Taxonomic notes
John et al. (2004) cite Dasya arbuscula (Dillwyn) C. Agardh as a synonym of this species. Furnari et al. (2003) note that “although D. arbuscula (Brown ex Dillwyn) C. Agardh is a taxonomic synonym of Aglaothamnion sepositum (Gunnerus) Maggs & Hommersand, we follow Gómez Garreta et al. (2001) in considering Italian records of D. arbuscula as sensu Harvey. Therefore, they are here referred to D. hutchinsiae.”

On rocks or epiphytic, shady low intertidal pools and subtidal, southern and western coasts to Orkney Islands, occasional.
