Description[edit]
Gastroclonium ovatum is a small alga which grows to 15 cm long. The branches are cylindrical, grow from a branched holdfast and branch irregularly. It shows short branches which are hollow with bladder-like or vesicle-like branches - rather elongate with a single joint. In colour it is dark purplish red.[1][2][3]
Habitat[edit]
Found in rock pools in the littoral or upper sublittoral, epilithic or epiphytic.[2]
Distribution[edit]
Recorded from the British Isles, Mauritania, Canary Islands[2] and the Channel Islands.[1]
Reproduction[edit]
The sexes are separate. The female cystocarps occur on the branches and the tetrasporangia in the cortex of the vesicles.[1]
Similar species[edit]
Gastroclonium reflexum distinguished by many branches being reflexed[2] and Chylocladia verticillata.[1]
