The Golden Oyster is an attractive fast growing mushroom that fruits easily on a wide range of ligneous substrates. The mushrooms grow in clusters of small, thin fleshed, funnel-shaped bright yellow caps.

The flavor improves dramatically with thorough cooking. Mushrooms tend to be bitter and sour when raw or undercooked.

The Golden Oyster is not as productive as other oyster mushrooms, So expect only 2 flushes before the substrate is exhausted. The temperature must be at least 65F to initiate fruiting. These mushrooms also need plenty of fresh air to develop normally. High carbon dioxide levels from mushroom metabolism will accumulate in sealed growing environments and may reduce cap size severely.

Our Edible and Gourmet Spawn Starter Kits include everything you need to begin the generation of edible and gourmet mushroom spawn. These kits include the edible mushroom culture and a number of our pre-sterilized bags of rye berries.

Small kit includes one bag and 3cc culture syringe.
Medium kit includes four bags and a 10cc culture syringe.
Large kit includes ten bags and a 10cc culture syringe.

Each bag contains just over 1 pound of precooked and pre-sterilized rye berries that can be used for primary spawn generation with culture injection through the self-healing injection site.

The Bags included with this kit are specifically designed for primary spawn generation. If you are seeking a Grow Kit product for contained fruiting of Oyster Mushrooms, please see our Oyster Mushroom Grow Kits.

To use, unfold the Bag, allowing the extra bag material to stand straight up.

Locate the small foam disk sealed and attached in a plastic housing near the base of the Bag. This disc is the self-healing injector site. Note: The disc will be covered by a small plastic shield. Do not attempt to remove the plastic covering the disc, you will inject through it. Sterilize a small section of the outside of the Bag (on the plastic shield) directly over the foam disc with an alcohol soaked wipe. With the same alcohol soaked wipe, sterilize the needle on your culture syringe.

Inoculate the substrate with culture syringe(included) solution by inserting the needle through the plastic shield and foam disc at the previously sterilized spot and squirting 1cc of culture solution into the mixture. Mix culture solution thoroughly by shaking the syringe before injection. (Faster colonization can be achieved by squirting solution into several locations in the substrate mixture).When injection is finished, slowly remove the needle and the foam disc will seal the injection site (no need to tape). DO NOT insert the needle through the white filter patch.

Return the inoculated bags back to the shipping box and place in a dark, warm location (species specific). Allow the bag to remain extended so gaseous exchange through the filter patch is not blocked.

The bags may be gently shaken to distribute the colonizing grains for faster spawn run. Colonization time will depend on the species used and incubation temperatures.

Once fully colonized the rye berry spawn may be used to inoculate other bulk mediums such as pasteurized straw, sawdust, hardwood blocks, ect.
