description
Representative specimens examined: — BRAZIL. Bahia: Ilha de Itaparica, Vera Cruz, Praia da Penha, 18 / III / 2007, Moura (HUEFS 130885); 14 / VII / 2007, Alves & Peixoto (HUEFS 130887). Praia da Barra Grande, 19 / III / 2007, Santos (HUEFS 147560); 18 / V / 2007, Santos (HUEFS 147561); 14 / VII / 2007, Santos (HUEFS 147562); 27 / IX / 2007, Oliveira & Oliveira (HUEFS 130890). Geographic distribution along the west coast of Atlantic Ocean: — Florida, Bahamas, Belize, Cuba, Venezuela, Brazil (Taylor 1960, Ganesan 1989, Littler et al. 1995, Littler & Littler 2000, Bacci 2005, Suárez 2005, Ribeiro 2008). Comments: — Chondria collinsiana is restricted to the Caribbean Sea, the South Atlantic, and the Indian Ocean (Jaasund 1976, Littler et al. 1995, Bacci 2005, Ribeiro 2008). Along the Brazilian coast this species was previously known only from the states of Espírito Santo (Bacci 2005) and Rio de Janeiro (Ribeiro 2008). The present study expanded the distribution of this species to the northeastern coast of Brazil. The specimens analyzed are in agreement with the characteristics described and illustrated by Littler et al. (1995) and Bacci (2005). According to Bacci (2005), this species differs from the others along the coast of the states of Espírito Santo and São Paulo by having an erect thallus, delicate, densely radially branched, slight depressions at the apices of the branches and branchlets, and by the presence of lenticular thickenings on the medullar cell walls. In addition to these morphological characteristics, the shapes of the sterile cells of the spermatangial bodies and the characteristics of the cistocarp are useful in identifying species of C hondria C. Agardh (Bacci 2005). This is the first report of masculine gametophytes of this species from the Brazilian coast. They were described earlier by Littler et al. (1995) for the flora of Belize. The spermatangial bodies of Chondria collinsiana are laminar, discoidal, with rounded spermacia, surrounded by a layer of rectangular sterile cells, as can be seen in Fig. 1 I. Thalli were observed growing isolated on the thallus of A. crenulata, sometimes forming dense tufts when attachments are present in the basal region of the thallus.
