An addendum to Schneider and Wynne's A synoptic review of the classification of red algal genera a half century after Kylin's “Die Gattungen der Rhodophyceen” (2007; Bot. Mar. 50: 197–249) is presented, with an updating of names of new taxa at the generic level and higher. In the last few years, the names of several new orders and families of red algae have been validated; these are cited and referenced below.

A synthesis of the benthic marine algal flora for the Texas coastline is compiled. A total of 208 taxa of benthic macroalgae is presented, including 114 taxa of Rhodophyceae (red algae), 28 taxa of Phaeophyceae (brown algae), and 66 taxa of Ulvophyceae (green algae). These algal taxa are placed in an arrangement according to the most currently accepted schemes of classification, reflecting the results of comparative phylogenetic treatments. Explanatory "Notes" with information on taxonomic and nomenclatural changes are included.
