Pseudomonas tolaasii is a Gram-negative soil bacteria that is the causal agent of bacterial blotch on cultivated mushrooms (Agaricus bisporus)[1]. It is known to produce a toxin, called tolaasin, which is responsible for the brown blotches associated with the disease[2]. It also demonstrates hemolytic activity, causing lysis of erythrocytes[3]. Based on 16S rRNA analysis, P. tolaasii has been placed in the P. fluorescens group[4].
