Heterosiphonia plumosa, copyright kristobal22.

Belongs within: Ceramiales.

The Dasyaceae are a family of red algae exhibiting cellulosympodial growth and bearing whorled tetrasporangia in stichidia on determinal laterals (Choi et al. 2002).

Characters (from Choi et al. 2002): Growth cellulosympodial; tetrasporangia whorled, borne in stichidia on determinal laterals; pigmented pseudolaterals present, Y-shaped cell abutments at pseudodichotomies; trichoblasts absent; carposporophyte with basal fusion cell initiated by direct connection between auxiliary cell and fertile central-axial cell, at first bypassing supporting cell but ultimately incorporating it.
