This survey presents studies about benthics marine chlorophyceae found in the Serrambi Beach, South coast of Pernambuco. The material studied was collected in three stations, which were visited monthly during the period from April, 1986 to September, 1987. The chlorophyceae were represented in this flora by 39 species, three varieties and one form, from orders Ulotrichales, Ulvales, Siphonocladales, Cladophorales, Caulerpales and Dasycladales. Acetabularia calyculus Quoy & Gaimard. In Freycinet, Bryopsis pennata Lamouroux, Bryopsis plumosa (Hudson) C. Agardh, Caulerpa ambigua Okamura, Caulerpa serrulata (Forsskål) J. Agardh emend Børgesen, Chaetomorpha brachygona Harvey, Cladophora coelothrix Kützing, Cladophoropsis membranacea (C. Agardh) Børgesen, Codium intertextum Collins & Hervey, Ernodesmis verticillata (Kützing) Børgesen are refered by first time from Pernambuco coast. Pringsheimiella scutata (Reinke) von Höhnel ex Marchewianka is for the continental Brazilian coast too. Halimeda opuntia (L.) Lamouroux was the host with the major number of epiphytes, while Bryopsis plumosa, when epiphyte, was the one that grew over the great number of hosts.
