1. Identification

After completing all the initial steps, prepared paddy straws (bundle or small cuttings) are spawned with mushroom seed or mushroom spawn. The bundles or bags of spawned paddy straw are then kept inside mushroom production chamber.

12 – 15 days after spawning, unwanted species of mushroom can be seen growing on the surface of mushroom beds. Identification points of these species of mushroom are as follows:

  • Colour: Colour of the unwanted mushroom is white.
  • Appearance: It is beak shaped.
  • Stipe: Mushroom stipe is thin and small. Stipe becomes elongated within few days (2-4 days). Now mushroom opens with black spores.

In this post we are going to share the images of unwanted mushroom in mushroom production units.
