Common names

(as Cordylecladia erecta (Greville) J.Agardh)
English: Erect Clublet (Bunker & al. 2010).

Description
Narrow cylindrical, cartilaginous, brownish-red fronds, to 100 mm high, in tufts from thin, spreading, discoid base often hidden below sand. Sparingly subdichotomously branched, branches usually tapering to fine point. Dioecious. Tetrasporangia and spermatangia in terminal, deciduous, spindle-shaped pods, cystocarps clustered in swollen areas near apices. Reproduction takes place in the depths of winter.

Habitat
On sand-covered rocks, low intertidal and subtidal, widely distributed, frequently overlooked.

Similar species
Frequently confused with Gracilaria longissima and Gracilaria gracilis both of which do not have an expanded crustose base. Cordylecladia erecta is smaller, generally stands erect and has a brownish-red rather than a purplish-red colour. Plants of Gracilaria longissima may have irregularly sollen areas when growing in sand or shell-sand. Reproductive plants of C. erecta are only found in winter when the reproductive structures occur in swollen, often spindle-shaped areas near the tips of the fronds.
