Abstract: The present invention is directed to the field of dipteran pest control in the commercial production of mushrooms. The present invention is directed to preparations comprising mushroom spawn, compost, and casing mixed with thermophilic, spore forming bacteria and supplement, as well as methods for the use of such preparations for the control of Dipteran pests and the production of improved mushroom crops.

Abstract: A method of sawdust-based cultivation of Shiitake (Cortinellus Shiitake) and a cultivation water tank used for the method in which a top portion of a cultivation bag which includes a cultivation bed (sawdust-based substrate) is cut to expose a top surface of the cultivation bed and water is poured into a gap between the bag and bed; and a cultivation water tank comprises a framework, water tanks arranged in the framework, sawdust-based substrates arranged in the water tank, a latticed frame, water sprinklers, an air blower and illuminators, a pump connected to the water pipe and the exhaust pipe through a pipe, exhaust pipes provided at a drain pipe so that water may not overflow onto the top surface of the sawdust-based substrates which is characterized in that water is circulated to refrain mushrooms from fruiting and growing from the side and bottom faces of the sawdust-based substrates, but to grow only from the top surface of sawdust-based substrates.

Abstract: The present invention describes new and distinct horticultural varieties of higher Basidiomycetes mushroom grown in submerged culture. Specifically, the new varieties of species of the genus Tremella offer superior yields of mushroom one-cell biomass rich in essential amino acids and vitamins and polysaccharide glucuronoxylomannan.

Abstract: A sterilizable cultivation system is provided for growing selected organisms for use in biological applications and the cultivation edible fungi. A sealable, sterilizable container holds a growth substrate in a sterile condition. A separate, adhesive vent filter is provided, which is adhereable to a vent opening in the container. The vent filter is gas permeable and allows gas exchange between the interior of the container and the ambient environment, but prevents the passage of microbes and other organisms into or out of the container. This gas exchange prevents excess carbon dioxide from accumulating in the container and allows necessary oxygen into the container in order to maintain an appropriate growth environment for the selected organisms. The vent filter may be combined with the container (a) during manufacture of new containers, or (b) in the field by the end-user on new containers or on re-cycled containers.

Abstract: The invention concerns intraspecific hybrids of Agaricus bisporus capable of bearing fruit at relatively high temperature and without roughing-in, and the method for obtaining them consisting in a step of cross-breeding in particular between a first and a second Agaricus bisporus, one of which at least belongs to the burnettii variety, and a step of selecting the resulting hybrids having the characteristics mentioned above. The cultivation of the resulting hybrids is easier and less expensive than the standard method of cultivating mushrooms.

Abstract: A method of sawdust-based cultivation of Shiitake (Cortinellus Shiitake) in which a number of cultivated primordiums are decreased simply by elevating temporarily a temperature into a zone between 20 degree C. and 40 degree C. during/between a cultivation step and a growing step, thus adjusting a number of grown mushroom fruiting bodies.

Abstract: The present invention provides improved mushroom cultivation materials which are amenable to improved uniformity of application to mushroom beds. The invention features such materials having particulate indicator therein having a color which is discernable from the organic substrates of the cultivation materials. The application may be followed under incandescent, fluorescent or ultraviolet light or in accordance with other means.

Abstract: Disclosed are novel culture media for the artificial or industrial cultivation of Sparassis crispa (Sparassis crispa Wulf.:Fr), comprising larch-tree sawdust and/or chips extracted with heated water or vapor, and methods for producing the same.

Abstract: A covering material for stacks and beds for mushroom cultivation made up of 50 to 80 percent by volume filter cake from paper manufacturing and 20 to 50 percent by volume aggregate such as peat, vegetable fibers, milled limestone and/or marl with improved water storing capability and reduced nutritive content.

Abstract: A strain of chanterelle (C. cibarius Fr.Fr.) designated SNGT2-A is described herein. SNGT2-A can be grown in axenic culture as vegetative mycelia. SNGT2-A has a DNA fingerprint that distinguishes it from all other C. cibarius strains tested.
