Substrates for Fruiting: Essentially the same hardwoods that are recommended for Shiitake sup-

port good fruitings of this species. In Asia, Acacia spp. are widely used. The ideal pH range is
between 6.5-7.0. Wheat straw has been used successfully (Jianjun, 1991), especially when sawdust
spawn is used.

Recommended Containers for Fruiting: Polypropylene bags and bottles. Each should be punctured with 10-20 holes after full colonization (25-40 days after inoculation) to localize primordia

Recommended Cropping Containers: Polypropylene bags and bottles. One method uses cylindrically shaped polypropylene bags, 6-8 inches in diameter, that are cut open at both ends and laid
horizontally to build a wall of exposed surfaces. From these open ends, the Wood Ear mushrooms

filter patch. These bags are
emerge. Others use polypropylene spawn bags fitted with a microporous
usually punctured to encourage mushroom formation around the bags, or are partially opened at
top to elicit a surface flush of mushrooms. I personally prefer the puncture hole technique.
Yield Potential: 1/4 to 1/2 lb. of mushrooms per 5 lbs. of supplemented sawdust. Logs produce for
several years, yielding at best, 20% of their wet mass into fresh mushrooms over 3-5 years.
