Effect of the fungal pathogen Verticillium fungicola on fruiting initiation of its host, Agaricus bisporus

Abstract

Dry bubble disease caused by the fungal pathogen Verticillium fungicola1 is responsible for large losses to the mushroom (Agaricus bisporus) industry. The pathogen induces various symptoms on the host, bubbles (undifferentiated spherical masses), bent and/or split stipes (blowout) and spotty caps. Inoculation of A. bisporus crops with isolates of V. fungicola var. fungicola of various degrees of aggressiveness showed that the more aggressive isolates induced higher numbers of bubbles. The production of other symptoms did not vary with the isolate of pathogen. The total weight of the crop (healthy and diseased mushrooms) was not significantly affected by the disease, but inoculation with highly aggressive isolates resulted in a significant increase in the total numbers of mushrooms. Two hypotheses are proposed to explain the effect of the pathogen on fruiting initiation in relation to aggressiveness.
