The bryophytes of the Douglas Lake area of northern Michigan (including Cheboygan, Emmet, Mackinac, and Presque Isle counties) have recently been dealt with in detail by Arzeni (1950) and Crum (1964, 1965); but, particularly as a result of field work during the summer of 1965, several bryophytes can be added to the flora. These and other unreported species noted incidental to herbarium studies at UMBS and at the UM are presented here, together with previously published records of a number of liveworts which Arzeni apparently overlooked. In the following list, species preceded by an asterisk (*) are new to the flora.
