Dinophysis acuta Ehrenberg
The characteristics of this genus such as the high girdle with lists giving the form of a collar, the flattened cell with the sulcus running down the right hand edge of the picture, also with a list giving the form of a sail, make it relatively easy to id. © Robin Raine (Robin.Raine@nuigalway.ie).
