“…Major differences in thallus size and habit separate E. foliiformis from Porphyra woolhousiae as described by Womersley and Conway (1975). The unusual stellate filamentous stages of E. foliiformis described here isolate the species from any other entity except Boidia (Herndon 1964;Nicholls 1964), for which similar structures have been described. The filaments of Boldia, however, do not initiate or grow in the same manner as in E. foliiformis and push between the cell walls; they ultimately give rise to monospores (Herndon 1964) a function not seen in our species.…”

“…The blades of E. foliiformis are likewise readily distinguishable on morphological, developmental or reproductive grounds from those of Porphyra C. Agardh ( 1824) and Porphyrella Smith and Hollenberg ( 1943) (Bangiaceae); of Smithora Hollenberg (1959) and Membranella Hollenberg and Abbott (1968) (Erythropeltidac~ae); and of Boidia Herndon (1964) …”

“…Confusion with Boldia, a freshwater genus, is eliminated as it produces persistently saccate thalli (Herndon 1964;Nicholls 1964). The down-growing basal rhizoids distinguish E. foliiformis from Membranella (Hollenberg and Abbott 1968) and Smithora (Hollenberg 1959), which lack such structures.…”

Previous records of Porphyropsis from New Zealand are assigned to Erythrotrichia folii/ormis sp. nov. (Rhodophyta, Erythropeltidaceae). Occurring as minute epiphytes on Marginariella boryana (Rich.) Tandy, Lessonia variegata J. Ag. and Macrocystis pyrifera (L.) C. Ag., the plants show affinities with the polyseriate Erythrotrichia species, but by their possession of a rhizoidal attachment organ must be placed close to E. vexillaris (Mont.) Hamel. Filamentous stages of unknown function, which develop in situ on the blades of E. folii/ormis, appear to be unique in Erythrotrichia.

“…The length of bulbous fronds seldom exceeds 4.0 cm at maturity. This bulbous saccate morphology was first associated with specimens of Boldia from Big Walker Creek (Herndon, 1964). Loss of an apical cell following the initiation of a hollow frond often results in a branched thallus (Fig.…”

Collection and study of the freshwater red alga, Boldia, from 10 previously unreported habitats disclosed specimens not assignable to either of the two established species. Boldia angustata Deason and Nichols is reduced to synonomy with the earlier described B. erythrosiphon Herndon because of significant overlap between the specific characteristics. Boldia erythrosiphon Herndon emend Howard and Parker is a pleomorphic alga with a more widespread distribution than previously recorded. It is perennial, alternating between an erect saccate frond and prostrate filaments, and both phases are linked by a basal holdfast of pseudoparenchymatous or filamentous construction. Sexual reproduction was not observed; however, asexual reproduction resulted from monospores released by mature fronds, which then germinated to produce basal structures, and through the initiation of erect uniseriate filaments eventually formed new fronds. Absolute growth requirements were not determined; however, similarities in habitats, specifically the abundance of other red algal genera and a predominance of manganese in both snail and rock substrates of Boldia, suggest an interaction of stream temperature, chemistry, substrate, and photoperiod as limiting the distribution of Boldia erythrosiphon.

“…Parker is a red freshwater macroalga described by Herndon (1964) and since then found in more than a dozen streams, primarily in the southeastern United States (Howard and Parker 1980) but as far north as central Quebec (Sheath et al 1989). The species represents a monotypic genus within the monotypic Boldiaceae, and its morphological plasticity led to the description of a second species, B. angustata (Deason and Nichols 1970), which later was reduced to synonomy by Howard and Parker (1980).…”

The nuclear small‐subunit ribosomal DNA sequence from the freshwater red alga Boldia erythrosiphon Herndon emend Howard et Parker was determined. Phylogenetic analysis confirms the positioning of this species within the bangiophycidean order of the Compsopogonales. The results strongly suggest that occupation of freshwater habitats by marine red algae has happened at least twice during red algal evolution.
