Discussion
Stegonia hyalinotricha has the whitish leaves of Bryum argenteum and may be mistaken for that common weed, but the capsules are immersed and indehiscent. It was treated as Phascum hyalinotrichum by R. H. Zander (1994r). In this species, the abaxial walls of laminal cells are not differentially thickened.
