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. Carposporophyte produces mitospores called carpospores.
