A bacterial disease occurred on fruiting bodies of Lentinula edodesthat formed outdoors on Quercusbedlogs during winter. The pathogen was identified as Pseudomonas tolaasiibased on morphological and bacteriological characteristics. Symptoms exhibited by infected fruiting bodies ranged from mild browning to severe necrotic cavities that characteristically developed in the cap tissue along the periphery of the attachment area to the stalk. The mode of symptom development was greatly influenced by the internal tissue structure of fruiting bodies. Multiplication of bacterial cells within the fruiting bodies was strictly intercellular and thus differed from previously reported bacterial disease of L. edodesincited by an unidentified rod-shaped bacterium. The present strain of P. tolaasiiwas capable of attacking the L. edodesmycelium in the inner bark and outer sapwood regions and caused lysis of heavily infected hyphae. |
