Formatted Abstract/Summary Cylindrospermopsin and its deoxy analogue have been detected in a number of cyanobacteria throughout the world. Previously in Australia these toxins have been reported in Cylindrospermopsis raciborskii and Aphanizomenon ovalisporum. In both these species the deoxycylindrospermopsin levels are less than 10 % of the predominant toxin, cylindrospermopsin. Lyngbya wollei specimens from several streams in South East Queensland were found to contain deoxycylindrospermopsin as the predominant toxin with only low levels of cylindrospermopsin. The level of toxin in the water was below the detection level of 0.2 micrograms per Litre in contrast to the other two species mentioned which often give toxin levels in the surrounding water at similar concentrations to the toxin content of the cells. This is the first report of these toxins being detected in a benthic cyanobacterial species.
