, distant, 3–4 mm in height; lamella edge even or entire, sometime undate, lamellulae in 3–4 tiers. Stipe 11.0–18.0 × 1.4–2.0 mm, cylindrical, fistulose, central or eccentric, equal with an enlarged base and nearly subclavate, white (1A1), sometime pale orange, basal mycelium white (1A1); stipe context fistulose, white, sometime pale orange. Odor and taste not observed. Basidia 30–49 × 9–15 μm, (mean length = 39 ± 6.3, mean width = 12 ± 1.9), clavate, hyaline, 4-spored; sterigmata 5–8 × 2–3 μm (mean length = 6 ± 0.7, mean width = 2.5 ± 0.23). Basidiospores (excluding ornamentation) [150/3/2] (6.4–) 7.9–11.0 (–12.0) × (5.7–) 7.4–9.6 (–10.8) μm, (mean length = 9.4 ± 0.76, mean width = 8.9 ± 0.73), Q = 1.00–1.34, Q m = 1.07 ± 0.06, globose to subglobose, hyaline, echinulate; spines 0.2–0.5 μm long, ca. 0.5–0.8 μm wide at the base, crowded. Cheilocystidia 15–20 × 3–5 μm, (mean length = 17 ± 1.7, mean width = 4 ± 0.8), subclavate, narrowly clavate, hyphae-like, flexuose or mucronate, thin-walled, hyaline, abundant. Pleurocystidia 17–25 × 4–6 μm, (mean length = 20 ± 2.6, mean width = 5 ± 0.7), subclavate, narrowly clavate, hyphae-like, flexuose or mucronate, thin-walled, hyaline, abundant.
