Description: Basidiomata small to large. Pileal surface white to colored, usually paler toward margin; smooth or coarse, squamulate or smooth, rimose radially; margin striate, often splitting radially when mature, usually with protruding perforatorium, but absent or indistinct in a few species. Lamellae free, white at first, becoming cream or pinkish when mature, crowded, with lamellulae. Stipe central, usually cylindrical and more or less thickening close to the ground, surface white, smooth or squamulate, annulate or not, solid, fibrous, consisting of longitudinally parallel thin-walled hyphae. Pseudorhiza mostly present, rarely absent, tapering or cylindrical, connected to termite combs, surface pale or dark colored, striate; solid or hollow, fibrous, leathery or cartilaginous. Partial veil present or not, membranous if present, ephemeral in most species, and sometimes persisting as an annulus and squamules. Context white, fleshy, of thin-walled, inflated hyphae. Basidiospore deposit pinkish or cream, ovoid to ellipsoid; surface smooth; thin-walled and subhyaline, inamyloid. Basidia clavate, thin-walled and subhyaline with 4 sterigmata. Cystidia present or not, usually clavate to pyriform, few fusiform, rarely septate; smooth; thin-walled and hyaline. Clamp-connections absent. (Wei et al. 2009)
