Harvest Hints: If mushrooms form through holes in the plastic, harvesting is fast and efficient. Clusters of these ear shaped mushrooms pop off without residual substrate debris.

Form of Product Sold to Market: Fresh and dried. The greatest volume of this mushroom is sold in
dry form.Although dark when dried, these mushrooms lighten to brownish in color as they rehydrate,
usually true to form. The rubbery and cartilaginous consistency is strangely appealing.

Nutritional Content: 8-10% protein, 0.8-1.2% fat, 84-87% carbohydrates, 9-14% fiber, and 4-7%
ash. (Ying, 1987; Chang & Hayes, 1978). Moisture content of fresh mushrooms is usually within a
few percentage points of 90%.
Medicinal Properties: Ying (1987) reports that this mushroom is 80 & 90% effective against Ehrlich
carcinoma and sarcoma 180 respectively. The supporting references are in Chinese.
A hematologist at a medical school in Minnesota pricked his finger in a blood clotting test, and
when his blood failed to clot, the ensuing investigation traced the cause to the Wood Ear mushrooms
he had eaten the night before at a Chinese restaurant. In the United States during the 1970's, when
