Osteina obducta is a fungal species in the family Dacryobolaceae. The genus and species was circumscribed by mycologist Marinus Anton Donk in 1966, making Osteina obducta the type species.
Osteina obducta 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 obducta causes a brown rot in gymnosperm wood.
Osteina obducta is inedible.[1]
