Agaricus flocculosipes

Agaricus flocculosipes R.L. Zhao, Desjardin, Guinb. & K.D. Hyde

Index Fungorum number: 561690

This species has middle to large sporocarps. When mature, the cap can be 9–18 cm in diameter; hemispherical to convex, plano-convex, and then planes with age. The surface is dry, smooth or can be covered by light brown or brown fibrillose squamose against a snow-white background. The cap usually has a pink to red tone in wet conditions. Lamellae are free, crowed, white when young but becoming pink, then brown and dark brown. The stipe is cylindrical with an abruptly bulbous, white base. The annulus is membranous and white. The

lower surface has a heavily floccose structure. Its heavily floccose stipe, almond odor and distinctly yellowish discolouration on both the cap and the stipe make this species easy to distinguish. (Fig. 1)


Time of fruiting: This species can be found throughout the entire rainy season: from May to September.

Habitat: Solitary, scattered, or gregarious on rich soil or heavily rotted wood in forests. Sometimes appears on vegetation waste.

Distribution: This is a recently described species, which was introduced from Thailand. It has not been reported in other countries yet.
