Steinmanniporella, a new dasycladale genus name for “Linoporella” with two orders of laterals

International audienceAfter Barattolo (Abstracts of the 5th international symposium on fossil algae, 1991) and Barattolo and Romano (Bollettino della Societa Paleontologica Italiana, 44(3): 237–254, 2005) emended the diagnosis of the genus Linoporella Steinmann to include species with three orders of laterals, algae included formerly in this genus but with only two orders of laterals remained in open nomenclature. Comparisons of these algae with other Jurassic and Cretaceous dasycladaleans with two orders of laterals resulted in the introduction of the new genus Steinmanniporella
