Chlorophyllum demangei

Ciri dan struktur

Pileus small to medium-sized, 2.5–8.5 cm in diam. (Figure 3B), umbonate, white to cream coloured, covered with concentrically arranged, ochraceous to yellowish-brown squamules; margin finely striate. Lamellae free, white to cream-coloured, 5–7 mm in height. Stipe 5–6 × 0.2–0.5 cm, whitish, becoming yellowish to brownish on bruising, slender, annulus 1–1.5 cm below apex of the stipe, persistent. Context of pileus and stipe white, becoming reddish, pinkish or orange red when cut, thin in pileus. Spore print white. Basidiospores [45/2/1] (7.5) 8.0–10.0 (12.5) × (5.0) 5.5–7.0 (7.5) μm, 8.7 ± 0.4 × 6.3 ± 0.3 μm, Q= (1.3)1.4–1.7 (1.8), Qav =1.5 ± 0.09; ellipsoid, hyaline, strongly dextrinoid, slightly thick-walled, apex lacking germ pore but somewhat thinner than other areas. Basidia 25–30 × 7–9 μm, clavate, 4-spored. Squamules on pileus (pileus disc of the smaller slice of the holotype) composed of clavate to narrowly clavate cells, 45–66 × 11–15 μm, hyaline to very pale brownish in KOH. Clamp connections not observed.

Habitat dan peran ekologis

Saprotrophic, solitary to scattered, terrestrial. The distinctive characters of Chlorophyllum demangei are the discolouration of basidiocarps when bruised, the ellipsoid basidiospores without a germ pore and the pileal squamules composed of clavate to narrowly clavate elements. From the examination of specimens newly collected from southern Yunnan in China, not far away from the locality where the type of Lepiota demangei was collected, the distinctive characters were found that fit the description of Lepiota demangei (Yang 2000) very well. Thus, Lepiota demangei is transferred from Lepiota to Chlorophyllum.
