The Development of Grain Spawn

Mushroom spawn is used to inoculate prepared substrates. This inoculum consists of a carrier material fully colonized by mushroom mycelium. The type of carrier varies according to the mushroom species cultivated, although rye grain is the choice of most spavwi makers. The history of the development of mushroom spawn ior Agaricus brunnescens culture illustrates how spawn production has progressed in the last hundred years. 

Listed below are cereal grains that can be used to produce spawn. Immediately following this list is a chart illustrating some of the physical properties important to the spawn maker. 

RICE Utilized by few cultivators. Even when it is balanced to recommended moisture levels, the kernels tend to clump together owing to the sticky nature of the outer coat. 

MILLET Although having a higher number of inoculation points than rye, it is more difficult to formulate as spawn. Amycel, a commercial spawn-making company, has successfully developed a formula and process utilizing millet as their primary spawn medium. 

SORGHUM Has spherical kernels and works relatively well as a spawn medium but it can difficult To obtain. Milo, a Type of sorghum, has been used for years by the StollerSpavwi Spawn Company.
