Origin of Species Name
Noun (singular possessive) (Latinised), in honour of Michael D. Guiry, Irish botanist.

General Environment
This is a marine species.

Description
Similar in morphology to Fucus vesiculosus L. but distinguished from it by hermaphroditic receptacles, the presence of a receptacle sterile rim, monopodial branching, and the absence of bladders; by shorter thallus and shorter frond length between the holdfast and the first dichotomy; by less wide apical frond; by higher and wider receptacles; by higher ratio of receptacle width:length and receptacle height:length; by higher intertidal zonation and physiological resilience to air exposure; by differences in the nuclear protein coding gene transcripts (BiP1, clpB, clpC, clpP, eIF3l, HSP90_1, HSP90_2, PXMP2/4_2, mpv17l2, TTC1, STI1, CCT4, CCT-epsilon, PXMP2/4_1) and microsatellite loci (L20, L78). Also similar in morphology to Fucus spiralis L. but distinguished from it by the presence of a receptacle sterile rim and monopodial branching; by longer thallus and frond between the holdfast and the first dichotomy; by wider apical frond; by shorter receptacle height; longer receptacle; wider receptacle; by smaller ratio of receptacle width:length and receptacle height: length; by lower intertidal zonation and physiological resilience to air exposure; by differences in the nuclear protein coding gene transcripts (BiP1, clpB, clpC, clpP, eIF3l, HSP90_1, HSP90_2, PXMP2/4_2, mpv17l2, TTC1, STI1, CCT4, CCT-epsilon, PXMP2/4_1) and microsatellite loci (L20, L78). [Original description.]

Key Characteristics
