Description

2. Cladophora catenata (L.) Kütz. emend. Hoek (1963). Map 1; Figs. 1C–E

Conferva catenata Linnaeus (1753:1166).

Thalli dark green to black, forming stiff cushions, (2 –) 2.5 (– 3) cm high, attached to the substrate by basal and/or hapteroid rhizoids that sprouted on the tips of apical cells. Unilateral ramification, with laterally inserted branches cut off by a transverse wall. Apical cells long and rounded or tapered gradually to the tip. Apical cells (195 –) 229 (– 274) µm wide and (1236 –) 2492 (– 3892) µm long, with L/W ratio of (6 –) 11 (– 17). Lateral branch cells (188 –) 218.5 (– 256) µm wide and (762 –) 988 (– 1221) µm long, with L/W ratio of (3 –) 4.5 – (6). Main axis cells usually curved and almost prostrate, measuring (199 –) 241.5 (– 292) µm wide and (758 –) 1073 (– 1496) µm long, with L/W ratio of (3 –) 4.5 (– 6). The fungus Blodgettia bornetii E.P. Wright (1881:25) was always present along cell walls of thalli.

Curaçao: St. Joris-binnenbaai, 11 Mar. 1958, Vroman (L 0441625); San Pedro, 07 Jun. 1968, Hoek (L 0441597); PORTO RICO.

Comments: Specimens were collected growing in the midlittoral zone on plateaus of the sandstone reef from Pernambuco and Bahia. These specimens were accompanied by Anadyomene stellata (Wulfen) Agardh (1823: 400), Dictyosphaeria cavernosa (Forsskål) BΦrgesen (1932: 2), Phyllodictyon anastomosans (Harvey) Kraft & Wynne (1996: 139), Hydroclathrus clathratus (Agardh) Howe (1920: 590), Dictyopteris delicatula Lamouroux (1809: 332), Dictyota mertensii (Martius) Kützing (1859: 15), D. pulchella Hörnig & Schnetter (1988: 287), Padina gymnospora (Kützing) Sonder (1871: 47), Sphacelaria tribuloides Meneghini (1840: 2), Jania adhaerens Lamouroux (1816: 270), Hypnea musciformis (Wulfen) Lamouroux (1813: 43), Bryothamnion seaforthii (Turner) Kützing (1843a: 433), Digenea simplex (Wulfen) Agardh (1822: 389), Palisada perforata (Bory de Saint-Vincent) Nam (2007: 54) and Osmundaria obtusiloba (Agardh) Norris (1991: 14). The specimens also grew as epiphytes on Laurencia dendroidea Agardh (1852: 753) and Palisada perforata. In addition, we observed C. catenata as a host to A. stellata, Pneophyllum fragile Kützing (1843b: 385), Ceramium vagans P.C.Silva in Silva et al. (1987: 56), diatoms and cyanobacteria.

The representatives of C. catenata from Pernambuco showed a slightly higher cell width than those from Bahia. There are records of this species along the Brazilian coast in the following areas: Ceará (Oliveira-Filho 1977), Rio Grande do Norte (as C. fuliginosa Kützing (1849: 415) by Pereira et al. 1980), Pernambuco (Pereira et al. 2002) and Rio de Janeiro (Gestinari et al. 1998). However, the collected representatives from Reserva Biológica Estadual da Praia do Sul na Ilha Grande, Rio de Janeiro (Gestinari et al. 1998) are actually the species C. corallicola. No herbarium specimens of C. catenata were from the Pernambuco littoral zone, although Pereira et al. (2002) had recorded its occurrence. The studied specimens matched descriptions of species from the North Atlantic (Taylor 1960; Hoek 1982), the Mediterranean (Hoek 1963), Japan and eastern Russia (Hoek & Chihara 2000). We observed the characteristic presence of fungi in the cell walls (Hoek 1963, 1982; Hoek & Chihara 2000). The species C. catenata was thought to be restricted to the tropical shores of the Atlantic and Pacific Oceans, its northernmost boundary being the shores of Japan in the Pacific Ocean (Hoek 1969, Hoek & Chihara 2000), but recently Leliaert & Coppejans (2003) collected this species from the South-Western Indian Ocean (South Africa). Our study provides the first record from Bahia.
