Catalogue of Life lists 3 accepted species:^[2]

Osteina obducta (Berk.) Donk

Description

Osteina is characterized by fruit bodies that are sessile to stipitate, which are bone hard when dry. It has a monomitic hyphal system, containing only generative hyphae with clamps. The spores are hyaline and thin-walled, and are inamyloid and acyanophilic. Osteina causes a brown rot in gymnosperm wood.^[3]
