Calliblepharis jolyi E.C. Oliveira , Nova Hedwigia 18: 770 (1969). ( Figs. 2–3 View FIGURE 2 View FIGURE 3 )
Homotypic synonym:— Craspedocarpus jolyi (E.C. Oliveira) C.W. Schneider, Phycologia 27: 8 (1988).
Type locality:— BRAZIL. Espírito Santo: Itaoca Beach, 29 July 1965, coll. E. C. Oliveira Filho & A. B. Joly (Holotype SPF 2601!).
Vegetative morphology: Thalli were erect, delicate, intense pink-reddish to red-brownish, compressed and 1.5–5.5 cm high ( Fig. 2A–B View FIGURE 2 ), attached to the substratum by a small discoid holdfast ( Fig. 2C View FIGURE 2 ). Presence of few anastomoses between branches ( Fig. 2D View FIGURE 2 ), which were up to 2 mm wide, intensely and alternately branched ( Fig. 2E View FIGURE 2 ). Ultimate branchlets were terete and tapered to the ends ( Fig. 2E View FIGURE 2 ). Thallus organization was uniaxial, with an apical cell clearly visible ( Fig. 2F View FIGURE 2 ). In surface view, cortical cells were usually polygonal, with small outer cortical cells rounded to elongated, forming weakly developed rosettes ( Fig. 2G View FIGURE 2 ). In longitudinal section, an axial filament was surrounded by two layers of large medullary cells, linked by secondary pit-connections ( Fig. 2H View FIGURE 2 ). In cross section, middle portions of the thalli were 320–350 μm thick, with four to six layers of large, unpigmented, compressed, medullary cells ( Fig. 2I View FIGURE 2 ). The cortex was composed of 1–2 layers of pigmented, irregular cortical cells ( Fig. 2J View FIGURE 2 ). Lenticular thickenings were abundant in the cortical and medullary cells ( Figs 2I–J View FIGURE 2 ). Unicellular hairs were not observed.
Reproductive morphology: Spermatangia scattered in irregular patches over the young branches ( Fig. 3A View FIGURE 3 ). Mature spermatia were in chains, cut off from elongated spermatangial primordial cells ( Fig. 3B View FIGURE 3 ). Cystocarps were globose, sessile, and were formed at the edge of ultimate branchlets ( Fig. 3C View FIGURE 3 ). The auxiliary cell cuts off a gonimoblast initial inwardly ( Fig. 3D View FIGURE 3 ). Branched gonimoblast filaments, produced from the gonimoblast initial, develop towards the surface, while others grow inwardly and fuse with the basal inner nutritive cells, by secondary pit connections.As result of this fusion, a group of large cells, like columns, was formed in the center of carposporophyte ( Fig. 3E View FIGURE 3 ). No evidence of a fusion cell formation. Some transverse sterile filaments joined with the pericarp ( Fig. 3F View FIGURE 3 ). Gonimoblast filaments that developed outwardly produced terminal chains of ovoid carposporangia, 15–20 μm in diameter ( Fig. 3G View FIGURE 3 ). Mature cystocarps were 600–1000 μm wide and nonostiolate ( Fig. 3H View FIGURE 3 ). Tetrasporangia were scattered on proliferations ( Fig. 3I View FIGURE 3 ). Tetrasporangia were zonately divided, 40–45 μm long and 22.5–27.5 μm wide ( Fig. 3J–K View FIGURE 3 ).
Habitat and distribution: Calliblepharis jolyi was collected at Itaoca Beach (type locality) and other locations along the Espírito Santo coast, as part of the drift (as in the original description), epiphytic of Cryptonemia seminervis (C. Agardh) J. Agardh or forming tufts with Jania subulata (J. Ellis & Solander) Sonder. Calliblepharis jolyi can be easily distinguished by its habit resembling juvenile plants of Gracilaria cervicornis (Turner) J. Agardh. We could not find this species during our intertidal surveys, suggesting that its habitat is restricted to the subtidal. At present, C. jolyi is an endemic species from Brazil.
