Basidiocarps medium-sized, somewhat fleshy, pale ochre to ochre; stipe 3-10 mm wide; veil covering entire pileus when young, breaking up of small, woolly flocks (in C. bipellis in patches), microscopically of chains of cylindrical, ellipsoid, broadly fusiform or (sub)globose, hyalin, thin-walled and in part thick-walled and yellow-brown cells; terminal cells distinct, cylindrical, ellipsoid, ovoid or fusiform; pileus subglobose to ovoid, only tardily expanding to campanulate (subsect. Domestici Sing.).
