Figures & data
Table 1. Species included in the phylogenetic analysis with associated data.
Fig. 1. 50% majority rule consensus tree derived from Bayesian inference. Support values on branches are posterior probabilities, bootstrap support from maximum likelihood, and bootstrap values from parsimony. Bootstrap values below 50 are indicated with a dash. The two new species are shown in bold. For details of other taxa included in the analyses see .
Figs 2–6. Ulvella elegans. 2. Mature plant with a pseudoparenchymatous central area and mutually free distal filaments. 3. Young plant of radiating filaments of cylindrical vegetative cells with a single pyrenoid. 4. Same plant as in shown in different focus. 5. Barrel-shaped mature and empty sporangia. 6. Germlings. Scale bars = 20 µm (–) and 10 µm (, ).
Figs 7–12. Ulvella islandica, morphology of heterotrichous plants in culture. 7. Tuft of broad cylindrical filaments with rounded cells at the base. 8. Basal part of tuft with rhizoid-like filaments. 9. Vegetative cell with a parietal chloroplast and one pyrenoid. 10. Acrochaete-type hair. 11. Cylindrical, apical sporangium. 12. Germling with evacuated spore-wall attached. Scale bars = 20 µm (, ) and 10 µm (–).
