Discussion

Campylophyllum halleri is easily recognized by its strongly squarrose leaves and short acumina. Similarly strongly squarrose leaves occur in other pleurocarpous species, for example in some of the much larger species of Rhytidiadelphus, but not in other North American species of Campylophyllum. No type material of Hypnum macounii Kindberg was found among Kindberg collections in Stockholm.
