AGUILAR-ROSAS, Luis E.  e  AGUILAR-ROSAS, Raúl. The genus Porphyra (Bangiaceae, Rhodophyta) in the Pacific coast of Mexico. II. Porphyra thuretii Setchell et Dawson. Hidrobiológica [online]. 2003, vol.13, n.2, pp.159-164. ISSN 0188-8897.

Occurrence and seasonality of Porphyra thuretii Setchell et Dawson (Bangiaceae, Rhodophyta) is recorded for the Pacific coast of Mexico, based on sampling conducted in 1997, 2001 and 2002, and those deposited in national and foreign herbaria. P. thuretii is reported for first time for the coast of Sinaloa, México. We describe details of morfpho-anatomic characters and reproductive structures of the thallus, as well as its habitat and geographic distribution.
