A dry bubble is an undifferentiated structure that forms in place of mushrooms when cultures of Agaricus bisporus are contaminated by Verticillium fungicola . Hydrogen peroxide concentrations were measured in lyophilised samples of bubbles and healthy sporocarps from cultures of genetically related strains of A. bisporus . The strains the more resistant to the pathogen had the higher levels of H 2 O 2 concentration measured in the bubbles, but the differences in the healthy sporocarps were not significant. That is an indication of a higher reaction to the pathogen in the forming sporocarps of A. bisporus strains associated with their partial resistance to V. fungicola .
