Lepidocystis is a Palaeozoic genus of imbricate lepidocystoid eocrinoid, closely related to Kinzercystis , ^{[1] [2]} It bore a stalk, with which it attached to firm substrates; ^[3] and brachioles arising as lateral branches from its arms. ^[4]

It is only known from the late Botomian = Cambrian Series 2 Kinzers Formation. ^[5]
