Heterocapsa triquetra (Ehrenberg) Stein, 1883
Heterocapsa triquetra
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
