摘要: The life history of the red alga Rhodophysema elegans (J. Ag.) Dixon (Peyssoneliaceae: Cryptonemiales), which was commonly found at 4 localities on south coast England, has been investigated in laboratory culture. Tetraspores (the only reproductive organs observed) were derived from field material germinated to repeat parental tetrasporangiate phase. Sexual not observed. It is suggested that probable cause this “direct” type occurrence apomeiosis sporangial primordium.
