Occurrence of Disease Caused by Cladobotryum varium on Flammulina velutipes in Korea

Abstract

Cladobotryum varium infects the fruitbody of Flammulina velutipes during its cultivation. In the early stage of infection, white mycelia of C. varium partially attacked young fruitbody and eventually killed whole fruitbody during fruitbodies development. White fungi pathogen isolated from F. velutipes cultivation farm were investigated in pathogenicity and morphological feautres. The pathogen was identified as Cladobotryum varium. In asexual stage, conidiophores formed, long and conidiospores with single septum were shaped in chains, in size. Size of chlamydospores were with septa.
