Epiphytic on a wide variety of algae, and epilithic on bedrock and pebbles, on damp surfaces near extreme low water and in pools up to mid-tide level, occasionally on strongly wave-exposed shores, more frequently at moderately to extremely sheltered sites, particularly those with some tidal currents (Maggs & Hommersand 1993). Common near low tide level and in wave-washed pools, on rock or epiphytic (especially on Haliptilon (Womersley 1998). - (4 Jun 2010) - Wendy Guiry
