What is it; Microseira wollei (M. wollei) is a prokaryotic cyanobacterium that can produce taste and odor compounds and toxins and can subsequently impede critical water resource uses (e.g., recreation) and lower property values. (Page 9 Line 1)

Where does it come from; Originates from toxins, disinfection by-products, and, potentially, fecal indicator bacteria. ( Page 2 Line 13)

Is it dangerous; M. wollei can pose risks to human health through the production of compounds (i.e., DBP precursors and toxins) and potentially by harboring FIB (Page 28 Line 1)

Does it affect native plants; M. wollei significantly decreased the germination of three of the five plants evaluated. Observations of M. wollei growths smothering native vegetation have been anecdotally reported (Joyner 2007). M. wollei may harm plants by physically covering vegetation and by chemical means
