Gametangia of both mating types release isomorphic gametes. Alga is isogamous. The life cycle is sporic. This red algal organism consists of a filamentous thallus. The thalli in the wild are isomorphic.
Gametophytes are heterothallic and isomorphic.
Male gametophytes release spermatia from a spermatangium. Female gametophytes produce a carpogonium with a trichogyne. Spermatia unite with the trichogyne, an auxiliary cell becomes the zygote. Alga is oogamous. Zygote grows into a carposporophyte attached to female gametophyte.
