Neogyroporella? gawlicki n.sp., a New Dasycladale from the Upper Jurassic–Lower Cretaceous “Lärchberg Formation” of the Northern Calcareous Alps, Austria

A new Dasycladale (calcareous green alga) is described as Neogyroporella? gawlicki n.sp. from the Upper Jurassic–Lower Cretaceous “Larchberg Formation” of the Northern Calcareous Alps, Austria. It is distinguished from the type-species Neogyroporella elegans YABE & TOYAMA (Upper Jurassic of Japan; currently the only representative of the genus), by its distinctly smaller dimensions and a higher number of laterals. The generic attribution of the new taxon is discussed, including similarities/differences to allied genera, especially Humiella SOKAC & VELIC. Neogyroporella? gawlicki n.sp. is so far only known from the Northern Calcareous Alps. In addition, some other Dasycladales accompanying Neogyroporella? gawlicki n.sp. are also illustrated.
