AGUILAR-ROSAS, Raúl; AGUILAR-ROSAS, Luis Ernesto  y  AVILA-SERRANO, Guillermo. NUEVOS REGISTROS DE STYLONEMA ALSIDII (ZANARDINI) DREW Y S. CORNU-CERVI REINSCH (PORPHYRIDIALES, RHODOPHYTA) PARA LA COSTA DEL PACÍFICO MEXICANO. Polibotánica [online]. 2006, n.22, pp.51-62. ISSN 1405-2768.

Stylonema cornu-cervi Reinsch (Porphyridiales, Rhodophyta) is reported for first time from the Mexican Pacific coast. Likewise, new localities are reported for Stylonema alsidii (Zanardini) Drew along the west coast of Baja California. Specimens were collected from the subtidal zone of Campo Kennedy, Rancho Packard and Pesquera Zapata in Todos Santos Bay, Baja California, during 1995-2001. The morphology, reproductive stage, habitat and geographic distribution in the study area are described for each species. The scarcity of records for Stylonema is probably related to the small size of these species and the lack of floristic studies of the subtidal zone in the study area.
