AB The morphology of the western Atlantic Botryocladia shanksii E. Y. Dawsonand B. pyriformis (Børgesen) Kylin are examined in material collected in the CanaryIslands, confirming the amphi-Atlantic distribution of both species. Botryocladia shanksii,which was found growing in the lower eulittoral, is reported for the first time in the eastern Atlantic, and the origin and disposition of tetrasporangia is documented. Tetrasporangiaare derived from inner intercalary cortical cells and are scattered throughout the cortex inthe subsurface cortical layer. The occurrence of B. pyriformis in the eastern Atlantic is confirmed by an examination of deep-water plants from the Canaries that are in agreementwith the original description of Chrysymenia pyriformis Børgesen. Cystocarp structure isdescribed in detail for the first time. Cystocarps are largely immersed in the vesicle withcompact lobed gonimoblasts composed entirely of angular carposporangia. The distributionof Botryocladia species in the Atlantic Ocean is given.
