WebNot all strains within Phormidium-dominated mats produce anatoxins and some mats therefore contain no toxins (Wood et al. 2010a, 2011, 2012a). A recent collation and review of toxin data from Phormidium -dominated mats in New Zealand found that 67% of samples ( n = 771) from 40 rivers contained anatoxins (McAllister et al. 2016 ).
