Diagnosis:—Similar to N. hygrophanus but differs from it by the dark brown spots on the pileus and the presence of pleurocystidia. Differs from N. nambi by the present of pleurocystidia, and N. gardneri by the presence of cystidia and size of basidiospores.
Type:— HMJAU 48222 View Materials .
Etymology:—‘cystidio’, refers to the species having pleurocystidia.
Description:— Basidiocarp annual, scattered or superposed, small to medium-sized. Pileus semicircular to circular, 1.5–3.3 cm diam, convex or slightly depressed at centre, white when young, becoming vinaceous buff when mature, dark brown spots appearing when mature, glossy, smooth, hygrophanous, translucent, and radially striate; margin white, entire, serrated or sometimes wavy and involute. Context white, thin, odourless. Lamellae not uniformly coloured, white to straw colour at the centre, white at the margin, decurrent, entire to wavy, thin, 1–3 tiers of lamellulae, non bifurcate. Stipe short, 0.3–0.5 cm long, and 0.2–0.6 cm diam, off-white to light pink, excentric to lateral, cylindrical or conical, smooth, solid, fibrous. Spore print unknown.
Basidiospores 4.8–6.1(–8.1) × 3.0–3.4 μm, Qm = 1.71 ± 0.24, subglobose to elliptical, smooth, hyaline in 3% KOH, inamyloid, thin-walled. Basidia 17–29 × 5–6 μm, clavate, hyaline in 3% KOH, thin-walled. Cheilocystidia absent. Pleurocystidia 13–30 × 3–6 μm, clavate to cylindrical, bulging at the top sometimes, hyaline in 3% KOH, thinwalled. Pileipellis hyphae 3–10 μm wide, hyaline in 3% KOH, thin- or thick-walled (up to 1.0 μm thick). Stipitipellis hyphae 2–9 μm wide, hyaline in 3% KOH, thin- or thick-walled (up to 1.2 μm). Lamellar trama subregular to regular, 2–10 μm broad, hyaline in 3% KOH, thin-walled. Clamp connections abundant in all tissues.
Ecology and distribution:—Growing on rotten wood, Ghana.
