H. stellatum is a much more robust plant, and has entire leaves, and a dioicous inflorescence.

H. Sommerfeltii, Bryol. Europ. (H. polymorphism, Bryol. Brit.) approaches very closely to H. hispidulum; and, except the longer and narrower acumination of the leaf of the former, (which is hardly sufficient,) there appears to be no character to separate them.
