Resumen

AGUILAR-ROSAS, Raúl; AGUILAR-ROSAS, Luis E.  y  PEDROCHE, Francisco F.. Description of spermatangial thalli and mixed-phase in Polysiphonia confusa (Rhodomelaceae, Rhodophycota). Rev. Mex. Biodiv. [online]. 2006, vol.77, n.1, pp. 1-6. ISSN 2007-8706.

The spermatangial phase and the mixed phases (tetrasporangia and cystocarps) on the same thallus in Polysiphonia confusa Hollenberg (Rhodomelaceae, Rhodophycota) are described for the first time. Spermatangial thalli are important to characterize and compare this species with others from the genus Polysiphonia. Habit, vegetative and reproductive development have been examined in plants of this species from the intertidal zone of Saldamando Beach, Baja California, México. Because of its small size, this species has been overlooked in the Mexican Pacific coast resulting in a small numbre of records for this taxon.

Palabras llave : Baja California; México; red algae; reproductive phases; Ceramiales.
