Growing Yellow Oyster Mushrooms
The yellow or golden oyster mushroom (Pleurotus citrinopileatus) is native to eastern Russia, northern China and Japan. It grows in clusters producing boldly coloured yellow caps with a delicate, velvety texture.
You’re unlikely to find these golden delights in a supermarket near you due to their short shelf life and delicate structure.
Yellow oyster mushrooms are sweet and nutty when well cooked. Under cooked mushrooms may taste a little bitter. Braised golden oyster mushrooms and onions with sweet sherry, white pepper and nutmeg have been a mouthwatering addition to Sunday brunch.
Yellow oyster mushrooms will grow on a wide range of materials including sugar cane mulch, straw, hardwood, paper and coffee grounds.
For beginners we recommend starting with straw or chopped sugar cane mulch. Supplementation can be added in the form of coffee grounds or bran but will increase the chances of contamination.
White oyster mushrooms are considered to be a side-fruiting mushroom compared to the king oyster or button mushroom which are top-fruiting mushrooms.
Growing oyster mushrooms in buckets is a great project for first timers and more experienced cultivators alike. You can grow your own mushrooms at home using sugar cane mulch, straw or the cellulose rich material of your choice in conjunction with either cold or hot water pasteurisation.
Simple and easy to do using a few household items.
Humidity can be managed through a diligent misting and fanning regime, however the introduction of a humidifier and humidity controller can help automate the process and ensure consistency.
Adding a 6L humidifier and controller to a greenhouse with the addition of a USB fan is a quick and easy way to make a low cost fruiting chamber that delivers excellent results.
Mushrooms require humidity to grow. We recommend using a mini-greenhouse. Spraying the inside walls of the greenhouse will help raise humidity. A cheap humidifier can be used to automate the process.
It’s important to ensure that the grow kit has fresh air exchange. Mushrooms produce carbon dioxide and will grow long and leggy in search of more oxygen.
Check the product pages for species specific requirements.
Alternatively you can build a Shotgun Fruiting Chamber (SGFC) from a few common items found easily in your local hardware store.
Yellow oyster mushroom mycelium is incredibly vigorous. Initially it is finer in appearance and structure than white oyster.
The mature spawn will often begin to form primordia within days of colonisation, this is indicative of it preparing to fruit. The maturing mycelium will produce yellow liquid metabolites which are a completely normal byproduct.
Any primordia which has formed prematurely, or in-vitro can be removed prior to using the spawn as usual.
In order to grow, yellow oyster mushroom grow kits will need to be opened exposing the fully colonised substrate to fresh air and humidity.
Pale yellow clusters of coral-like primordia will form on the surface of the substrate. These clusters will develop into mushrooms.
For beginners, we recommend allowing the kit to begin forming a pin-set (primordia) before opening the bag. The high levels of the humidity will encourage the formation of large clusters of primordia which can be released from the bag by making a cut around the pin-set.
Pink oyster mushrooms will colonise both grain spawn and substrates very quickly. Full colonisation can often expected within 10 – 14 days. Store above room temperature at approximately 26 degrees Celsius (77f) for optimum colonisation speeds.
Keep at temperatures between 18 & 26 degrees Celsius to trigger pinning. It’s important to maintain humidity as high as possible at 95% RH.
Yellow oyster fruiting blocks may be opened and exposed to trigger the formation of primordia, otherwise primordia will eventually form within the bag due to the high humidity levels.
Maintain the mushrooms at temperatures above 26 degrees Celsius (77f) for fruiting body development. Humidity should be between 80 – 95%RH.
