Photographed by Dave Genney at Achnahaird. Comment from David Long: These are male plants which have the androecial scales closely overlapping in multiple rows, unlike M. hibernica where they are not overlapping and are in two rows along the mid line of the thallus. M. flotowiana is typical of lowland fens and dune slacks, M. hibernica is in montane neutral to mildly basic flushes and on wet cliffs.
