Specimens from the exsiccatae Phycotheca BorealiAmericana number 698 are shown to represent two distinct species. One of them, formerly known as Callithamnion halliae, is transferred to Aglaothamnion on the basis of its uninucleate cells. The specimens exhibit distichous branching and are ecorticate. A lectotype is proposed for one of the P.B.‐A. #698 specimens displaying these characters . Aglaothamnion halliae ( Collins) comb. nov. is an earlier name for Aglaothamnion westbrookiae Rueness et L'Hardy‐Halos. The second species, together with specimens of P.B.‐A. #1896, has radial branching and corticated axes and is described herein as a new species , Aglaothamnion collinsii. The binomial Aglaothamnion boergesenii ( Aponte et Ballantine ) L'Hardy‐Halos et Rueness in Aponte, Ballantine, et J. Norris is validated. A key to the tropical and warm‐temperate western Atlantic species of Aglaothamnion is presented .
