Ectocarpus
Ectocarpus siliculosus
Ectocarpus is a genus of brown algae from the order of Ectocarpales.
Features
Ectocarpus species are yellowish brown, olive-brown or dark brown in color. The thalli consist of tufts of finely branched filaments of single row butted cells. The limp and slimy threads flooding long in the water or form loose Watten. With a holdfast of low -lying, densely branched Basalfäden they grow tightly ( benthic ) on rocks and stones or even on larger algae ( epiphytic ). The genus is extremely variable in shape.
Ectocarpus shows a mostly isomorphic or slightly heteromorphic alternation of generations, but it also occur asexual forms.
Occurrence
Ectocarpus is widespread and possibly occurs almost worldwide, but is absent in the Antarctic. The species grow from the intertidal to subtidal.
System
The genus Ectocarpus was erected in 1819 by Hans Christian Lyngbye ( in: Tentamen hydrophytologiae danicae ). The type species is Ectocarpus siliculosus ( Dillwyn ) Lyngbye.
