The anamorphic fungus
Sporothrix inflata, known as a soil-borne fungus with worldwide distribution, was isolated for the first time from the cortex and central cylinder
of living and dead roots of healthy and diseased oak trees (
Quercus robur and
Q. petraea). Isolation frequencies of
S. inflata from oak roots varied according to the health status of trees, oak species, study sites, soil depth and root diameter. Colony
morphology and growth rate of isolates are influenced by colony age and type of culture medium.
