Abstract
This report is the first of cobweb disease on Agaricus bisporus in Korea. Cobweb on both fruit bodies and casing soils were observed on several mushroom farms in Gyeongbuk Province, Korea. Classical and molecular characterization indicated that the causal agent is Cladobotryum mycophilum. The isolated fungus was used to inoculate fruiting bodies of A. bisporus and caused the same symptoms.
