Mucilaginous layer on Spirogyra
The objective for this image was to show the mucilaginous layer which covers the filament. It is evident at the center in the septum bridging the gap between the two cell end walls. It appears as a halo. This is what makes the material feel slimy.
Specimen of Spyrogyra collected from a spring near the Pucker Street Dam on the Dowagiac River 2/7/2015.
Imaging was performed with a Spencer 43 petrographic microscope with a Spencer dark field condenser oiled to the slide with a Spencer 10X objective and a Leica MIKAS camera adapter with 10X eyepiece and 1/3X reducer. Original magnification 33X on the Sony NEX 5N sensor.
