Lentinula edodes

Shiitake

Strain: M 3782

 

M 3782 substrate shii-take mycelium

Qualities:

  • excellent all year round strain
  • very fast incubation
  • quality fruit bodies
  • very tolerant in humid conditions
  • suited for pasteurized as well as sterilized substrate

Characteristics:

This Shiitake is very versatile.  When grown at temperatures below 18°C, it produces beautiful fruit bodies of the donko-type: dark-brown, nicely scaled, heavy and slender-stemmed, mushrooms have a good shelf life.  In warmer growing circumstances the flesh becomes thinner and the colour lighter.  Mushrooms also appear between flushes. With cultivation on sterilized substrate blocks, a ripening phase of 4-5 months needs to be taken into account. This strain is very popular in Europe.
