Popis:	The rate at which 19 isolates of Cryptostroma corticale grew on 3% malt agar varied considerably but the growth of each isolate was optimal at 25°C. The isolates also varied considerably in their ability to grow in young sycamores (Acer pseudoplatanus) in the glasshouse and in 15-year-old trees in the field. Growth rates on agar and in the host were not related but isolates which grew most rapidly in young sycamores in the glasshouse had the greatest tendency to become black on Sabouraud dextrose agar and on malt agar. The results did not support the hypothesis that the 1976–77 outbreak of sooty bark disease in England was associated with a more virulent strain of the fungus.
