Matsutake Mushrooms have been collected for many years, but have just recently become a popular source of extra income for numerous people. This page provides tips that will help in picking and in assuring a future crop. BiologyMatsutake mushrooms are simple plants known as fungi. Unlike green plants, fungi cannot use sunlight to make food, but fungi use other living organisms or dead organic matter for food. Fungi have many important roles in the forest. They help break down and return dead plant material to the soil for use by other plants. They are a food source for many animals including insects, squirrels, and deer. They can help plants and trees resist disease. The fleshy portion or "mushroom" of the Matsutake is really the fruiting portion of the fungus. A mushroom is similar in function to an apple or other fruit in that it carries the reproductive structure. Instead of seeds, millions of tiny spores are produced along the gills of the mushroom. These spores are spread by wind when the cap of the mushroom is open. Like a seed, spores will germinate and grow when conditions are right. Fruiting or mushroom production requires specific conditions. A lack or rain, for example, can result in a season where few mushrooms are produced. According to studies in Japan, the thickness of the duff layer and the density of the trees also influence Matsutake production. Matsutakes receive their nutrition through the living roots of nearby trees in a special relationship where both trees and fungi benefit. This is called a mycorrhizal relationship. The main portion of Matsutake's are below ground and consist of interwoven rootlike threads called mycelium. The mycelium fibers surround and penetrate tree roots, hence the mycorrhizal relationship. These "extra roots" enable the tree to obtain more nutrients and water; and helps protect the tree from disease-causing organisms. The fungus, in turn, obtains vital food products it cannot manufacture itself. Neither the trees or the Matsutake can survive without each other. Maintaining an abundance of mycorrhizal fungi is critical to overall forest health. ResearchAt present we do not know the specific forest conditions in Oregon and Washington that will enhance Matsutake mushroom growth and production. We also do not know the effects of repeated and prolonged picking. Therefore, it is difficult to set mushroom collection levels that will assure long-term mushroom growth. The Deschutes, Umpqua, Willamette, and Winema National Forests are cooperating with scientists to study these issues. The long-term effects of picking will be compared with mushroom production. Timber harvest methods on mushroom production will also be evaluated. Studies will also take place on artificially inducing fruiting and germination. Location and SeasonThe Matsutake season usually starts the first part of September. The first mushrooms come up in the higher elevation forests of fir, hemlock, and ponderosa pine. Later the Matsutake can be found in almost all forest areas including pure lodgepole pine above 4500 feet elevation. Check with mushroom buyers to locate potential picking areas. Buying & SellingMost Matsutake mushrooms are shipped directly to Japan where they are used for food and flavorings in soups, etc. Matsutakes are sold based on five separate grades. The mushrooms are graded by age and any damage. Buyers can be found on main roads and are highly visible. Buyers will help with identification, cleaning, care, and grade. Prices will vary greatly by the grade. The prices also vary daily depending on the mushroom market. PermitsPermits are required for harvesting mushrooms on national forest land. You should check with the local ranger district for their specific conditions. Buyers are not allowed to operate in some national forest areas. Other areas allow buyers by permit only. Check first before picking or buying. Mushroom harvesting is prohibited in areas such as National Parks, National Forest Wilderness, and the mushroom research area located on the Chemult Ranger District of the Winema National Forest. Picking RequirementsImproper picking techniques can destroy Matsutake mushroom habitat. Three simple steps will ensure future crops of Matsutake.
Remember, raking the duff or litter layer can ruin mushrooms and destroy future crop potential. |
