Description
The thallus grows to 35 cm long - smaller than other similar species, it is attached by a discoid holdfast. The thallus is flattened and has a midrib like the other common species of '' Fucus''. However it does not have bladders, as '' Fucus vesiculosus'', or serrated edges to the fronds as '' Fucus serratus'' nor a twisted thallus, as '' Fucus spiralis''. '' Fucus ceranoides'' does not have bladders but may have elongated air pockets in the fronds. The receptacles on ''F. guiryi'' show a distinct rim around the edge.[Bunker, F.StP,D, Maggs, C.A., Brodie, J.A., Bunker, A.R. 2017. ''Seaweeds of Britain and Ireland''. Second Edition.
