Three species of parasitic fungi fumigated for 12 hours at each of three ozone levels show these responses: (1) general growth inhibition was evident with each species showing individual differences with respect to the amount of growth suppression and the levels at which suppression was most apparent. (2) Microscopic responses included an increase in number and size of highly refractive, intercellular globules. The number and size of the globules differed with each species and with the concentration of ozone. (3) Spore production was both significantly reduced and stimulated by ozone depending on the concentration and the species. (4) Spore germination was in all cases reduced at elevated ozone concentrations. Further study of the composition and possible function of the globules is needed. By growing the fungus in liquid culture, the amount of tissue and its energy content could be compared with accuracy. This would also facilitate the isolation of the globules and analysis of their contents.
