The table below contains some images of algae that were collected and preserved in Lugol's solution. The sample was taken at the marina as a grab sample in June 2009. No shoreline algae were included in the sample. The dominant form in the sample is Cryptomonas, a cryptomonad, and the subdominant forms include the diatoms Fragillaria, Melosira, Synedra, and Navicula.
Other algae include the chrysophyte, Synura, some green algae that include Scenedesmus, Actinastrum, and Pandorina.
Several blue green algae include Anabaena, Microcystis, and Oscillatoria.
|Actinastrum, a green alga and the star like colony aside the filament of Melosira, a diatom taken at 400x||Anabaena, a blue green filament and adjacent to that is Cryptomonas, a cryptomonadtaken at 400x||Cryptomonas, the dominant alga in the June 2009 sample from Lake Fayetteville taken at 400X||Multiple cells of Cryptomonas taken at 100x. This was the organism that caused a bloom and turned the water a brownish hue.|
|Fragillaria, a filamentous diatom and an associated Cryptomonas taken at 400X||Frustulia, a very large diatom taken at 400X||Microcystis, a colonial blue green alga taken at 400x||Oscillatoria a filamentous blue green alga taken at 400x|
The following table contains images from a grab sample taken at the dock in June 2010.
