Abstract

Heterotallic sexual reproduction was obtained and described in an unknown Atlantic species Haslea sp., which differs by extremely big cells (54–232 μm) from all other representatives of the genus having characteristic blue color. Two spherical gametes formed in each of the parent cells. The species is characterized by the isogamous type of sexual reproduction (complete isogamy, morphological and behavioral). According to the system developed by Geitler, the type of sexual process corresponds to category IB2a.
