Dry bubble disease caused by the fungal pathogen Verticillium fungicola 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.
由真菌病原体黄萎病菌引起的干泡病给蘑菇（双孢蘑菇）产业造成了巨大损失。该病原体在寄主上引发各种症状，如气泡（未分化的球形团块）、弯曲和/或裂开的菌柄（爆裂）以及有斑点的菌盖。用不同致病力程度的黄萎病菌变种的分离株接种双孢蘑菇作物，结果表明致病力更强的分离株会诱导产生更多的气泡。其他症状的产生与病原体分离株无关。作物（健康和患病蘑菇）的总重量并未受到该病的显著影响，但接种致病力强的分离株会导致蘑菇总数显著增加。提出了两种假说，以解释病原体在致病力方面对出菇起始的影响。
