Acicularia sp. 1

Fig. 4 a-i, l-o

Remarks: The longitudinal sections of the relative largesized spicules (length up to 2.0 mm) are straightrectangular (thickness ~ 0.3 mm), sometimes with a small central hollow and with close-set elongated cysts (width 0.08-0.15) of palisade-like appearance. This morphotype is the most common observed in the studied samples. It is typically associated with Jodotella veslensis Morellet & Morellet, Neomeris plagnensis Deloffre and Halimeda? sp.
