Abstract

The speciemns of red algae “Gracilaria corticata” were collected from the rocky intertidal
shores in Bostaneh Port in the Persian Gulf and Lipar in Oman Sea in May, June and August
2013. Anatomical, morphological structures, thallus of vegetative and reproductive samples
were studied. Carpogonial and tetrasporangium stages were determined based on histological
and morphological methods. The female thallus, the Cystocarp with hemispherical structure
through out thallus were observed. The Spermatangial conceptacle was located deeper as the
oval shape in male thallus. The tetrasporophytic stage of diploid samples was determined by
the presence of tetrasporangium oval shape.
