Outbreaks of Brown Rot due to the above-named fungus are not at all common in America, although European growers encounter a similar trouble frequently. It is better known on the apple than on the pear in this country. The blossoms, fruits and branches are susceptible, and when affected the various phases are referred to respectively as blossom blight, Brown Rot, and Brown Rot canker. Recently a Brown Rot canker has been described from Oregon, but it has not been definitely determined whether the fungus concerned is S. cinerea or another species.
