Gastroclonium reflexum is a small red alga (Rhodophyta) reported from Ireland and Britain.
This small alga grows to about 6 cm long: the fronds grow from a branched holdfast are reflexed and form haptera where they meet the rock. The branches are hollow, terete to 6 cm long and constricted by septa giving a beaded appearance. The secondary branching is dichotomous, distichous. In colour they are dark purplish red. [1] The species is very similar to Chylocladia verticillata with which it may be confused. [2] Spermatangia, cystocarps and polysporangia have been recorded. [1]
