Incidence of brown‐discoloured mushrooms, differing from brown blotch disease caused by Pseudomonas tolaasii , has increased in the Netherlands and been responsible for considerable economic losses. A comparative SEM‐study of diseased tissue revealed that hyphae were collapsed and covered with a plaque in which numerous bacteria were embedded. The predominant bacterium identified was Pseudomonas agarici. Both our isolated P. agarici strain and the type strain P. agarici LMG 2112 caused brown discolouration of mushrooms after spraying with bacterial suspensions. Drippy‐gill symptoms were not observed.
