Known only from the island of Madeira, Fissidens microstictus grew on basaltic rocks and was most common at altitudes of 78–313 m (256–1,027 ft) above sea level. It was recorded from just three sites in the parish of Monte, near Funchal.[3] This area is now fully urbanised due to increased tourism.[1][4]
