SUMMARY An ultrastructural study of motile cell development in the green alga Trentepohlia aurea has revealed the presence of multilayered structures (MLS) associated With flagellar bases. These MLS are ultrastructurally similar to MLS described in pteridophyte and bryophyte sperm and in the zoospore of the green algae Coleochaete and Klebsormidium. However, 2 MLS are found in each biflagellate motile cell of T. aurea , while other previously described MLS occur singly in biflagellate motile cells. In addition, the MLS of T. aurea consist of fewer microtubules and are structurally simpler than most other MLS described. The MLS of Trentepohlia may represent a stage in the evolutionary development of the MLS of land plants. The presence or absence of the MLS in motile cells of green algae may be a useful character in phylogenetic studies.
