White Bud Mushroom

Strain: M 7218

 compost mushrooms flush growing in bed

Qualities:

  • Excellent, medium-size mushroom strain
  • Ability to produce larger as well as smaller mushrooms
  • Very good quality for the fresh market

Characteristics:

Versatile strain, very popular strain type worldwide. It also has the ability to produce both high-density medium and larger sized fruitbodies and maintains high yields in both cases, even though picking is easier when the fruitbodies are grown to medium size. The caps are smooth and rounded.
