Conocybe siliginea (P.) Kühner

Diagnosis fuente:
     Pileus 3.0–17.0 mm, at fi rst campanulate or conical, later campanulate-convex, conical-convex, hemispherical to convex, smooth, light brown, pale brown, ochraceous, somewhat darker at centre, hygrophanous, not translucently striate, on drying becoming pale ochraceous, cream or whitish, at centre ochraceous. Lamellae narrowly almost free, rather distant (L = 20–25, l = 1–3), ventricose, up to 2.0 mm wide, at fi rst pale ochraceous, later light yellow-brown to orange- brown, with paler fi nely fl occulose edge adnate or Stipe 20.0–95.0 × 1.0–1.5 mm, cylindrical with clavate, sometimes slightly swollen base, hollow, longitudinally pubescent-striate, at fi rst white, later darkening from base upwards to whitish with brownish tinge or pale brown. Flesh in pileus up to 1.5 mm wide, whitish with ochraceous-brown hue, in stipe pale ochraceous-brown, at base brownish. Taste and smell indistinct. Spore-print rust-brown.
     Spores (9.5–)12.0–16.5(–17.5) × (6.5–)8.0–10.5(–11.0) μm (n = 40), Q = 1.20–1.86; av. L = 14.3±1.25 μm, av. B = 9.0±0.69 μm, av. Q = 1.59±0.1; in front view ovate-ellipsoid, narrowly ellipsoid and ellipsoid, in side view ellipsoid, slightly fl attened ventrally, sometimes somewhat amygdaliform, germ-pore 2.0–3.0 μm wide, thick-walled, light honey-brown in water, rust-brown or reddish brown in alkal. Basidia 14.5–36.0 ×8.0–12.0 μm, clavate, 2-spored, sometimes 1-spored occur. Cheilocystidia 14.5–31.0 ×6.0–12.0 μm, lecythiform, neck up to 4.0 × 2.0 μm, head 3.0–4.5 μm wide. Pleurocystidia absent. Pileocystidia hair-like, up to 75.0 × 2.5–3.5 μm, scattrerd to fairly numerous, cylindrical, utriform and lageniform, numerous; b) hair-like, up to 220.0 × 1.5–2.0 μm, moderately numerous. Pileipellis hymeniform, consisting of sphaeropedunculate and pyriform cells 16.0–30.0 μm wide. Clamp connections present. Ammoniacal reaction negative.
Habitat and distribution. Solitary or in small groups on soil, sometimes on manured soil or burnt places, usually in grasslands (meadows, pastures, roadsides, in steppes), sometimes in forests, spring–autumn.
