Key points

  • Mushroom tumor on Flammulina velutipes has become the main disease during the off-season cultivation of F. velutipes while the causal organism has remained unknown
  • The present study was aimed at identifying the pathogen confirming its pathogenisity following Koch's Postulates, characterizing it using morphological, physiological, biochemical and molecular features, and studying its current distribution
  • We determined that mushroom tumor is a new bacterial infection disease caused by Ochrobactrum pseudogrignonense
  • It produces tumor-like structures on the surface of the substrate, and inhibits the formation of primordia and fruiting of F. velutipes
  • The molecular studies showed that this new pathogen is closely related to Ochrobactrum based on 16S rRNA sequences
  • This is the first time that Ochrobactrum has been shown to be a pathogen of a mushroom

Citation abstract

Mushroom tumor on Flammulina velutipes has become the main disease during the off-season cultivation of F. velutipes while the causal organism has remained unknown. The present study was aimed at identifying the pathogen confirming its pathogenisity following Koch's Postulates, characterizing it using morphological, physiological, biochemical and molecular features, and studying its current distribution. We determined that mushroom tumor is a new bacterial infection disease caused by Ochrobactrum pseudogrignonense. It produces tumor-like structures on the surface of the substrate, and inhibits the formation of primordia and fruiting of F. velutipes. The molecular studies showed that this new pathogen is closely related to Ochrobactrum based on 16S rRNA sequences. This is the first time that Ochrobactrum has been shown to be a pathogen of a mushroom.
