B. atropurpurea was first found on the southwestern shore of Lake Michigan [USA] in 1968; by 1976 it had covered suitable substrates on the southern 2/3 of the lakeshore. Optimal vegetative growth occurred above the low waterline during the spring and fall, especially near harbor areas. Vegetative growth was initiated from either perennating basal cells or monospores. Bangia contained extraordinarily high concentrations of Br and Zn, suggesting that it required relatively high levels of halogens and trace metals, which were present in runoff waters and contaminated harbors.
