FIG. 2 in A taxonomic assessment of Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov. (Bangiaceae, Bangiophyceae)
FIG. 2. — Herbarium specimens of the isolates of Porphyra linearis Greville and Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov.: Porphyra linearis from Ireland (Waterford, GALW01138), Germany (Helgoland, GALW011343), Portugal (Viana do Castelo, GALW011351) and Sweden (Lyckeby, GALW011347); Py. hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov. from Sweden (Amundon, GALW011329, epitype of the species). Scale bar: 1 cm.
FIG. 1 in A taxonomic assessment of Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov. (Bangiaceae, Bangiophyceae)
FIG. 1. — Porphyra linearis Greville and Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov.: A, lectotype of Porphyra linearis (Sidmouth, E!) which is the most similar specimen to the illustration (pl. XVIII: fig. 1, right) that Greville presented in 1830 in his Algae Britannicae chosen from the exicata of Porphyra linearis in Greville's collection at the Royal Botanical Garden, Edinburgh (E!); B, lectotype of Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov., here designated,Algae Scandinavicae Exsiccatae (Areschoug) kept at UPS in Sweden. Scale bars: 1 cm.
FIG. 3 in A taxonomic assessment of Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov. (Bangiaceae, Bangiophyceae)
FIG. 3. — Neighbour-joining phylograms: A, NJ Phylogram based on the rbcS-rbcL spacer and adjacent regions (333 nt) from 12 bladed Bangiales; B, NJ Phylogram based on a shorter rbcS-rbcL spacer and partial rbcL region (146 nt) of 14 blade Bangiales taxa. Both analyses include isolates of Porphyra linearis Greville and Pyropia hiemalis (Kylin) Varela-Álvarez, Guiry & Serrão, comb. nov. For each node, 10 000 replicates bootstrap values for NJ and also ML analyses are given using the Jukes-Cantor model. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. Symbols: *, distinct sequences produced in this study; **, species nomenclature according to Santiañez & Wynne 2020, Yang et al. 2020 and Zuccarello et al. 2022.

FIGURE 9 in A new species of Pyropia (Rhodophyta, Bangiaceae), from the Pacific coast of Mexico, based on morphological and molecular evidence
FIGURE 9: Bayesian result for concatenated nuclear SSU ribosomal RNA (nrSSU) and rbcL data set. Support values are Bayesian posterior probabilities, and parsimony and distance bootstrap values, respectively. Some internal support values are omitted for clarity.

FIGURE 9 in Pyropia orbicularis sp. nov. (Rhodophyta, Bangiaceae) based on a population previously known as Porphyra columbina from the central coast of Chile
FIGURE 9. Maximum Likelihood (ML) rooted tree for rbcL sequences (876 bp) of Pyropia. Porphyra mumfordii, Porphyra purpurea and Porphyra umbilicalis were used as outgroups. For each node, ML bootstrap values and Bayesian Posterior Probabilities are indicated (ML/BPP). Only high support values (>60) are shown; '-' = clade not observed in the Bayesian Inference. Next to collapsed branches are abbreviated species or sequences names, GENBANK accession numbers have been omitted for brevity but are listed in Table 2. Regions where specimens were collected are indicated within parenthesis: SA = South Atlantic, SP = South Pacific, SO = Southern Ocean. Thick lines highlight the southern hemisphere clade that includes Pyropia orbicularis sp. nov.
