The transfer of Gelidiella trinitatensis W.R. Taylor (Gelidiales, Rhodophyta) to Parviphycus

Evidence is presented to support the transfer of the red algal species Gelidiella trinitatensis W. R. Taylor (Gelidiales) to the segregate genus Parviphycus Santel. The very small stature of this alga, the arrangement of tetrasporangia in distinct chevron rows, the organization as seen in transverse section, and the apical organization indicate its correct taxonomic placement is within the genus Parviphycus . This species, originally described from Trinidad in the southern Caribbean Sea, is now known to be widely occurring throughout the Caribbean. It has also been reported from Central and South America (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
