Distributional note
Nielsen & Gunnarsson (2001: 92) record this species as being an excluded species for the Faroe Islands. "Finally, agreeing with Gómez Garreta et al. (2001: 446), we think that Mediterranean records of Callithamnion decompositum J. Agardh [= Compsothamnion decompositum (J. Agardh) Maggs et L%u2019Hardy-Halos, taxon excludendum], are misidentifications with A. tripinnatum. Consequently, we consider Compsothamnion decompositum as a taxon excludendum." (Cormaci & al. 2023: 312). - (11 May 2006) - M.D. Guiry
