Conferva vagabunda Linnaeus (1753: 1167)

Thalli feeble to slightly stiff, forming pompom-like tufts, grass green or pale green, (4 –) 7 (– 13) cm high (sometimes reaching up to 25 cm high), attached to the substrate by a basal disc formed by branching rhizoids sprouting from basal and sub-basal cells. Branching dichotomous in basal part of thallus to unilateral at distal parts, with acropetally organized branch system, straight, fasciculate or falcate. Apical cells cylindrical with tapering tips, sometimes conical, measuring (52 –) 68 (– 90) µm wide and (151 –) 212 (– 288) µm long with L/ W ratio of (2.5 –) 3.5 (– 4.5); terminal branch cells (66 –) 83 (– 103,5) µm wide and (221 –) 286,5 (– 367) µm long with L/W ratio of (3 –) 4 (– 5); main axis cells (157 –) 189 (– 223) µm wide and (895 –) 1292 (– 1691) µm long with L/W ratio of (5 –) 7 (– 9). Fertile specimens were collected from Boa Viagem Beach (PE), Baleia, Capuba and Setiba Beachs (ES), Adão e Eva and Prainha Beachs (RJ), Farol Island and Morro do Meio Point (PR) and Ponta das Canas Beach (SC).

Comments: This is a very common species along the Brazilian coast, epilithic or epizoic, being found growing in boulders and rocky shores (SE, ES, RJ, PR, SC, RS), in close contact with the sand (RJ, PR), or partially covered by sand CE); specimens were also collected attached to sandstone reef plateaus (PB, PE, AL, BA), or growing in intertidal pools (CE, PE, AL). It grows with other algae, as an epiphyte on Cladophora prolifera , Halimeda opuntia (Linnaeus) Lamouroux (1816: 308) , Padina gymnospora , Gelidium pusillum , Chondracanthus acicularis , Cryptonemia seminervis , Grateloupia filicina (J.V.Lamouroux) Agardh (1822: 223) , Bryothamnion seaforthii , B triquetrum , Laurencia sp. Among the accompanying species, we most commonly found Ulva spp. , Chaetomorpha aerea , Cladophora corallicola , C. dalmatica , C. rupestris , Padina gymnospora , Grateloupia filicina , Hypnea musciformis , Centroceras sp. , Spyridia filamentosa (Wulfen) Harvey in Hooker (1833: 337), Bryocladia thyrsigera and Polysiphonia subtilissima . Cladophora vagabunda bears Ulvella sp. , Erythrotrichia carnea, Sahlingia subintegra, Pneophyllum fragille , H. musciformis , Ceramium spp. , as well many diatoms and cyanobacteria as epiphytes.

C. vagabunda is widespread along the Brazilian coast, being found from Maranhão to Rio Grande do Sul States (as C. fascicularis: (Mertens ex C.Agardh) Kützing (1843b: 268) Joly 1965, Baptista 1973, Santos 1983, as C. vagabunda: Oliveira-Filho 1977 ; Kanagawa 1984; Yoneshigue 1985; Martins et al. 1991; Pereira et al. 2002). A remarkable morphological plasticity was observed in the specimens studied, influenced by age and the environment ( Hoek 1982): plants from exposed sites showed very dense fasciculate branching (PB, PE, SE, BA, AL, RJ, SP, PR, SC, RS), while feeble thalli with less fasciculate branching were found in pools and sheltered sites (CE, PE), but the cell widths overall were quite consistent. C. vagabunda is a common cosmopolitan species which is widely distributed in the tropics and temperate zones of both hemispheres, and in the Atlantic, Pacific and Indian Oceans ( Hoek 1963, 1982; Lawson & John 1982; Hoek & Womersley 1984; Silva et al. 1996; Hoek & Chihara 2000, Brodie et al. 2007). According to Hoek & Chihara (2000), C. vagabunda would seem to occupy one large and continuous geographic area. However, molecular analyses based on DNA-DNA hybridization experiments ( Bot et al. 1990) and nuclear rDNA ITS sequences ( Bakker et al. 1995) have demonstrated that the morphologically plastic C. vagabunda represents at least four divergent lineages ( Hanyuda et al. 2002, Leliaert et al. 2003, 2007, Brodie et al. 2007, Leliaert et al. 2009). According to Gestinari et al. (2009), the inclusion of sequences from Brazilian individuals of Cladophora reinforces the need of taxonomical revision for the genus and for the complex C. vagabunda . To have a better understanding of the monophyly and of the divergence among species and isolates of the Cladophora vagabunda complex it will be necessary to obtain sequences for other molecular markers and from a broader geographic sampling. This is the first record of this species from Alagoas and Sergipe States.
