DISTINCTION OF SOUTH AMERICAN HAPLOGLOIA ANDERSONII AND CHORDARIA LINEARIS (PHAEOPHYCEAE) BASED ON DIFFERENCES IN SEXUAL REPRODUCTION, MORPHOLOGY, ECOPHYSIOLOGY, AND DISTRIBUTION 1

ABSTRACT Haplogloia andersonii (Farlow) Levring is an anti‐tropical species that occurs on cold and warm‐temperate Pacific coasts of both Americas. In its habit it resembles the subantarctic species Chordaria linearis (Hooker et Harvey) Cotton. Culture studies show that the species differ in morphol...

Description
Summary:ABSTRACT Haplogloia andersonii (Farlow) Levring is an anti‐tropical species that occurs on cold and warm‐temperate Pacific coasts of both Americas. In its habit it resembles the subantarctic species Chordaria linearis (Hooker et Harvey) Cotton. Culture studies show that the species differ in morphology and ecophysiology of their microscopic gametophytes and in gamete behavior. Details of sporophyte anatomy are presented that also allow the distinction of field plants. In South America, H. andersonii occurs only on the Pacific coast, from central Perú (14°S) to southern Chile (50°S). Chordaria linearis occurs on the Pacific coast from Chiloé Island (43°S) to Cape Horn (56°S). In the shared area the species may co‐occur. On the Atlantic coast, C. linearis was newly collected at a locality in northern Patagonia (41°S). In addition, C. linearis occurs in Antarctica. Haplogloia moniliformis Richer, recently described from Macquarie Island, is probably synonymous with Chordaria linearis .
