How to Collect Spores

Spore Use Agar Mycelium Growing

A culture arising l'rom cloning is fundamentally di Jerent than a culture originating from spores. When spores are germ' ated, many different strains are created, some incompatible with one another. A cultivator will not know what features will be expressed until each and every strain is grown out to the final stage, that of mushroom production.T1 is form of genetic roulette results in very diverse strains, some more desirable than others. Mushroom spores are collected by taking a spore print....

The Development of Indoor Morel Cultivation

Mushroom Indoor Cultivation

All attempts at controlled, indoor Morei cultivation failed, until Ron Ower succeeded in 1982. By his own admission, the discovery of Morel cultivation was more by accident than design. And, Ron Ower told me that his experiences growing Psilocybe mushrooms combined with an accident in the laboratory led to success. He revealed he had used the casing formula outlined in my first book, Psilocybe Mushrooms amp their Allies S tamets 1978 as the sclerotia-forming formula. Under pres sure from...

Choosing a Sterilizer aka the Retort or Autoclave

Diagram Steam Steriliser

Although home-style pressure cookers are i leal for sterilizing agar media and for small-to-medium batches of grain, they have insufficient capacity for the sterilization of bulk substrates. The problems faced by the mushroom cultivator in Thailand or the U ted States are the essentially the same. In developing countries, the sterilizer is often a make-shift, vertical drum, heated by fire or gas. A heavy lid is placed on top to keep the contents contained. The boiling of water generates Figure...

Spore Mass Inoculation

Spore Mass Inoculation

By far the simplest way to grow mushrooms is to broadcast spores onto prepared substrates outdoors. First, spores of the desired species must be collected. Spore collection techniques vary, according to the shape, size, and type of the mushroom candidate. For gilled mushrooms, the caps can be severed from the stems, and laid, gills down, on top of clean typing paper, glass, or similar surface. See Figure 15. A glass jar or bowl is placed over the mushroom to lessen the loss of water. After 12...

Formulas for Creating Grain Spawn

Moisture content plays a critical role in the successful colonization by mushroom mycelium of sterilized grai. . If the grain is too dry. gro vth is retarded with the mycelium forming fine threads and growing slowly. Should too much water be added to the grain, the grain clumps, and dense, slow growth occurs. Higher moisture contents also encourage bacterial blooms. Without proper moisture content, spawn production is hampered, even though all other techniques may be perfect. The optimum...

Mushroom Cultivation Room Design

Mushroom Greenhouse Design Structure

Purposesi To recapture as many mushrooms possible whichcan not be realized in controlled environment growing rooms.This building can solve a dilemma constantly confronting the growing room personnel to maximize mushroom yield while not jeopardizing future crops as contaminants become more common as the cycle comes to completion. By the third or fourth flush, yields are in a state of precipitous decline. Rather than discarding this mycelium, additional harvests can be realized, with minimum...

Stumps as Elatforms for Growing Mushrooms

Oyster Large Log Inoculation Methods

Stumps are especially suitable for growing gourmet mushrooms. There are few better, or more massive platforms, than the stump. Millions of stumps are all that remain of many forests of the world. In most cases, stumps are seen as having little or no econonr potent' J. These lone tombstones of biodegradable wood fiber offer a unique, new opportunity for the mycologically astute. With selective logging being increasingly practiced, cultivating gour met and medicinal mushrooms on stumps will be...

The Phase H Chamber Steam Pasteurization

Chamber Construction Mushroom Compost

A second method calls for the placement of straw in a highly-insulated room into which steam is injected. This room is known as the Phase II Chamber. Before the straw is loaded into the Phase II chamber, it must be moistened. This can be done simply by spread ng the chopped straw over a large surface area, a cement slab or plastic tarpaulin to a depth no greater than 12 inches. Water is sprayed on the straw via sprinklers over a two to four day pe riod. The straw is turned every day to expose...

Build A Paddy Mushroom Grow House In Thailand

Straw Mushroom Growing

Fruitings, although not nearly as well as supplemented, composted rice straw. One study showed that the best supplement for wheat straw is wheat bran 5 and or cotton hulls 10 . See Li et al., 1988 . The pH optimum for fruiting falls between 7.5 - 8.0. Recommended Containers for Fruiting Trays, bags. Outdoor methods use no containers. The substrate is shaped into long rectangular mounds, narrowing at the top. The frames are covered with loose rice straw, cloth or plastic to retain humidity....

Interior surfaces not biodegradable

Mushroom Green House

Interior surfaces such as the walls, counter-tops, shelving, etc. should not be able to support mold growth. Wood and sheet rock should be avoided. The floors should be painted several times or overlaid with a chemically resistant, cleanable mat. When using a paint, use a non-mildewing enamel. (Caution Do not use paint containing fungicides, particular any containing tributyl tin oxide, an extremely dangerous toxin to both humans and mushrooms.) Counter-tops can be made of stainless, steel or a...
