Pilosace spadiceus (Schaeff.) Kuntze: 504 (1898)

Pileus 3..0 – 8.0 cm in diameter, dark brown to chocolate brown when moist, , fading to pale buff, fleshy, globose, convex then plane to broadly umbonate,surface hygrophanous, glabrous.

Stipe length 4.0– 8.0cm × 0.5– 1.0 cm in diameter, white, discolouring to reddish-brown towards the base,cylindrical,slightly curved, fibrous-fleshy, fistulose, with a white mycelial base, veil absent. Lamellae  white to pinkish, finally purplish- brown,adnate-sinuate, edge white, pruinose. Spores 7.5 – 10.0 × 4.0 –5.2µm, oblong to ellipsoid, with athin-pale, reddish brown wall and a minute germ-pore. Basidia 4-spored, clavate in shape.Lamellae edge sterile with crowded cheilocystidia having a thick wall and crystalline encrusted mucronate apex. Pleurocystidia venticose fusoid, mucronate, apically encrusted, hyaline with a thickened wall , particularly towards the apex.

Ecology and distributionHomophron spadiceum is  found  North America, Central Europe, Asia, Africa, South America (Guzmán 1970, Sulzbacher et al. 2013) and Brazil (Gurgel et al. 2008, Montagner et al. 2015), Mexico (Guzmán et al. 2013) and Argentina (Nouhra et al. 2012). Presently, it has been reported from Mount Abu, Sirohi district of Rajasthan and was found growing alone, scattered, or gregarious, widespread after rainfall and is ectomycorrhizal with gymnosperm trees like Pinus roxburghii and Grewellia robusta.
