But other varieties are appearing in local markets including shiitake pronounced she-TAH-key a darker and stronger-flavored cousin of the common button mushroom. The shiitake Lentinula edodes begins life as an invisible network of pale spidery threads which burrow through the dead tissue of various hard-woods oak beech chestnut or the shii tree from which the mushroom derives its name . The threads or mycelia digest the wood and convert it into fungal tissue. When the wood has deteriorated sufficiently the fungus produces fruit. In the wild the mushrooms that pop out of the wood form spores which the wind blows to new logs starting a new life cycle. In China shiitake have been cultivated on notched logs stacked in evergreen forests since as early as . 1100. It is believed that Chinese growers introduced shiitake cultivation techniques to Japanese farmers who named the mushroom and were later responsible for its spread eastward. Centuries later in 1972 the . Department of Agriculture lifted a ban on importing live shiitake cultures and the . shiitake industry took off. Between 1986 and 2000 total . production of shiitake increased from less than 1 to million pounds while the price dropped from to per pound. Shiitake can be grown on synthetic as well as natural logs. Composed of sawdust and supplemented with millet and wheat bran synthetic logs may produce three to four times as many mushrooms as natural logs in one-tenth of the time. Also environmentally controlled houses allow for the manipulation of temperature humidity light and the moisture content of the logs to produce the highest possible yields. These advances in cultivation .
