The members of this genus are leathery plants, with the stems lateral or wanting. The gills are simple, not forked, and the spores are white. Panus stypticus is common on rotter wood, and gives out a weird, phosphorescent light.
The species of the genus Panus so much resemble specie: of the genus Lentinus, which do not have toothed margins, that Panus and Lentinus are considered by some as one genus, with the name Lentinus.
