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.”
