    Cytospora is a genus of ascomycete fungi. Cytospora species are known as plant pathogens.

    Pathology

    Cytospora canker was observed by Ouellette et al. (1965)[1] in all the plantations of white and Norway spruces examined in the Province of Quebec, as well as in some natural stands of indigenous spruce. Disease incidence was particularly high in the Grand-Mère and Saint-Lazare plantations where it had been present since at least 1943 and 1955, respectively. Periods favourable to infection had occurred at fairly regular intervals, and the aggressiveness of canker development varied year by year. Rainfall, temperature, and disease intensity were not clearly correlated.
