Abstract

A bacterial disease occurred on fruiting bodies ofLentinula edodes that formed outdoors onQuercus bedlogs during winter. The pathogen was identified asPseudomonas tolaasii based 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 ofL. edodes incited by an unidentified rod-shaped bacterium. The present strain ofP. tolaasii was capable of attacking theL. edodes mycelium in the inner bark and outer sapwood regions and caused lysis of heavily infected hyphae.
