(From the naked pileus, owing to the usually obsolete veil;
Gr. psilos, naked, kube, a head.)
^ VeU very fugacious, usually obsolete. Hymenophore confluent

or less fleshy, smooth; the margin at first incurved. Stem central
fistulose or stuffed, subcartilaginous, rigid or tough, often rooting,
simple. Gills becoming fuscous, brownish or purplish. (Fig 46 )
Nearly all the species grow on the ground and are gregarious
and sometimes cæspitose, a few grow on dung ; they are inodorous
and none are edible.
