Conocybe macrospora (GF Atk.)

Diagnosis fuente: 
     Pileus 5.0–30.0 mm, at fi rst campanulate, later conical-campanulate to campanulateconvex, slightly pubescent, soon glabrous, hygrophanous, striate almost to centre, moist brown, rust-brown, light brown to orange-brown, at margin slightly paler, on drying becoming pale brownish orange, orange- to ochraceous-yellow, at margin paler. Lamellale narrowly adnate to almost free, rather crowded (L = 15–25, l = 1–3(–7)), ventricose, up to3.0 mm wide, at fi rst pale brown, later light rust-brown to rust-brown, with paler fi nely fl occulose edge. Stipe 50.0–95.0 × 1.0–3.0 mm, cylindrical with slightly or clearly bulbous base (up to 5.0 mm broad), hollow, longitudinally pruinose-striate, at apex pubescentpruinose, at fi rst pale yellow in upper part, below darker, pale orange, to reddish brown at at fi rst pale yellow in upper part, below darker, pale orange, to reddish brown at base, later light brownish-orange, honey-brown. Flesh in pileus up to 1.5 mm wide, whitish to pale yellowish, in stipe darker, to orange-yellow. Taste and smell indistinct, sometimes with slight radish odour. Spore-print rust-brown.
     Spores (13.5–)16.0–19.0(–20.5) × (7.0–)8.0–10.5(–11.5) μm (n = 80), Q = 1.62–2.0; av. L = 18.0±1.28 μm, av. B = 10.0±0.82 μm, av. Q = 1.81±0.09; in front view ellipsoid to slightly limoniform-ellipsoid, in side view ellipsoid, slightly fl attened ventrally or somewhat amygdaliform, germ-pore central, up to 3.0 μm wide, thick-walled, yellow-brown in water, reddish-brown in alkali. Basidia 17.0–23.0 × 11.0–12.0 μm, clavate, 2-spored Cheilocystidia 15.0–26.0 × 5.5–10.0 μm, lecythiform, neck up to 3.5 × 2.5 μm, head 3.0–5.0 μm wide. Pleurocystidia absent. Pileocystidia cylindrical and hair-like, up to 85.0 × 2.5 μm, scattered or rather numerous. Caulocystidia of three types: a) 15.0–22.0 × 6.0–10.0 μm, lecythiform, neck up to 4.0 × 1.5 μm, head 3.0–5.0 μm wide; b) 9.0–16.0 × 6.0–8.5 μm, ellipsoid, globose-clavate and clavate; c) hair-like, up to 100.0 × 2.0 μm. Pileipellis hymeniform, consisting of spheropedunculate and pyriform elements 15.0–25.0 μm wide. Clamp connections present. Ammoniacal reaction negative.
Habitat and distribution. Solitary or in scattered groups on soil, sometimes on manured soil or burnt places, in frondose, coniferous and mixed forests, as well as in grasslands (meadows, pastures, roadsides), in summer and autumn.
