In a study of the bryophytes of a series of six limestone sinks located in Alpena County, Michigan, 110 species were collected. Of these, no previous reports for the State of Michigan are known for Mannia siberica, Seligeria calcarea and Tritomaria scitula. The distributions of various bryophytic species are correlated with conditions in the individual sinks.
