Abstract
New observations on abundant material from the type locality of Petrascula iberica (Dragastan et Trappe), Granier et al. 2003, reveal the presence of a reproductive structure (ampulla) located on the inner-middle part of each primary lateral. This fact suggests a new interpretation of the alga and the establishment of a new genus: Granieria Barattolo et Romano, n. gen. Also, the taxonomic status of the other club-shaped specimens from both the High and Middle Atlas and the Central Apennines of Italy is reviewed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
