BORASO DE ZAIXSO, Alicia L.  e  AKSELMAN, Rut. Anotrichium furcellatum (Ceramiaceae, Rhodophyta) in Argentina: A possible invasive species. Bol. Soc. Argent. Bot. [online]. 2005, vol.40, n.3-4, pp.207-213. ISSN 1851-2372.

At least two populations of Anotrichium are reported from the coast of Argentina (Buenos Aires, Chubut, and Santa Cruz provinces). These populations have a majority of vegetative thalli. According with their morphological and tetrasporangial characteristics the populations are provisionally assigned to Anotrichium furcellatum (J. Agardh) Baldock. The characteristics of the thalli of studied populations are compared with the species of Anotrichium having also a low number of tetrasporangia per cell. Extraordinary high quantities of cast ashore thalli of this species is reported along the Buenos Aires province coast in the year 2000.
