logs buried into beds of hardwood sawdust, around the root zones of beeches, birches, willows or oaks. For indoor cultivation, I have had limited success using hardwood sawdust substrates rendered by other primary saprophytes. Expired Shiitake, Maitake and Reishi blocks seem to work the best. I recommend cultivators experiment growing sclerotia on recycled substrates in darkness, removing the sclerotia when mature, and implanting them in lignicolous soils to stimulate fruitings. Currently the modified natural model is the main method of cultivation in China.
Recommended Containers for Fruiting: Polypropylene bags for indoor cultivation. Trenchjlture outdoorTcan be framed with non-chemically treated boards around the root zones of candidate trees and protected with shade clothed, covered hoop-frames.
Yield Potentials: Not known. The natural model developed by the Chinese first yields sclerotia as the primary poduc and secondanly mu 3oms which are more often used for food than for medtcina Durooseslnlic id c ture, I have achieved a 6% yield (d. w/dw.) of dry mycel.um from a mal yeast sluny Yield efficiencies of sclerotia and mushrooms from Chinese Zhu Ling tree nurseries (a.k.a "Hog Tuber Farms") are not known to this author.
Form of Product Sold to Market: Sclerotia are exported from China, either whole or slice, and in are solcHn markets i 1 i i. Currently, there are no producers of this mushroom in North Amenca.

Me 'icinal Properties: This mushroom has been heralded to possess potent anti-cancer immuno-poteSn properties. However few scientific studie hav, acondu ted, and none by Western ■searchers D ing a visit to the Beijing Institute of Materia IV Ledica in October of 1983 Dr. Andrew * Dr Emanuelilzman, Gary Lincoff and myself were informed by e cited researchers hat wal e cts (tea) of this mushroom, when given to lung cancer patients rfter radiation therapy resuUed in complete recc in the majority of the patients after several years.

Miyaski (1983) also noted the anti-sarcoma properties of this fungus. Dr. Andrew Weil (1992) strongly believes this species deserves greater attention by Western medical practitioners.

^ Accc ngt< Bo&Yun-sun (1980, pp. 195), Chinese physicians are using extracts of the Zhu Ling sclerotia in the treatmen of «lung can ;er,ce n, cancer, esophagus cancer, gastric cancer, liver cancer, intestine cancer, leukemia, mammary gland cancer and lymphosarcoma. Flavor, Preparation & Cooking: The fleshy, above-ground mushroom is easily broken or chopped, placed into a frying pan or wok, and sauteed as one would do with Shiitake.
The sclerotia are usually made into a tea by placing 20-25 grams in a liter of water and boiling for 20 minutes. Additional water is added to offset that lost to evaporation. Since the sclerotia are extremely tough, and are difficult to extract, I leave the sclerotia chips in the water for several more soakings before discarding It should be noted that I have made tea of Zhu Ling & Reishi for more than 1000 people at various mushroom conferences over the past 7 years without a single report of a negative reaction.
Comments Zhu Ling sclerotia remain some of the least expensive of the imported medicinal fungi. Grown quasi-naturally in the temperate, mountainous Shansi Guu County of China, the sclerotia sell for about 1/2 the price of Reishi. Once the anti-cancer propeities of this fungus become better understood. and if proven, the value of Zhu Ling sclerotia is likely to increase.
The sclerotia are used medicinally whereas the fleshy and fragile fruitbodies, known as "Hog Tuber Flowers" are eaten as a gourmet mushroom. This is one of the softest Polypores I have encountered. Its excellent flavor, unique life cycle, medicinal propeities and scarcity are all factors that should encourage the development of indoor, controlled environment fruitings by cultivator entrepreneurs.

he teethed fungi have many representatives, some of which are exquisitely edible. Species belonging to the Genus Hericium are most notable. Her'cium erinaceus and H. coralloides produce prodigiously in culture and are the best flavored. Hericium abietis, a lover of conifers, is more difficult to cultivate. This group of mushrooms, with their snow-white, distinctive appearance have long been a favorite of woodspeople. Like Shiitake, the cultivation of this mushroom probably evolved from the astute observations of those who collected them from the wild.
