Abstract
A new marine microfilamentous green alga, Chaetomorpha philippinensis Leliaert sp. nov., is described as an epiphyte on Chaetomorpha vieillardii from shallow subtidal habitats in the Philippines. Phylogenetic analyses of large subunit rDNA and rDNA internal transcribed spacer (ITS) sequences show that the new tropical species is sister to the cold-water Chaetomorpha norvegica, from which it is genetically clearly distinct but morphologically almost indistinguishable. Chaetomorpha philippinensis is characterized by minute, straight or curved, unbranched, erect filaments up to 300 mu m long and 7-17 mu m in diameter, attached by a basal, hapteroid holdfast. Filaments in culture are similar in morphology but grow considerably longer with slightly larger cells. The cylindrical cells are multinucleate with up to eight nuclei (up to 18 in culture). Cells contain a single, parietal, lobed chloroplast with numerous small perforations and one to several pyrenoids. Zoosporangia develop by transformation of apical and subapical cells with zoids emerging through a domed pore in the apical, middle or basal part of the cell.
