Maintenance of Didymosphaenia M. Schmidt as a distinct diatom genus is supported by an examination of D. sibirica (Grun.) M. Schm. with the scanning electron microscope. This investigation of D. sibirica reveals features similar to those of D. geminata (Lyngb.) M. Schm. and substantiates the existence of the genus separate from Gomphonema. D. sibirica is, however, a quite distinct species. 相似文献
