Discussion

A specimen of Rhytidiadelphus loreus from Owen Sound, Ontario (Moxley, July 1925, DUKE) is correctly determined, but the locality is very doubtful. In Quebec, R. loreus is known only from the Magdalen Islands in the Gulf of St. Lawrence. The branches of R. loreus decrease regularly in length distally on the stem.
