(Microcystis spp)

Often referred to as a slick or film, microcystis is a colonial variety of cyanobacteria.  Buoyant cells accumulate along shores in windward direction. Microcystis is commonly found in nutrient-rich ponds in mid to late summer. Contact with microcystis blooms may cause skin irritation and gastrointestinal distress. Avoiding contact is advisable.
