Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Hrabovsky et al. 2016 | Growth form encrusting, non-protuberant,
thallus 610784 mm thick, on other algae or on biogenic remains in multispecific rhodoliths (Fig. 5A). Thallus monomerous, with dorsiventral organization. VC up to 76 mm and eight cells thick. Cells rectangular to slightly trapezoidal, L 1516 mm £ D 78 mm (n D 10; Fig. 5B). PF zoned (Fig. 5B), with squarish to rectangular cells. Cells L 913 (15) mm £ D 810 mm (n D 38). Longest PF cells occur at the base of zones or on lateral side of the conceptacles. Cell fusions present in VC and PF (Fig. 5B). Layer of flattened and probably flared EC, L 34 mm £ D 45 mm (n D 7) observed above the conceptacles (Fig. 5C). Multiporate asexuate conceptacles with flat roof and floor, markedly protruding about 6576 mm above thallus surface (Figs 5A, 18A). Roof 56 cells (4650 mm) thick, without rim. Roof cells L 712 mm £ D 78 mm (n D 9), comparable to cells of the PF (Fig. 5D). Chambers 98135 mm H and 327498 mm D (n D 5). D/H is 2.73.3. Pore canals crossing the roof, about D 11 mm. |
