shows a wide variability in outer shape. This is best shown in the study by Burton (1932) who illustrated one fragmentary specimen of blade-shape, which has a surface with numerous small oscules/pores and an underside of a quite irregular structure, thus somewhat resembling our new specimen. He also described specimens of irregular massive growth with some large oscules at the top. Koltun (1964) also reported specimens with “Body globular (with large oscules)”. Several (fragmentary) specimens are figured in Ríos (2006). These show intermediate growth, but with a tendency to form flattened structures without distinct oscules. Within the genus
