摘要
A culture of a synnematous hyphomycete belonging to Phaeoisaria was isolated from surface sediment on the coast of Weihai, China. It is described as a new species, Phaeoisaria sedimenticola, based on morphological characters and nuclear ribosomal DNA sequences (large subunit and internal transcribed spacer regions). Phaeoisaria sedimenticola is distinguished by its indeterminate synnemata, more or less cylindrical conidiogenous cells, hyaline obovoid to ellipsoidal conidia with pointed bases, aseptate conidia (3.6-7.5 x 2.5-4.4 mu m), and 1-septate conidia (4.5-9 x 2-4.5 mu m) that are slightly constricted at the septum.
