title: Slippery Scar: A New Mushroom Disease in Auricularia polytricha.
abstract: A new disease, the slippery scar, was investigated in cultivated bags of Auricularia polytricha. This fungus was isolated from the infected mycelia of cultivated bags. Based on morphological observation, rDNA-internal transcribed spacer and 18S sequence analysis, this pathogen was identified as the Ascomycete Scytalidium lignicola. According to Koch's Postulation, the pathogenicity of S. lignicola to the mycelia of A. polytricha was confirmed. The parasitism of this fungus on mushroom mycelia in China has not been reported before.
