Porphyra corallicola was described based on a filamentous red alga inadvertently introduced into culture from a crustose coralline alga. This species is known only in its sporophyte (Conchocelis) stage, being possibly asexual and lacking the charismatic and “collectable” gametophyte stage. Consequently, little is known of its range and distribution...

Eisenia arborea Areschoug is a temperate kelp first described from California, and commonly reported as far south as Mexico. Floristic surveys in cold-temperate waters of the Northeast Pacific, however, have revealed its presence on the Canadian archipelago of Haida Gwaii (at latitude 53.3799o N), last reported from the area in 2000 by Sloan and Ba...

The current manuscript is the first in a series intended to publish accumulating DNA barcode data to make them accessible to the scientific community. Focused on 135 specimens of red algae from the remote islands of Tristan da Cunha, part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, the 47 (possibly 48; see not...

... The conchocelis has been observed to actively burrow within various calcium carbonate substrata and utilize differing seasonal cues (e.g., photoperiod and temperature changes) to trigger conchosporogenesis (Drew-Baker, 1949;Dring, 1967;Hawkes, 1978;Lindstrom et al., 2008;Waaland et al., 1990;Wang et al., 2020). Although euendolithic Pyropia nereocystis conchocelis has been observed within barnacle shells (Hawkes, 1978) and coralline crusts (Saunders & Brooks, 2023), general distribution and dispersion of the conchocelis of all bladed Bangiales remains cryptic (see Akpan & Farrow, 1984;Martínez, 1990;Saunders & Brooks, 2023;Tribollet et al., 2017). Bull kelp canopy initiation, or the timing in which hosts of P. nereocystis reach the canopy, occurs in the summer, and P. nereocystis utilizes a unique "dual daylength" winter photoperiod followed by summer photoperiod cue before conchosporogenesis and release (Dickson & Waaland, 1985). ...
... Interestingly, this was also the most common CIE in British Columbia, suggesting that these two closely related species may prefer crustose coralline algae as habitat for their Conchocelis stages. As Porphyra mumfordii is a Pacific species (although see [19]) and P. linearis an Atlantic species, we have used this biogeographical pattern to make tentative species assignments (Table 1 and Figure 3). While we have collected the gametophyte stage of P. mumfordii widely in British Columbia from the intertidal, we have only collected Porphyra linearis during winter in the intertidal at a few exposed locations [18]. ...
