Abstract. The type material of Cylindroporella sugdeni Elliott, 1957, is revised. The total lack of sterile laterals and consequently the absence of the diagnostic feature of the genus Cylindroporella, i.e., the alternation of sterile and fertile laterals within the same whorl, leads to its exclusion from the genus Cylindroporella Johnson, 1954, and to its ascription to the genus Holosporella Pia, 1930. Recent stratigraphic investigations suggest that the stratum typicum originally reported as Early Cretaceous in age is more precisely Hauterivian or possibly Early Barremian in age.

Short summary
Cylindroporella sugdeni Elliott, 1957, a fossil green calcareous alga originally found in lower Cretaceous strata of Oman, is revised. The species is transferred from the genus Cylindroporella Johnson, 1954, the thallus of which bears both fertile and sterile laterals, to the genus Holosporella Pia, 1930, the thallus of which bears only fertile laterals.
