Dinophysis acuminata Claparède & Lachmann
Dinophysis acuminata
light microscopy (LM); epifluorescence microscopy (WU) - blue excitation light obtained with a combination of BP330-385 excitation filter, DM400 dichroic mirror and BA420 barrier filter; this combination with Calco Fluor White M2R fluorescent brighter elicited a blue fluorescence of cellulose theca, a green fluorescence of the cytoplasm (carotenoids probably), an orange fluorescence of phycoerithrin and phycocyanin (probably cyanobacterial or cryptophycean endosymbionts).
