Fig. 3 in The first record of Ulva adhaerens (Ulvaceae, Chlorophyta) from Jeju Island, Korea

Fig. 3. Ulva adhaerens Matsumoto & Shimada. (A) Natural habit of U. adhaerens from Munseom, Jeju, growing blossom-like attached on benthic invertebrates, seaweeds or sands. (B) The voucher specimen (MSK-GA00073) of U. adhaerens from Munseom, Jeju, Korea, Jan 30, 2013. Thallus habit composed blossom-like and dorsiventral lobes having rounded and slightly ruffled blade. (C) Marginal part slightly uneven without marginal denticulations or microscopic protuberances. (D) Sub-roundish to polygonal cells at the surface view of upper part with irregular arrangement. (E) More angular cells at the surface view of basal part with irregular arrangement. Pyrenoids are one or two per cell (white arrows). (F) Transection of blade at upper part composed of cuboidal cells with solid cell profiles. The height of both dorsal and ventral cells is similar. (G) Transection at middle part composed of cuboidal cells with solid cell profiles. Dorsal cells are slightly higher than ventral ones. (H) Basal transection composed of cuboidal cells with solid cell profiles. Dorsal cells are much higher than ventral ones. (I-K) Blade adherence by numerous and interwoven secondary rhizoids (black arrows). Blade adherence (black arrowheads) occurs at the basal part between dorsal plane of main blade and ventral plane of subsidiary one. Both secondary rhizoids originated from distromatic cells are fused to each other. (L-N) The development of minute rhizoidal holdfasts. Rhizoids are bud off from distromatic cells (black arrow) (L). Rhizoids are expanding through ventral cell plane downwardly (black arrows) (M). Fully expanded and interwoven rhizoids (black arrow) produce minute and disciform holdfast (black arrowhead) at the tips (N). Scale bars: B = 1 cm; C-H, L = 30 μm; I, J, N = 150 μm; K = 60 μm; M = 50 μm.
