“…Similarly, isolates of Callithamnion hooked (Dillwyn) S. F. Gray from disjunct north-eastern Atlantic populations were found to be completely interfertile and formed normal F1 gametophytes (Rueness & Rueness, 1982). Interfertility was also found (Spencer et al, 1981) between four isolates of C. byssoides Harvey from Massachusetts, New York, North Carolina and Georgia and with an isolate of C. halliae F. S. Collins from Texas. However, none of these strains were interfertile with an isolate of C. byssoides from Norway.…”

Plants of Gigartina teedii from the Mediterranean isolated into laboratory culture showed Polysiphonia-type life histories with consistent formation of dioecious gametangial plants, as previously reported for Atlantic isolates. Male and female plants from the Atlantic and Mediterranean were almost completely compatible in terms of cystocarp formation on female plants, and carpospores from positive crosses always formed plants that released viable tetraspores. Sex-linked inheritance of branching pattern was found in all strains, but showed varying degrees of expression. Female plants were more branched than male plants and it is suggested that this may be an adaptation for spermatial capture. G. teedii plants showed differences in morphology in culture that are considered to be genetically-based. Preliminary studies of tip elongation showed that Mediterranean strains may have up to three times the elongation rates of Atlantic strains at 15~ 16:8h. Such genetic variation in fully-interbreeding strains suggests that populations of this species in the Atlantic and Mediterranean are genecodemic. All strains showed an upper temperature tolerance of 31 ~ when tested at 1 ~ intervals from 29-34 ~ An upper temperature tolerance of 31-32 ~ was found for the related species G. intermech'a from Korea and Japan, but G. johnstonii from the Gulf of California showed an upper tolerance of 32-33 ~

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.

“…Questions have existed for some time as to whether North American specimens identified as Callithamnion byssoides Arnott ex Harvey (1833) should be labeled C. pseudobyssoides (Rueness and Rueness 1980;Spencer et al 1981).…”

who, in addition to other kinds of help, each read the rough draft of the manuscript and offered many crucial, critical, and constructive suggestions. Our editor was amazed at the detailed and careful work that they did. Errors of commission and omission have surely crept in since their reading, and for these we accept all responsibility. At the penultimate moment, Geoff Leister came forward to assist with the conversion of the manuscript to the software required for publication.We are also grateful to the curators and keepers of the herbaria that have made collections available to us. These include the Agardh Herbarium, Lund, Sweden;
