Abstract
Ultrathin sections of two rotifer-capturing species of Cephaliophora, C. muscicola and C. longispora , were compared with those of Zoophagus insidians . Accumulation of electron-dense vehicles in the adhesive pegs, and mitochondria with lamellar cristae, are common to all three species. The outer layer of the apical portion of the adhesive peg in Z. insidians has distinctive ridge-like markings. In the Cephaliophora species, the cell wall at the apex of the peg is somewhat irregular in outline but lacks ridge-like markings. In Z. insidians , the living, vegetative hyphae are nonseptate. Adventitious septa are formed in senescing hyphae to delimit the living portion from the dead, evacuated portion. In the two species of Cephaliophora , septa occur regularly and frequently in hyphae and conidia. Such septa have a central pore which is similar in its ultrastructural detail to those reported for the Ascomycota/Deuteromycota. Anastomoses are common in all isolates of the rotifer-trapping Cephaliophora species examined. Anastomoses were not observed in the isolates of Z. insidians . We conclude that C. musciola and C. longispora are properly placed in the Hyphomycetes.
