|The Golden Oyster Mushroom|
Il'mak (Elm Mushroom in Russian)
|Native to forested areas subtropical China, southern Japan and surrounding regions.|
Natural habitate includes Asian hardwoods, especially elm, oaks, poplars and beech. Often found growing on logs and stumps.
|Characteristics and Qualities|
The Golden Oyster Mushroom are one of the most commonly cultivated gourmet mushrooms thanks to their ease of cultivation, beautiful appearance and distinctive taste. Like most other Oysters, the Pleurotus citrinopileatus grows quickly and aggressively and will grow on a wide range of substrates.
Golden Oysters require a larger spawn percentage (~20%) in order to ensure full colonization on most substrates. This is higher than most other strains and can increase cost of production.
Due to its sub-tropical origins the Pleurotus citrinopileatus is best suited for cultivation in warmer climates and cropping yields are much less than their Pink Oyster cousins.
The down-sides to the Golden Oyster are their extreme fragility. When harvesting, it's best to harvest in clusters to avoid damage; Golden Oyster's don't transport well which limits their suitability for large scale commercial production. Their gold luster also quickly diminishes after harvest.

"Paul Stamets book on gourmet mushroom cultivation is the bible of mushroom cultivation. If you are looking for comprehensive information on how to grow mushrooms both at home and commercially then Growing Gourmet and Medicinal Mushrooms is a great book to have; it's a lifetime of knowledge in one book." (Paul Thomson, Founder of Hear Me RAW.)
Enhancing the Golden Colour of the Pleurotus Citrinopileatus
The golden cap of the Pleurotus citrinopileatus is directly related to the intensity of the light within the fruiting chamber. Increase your lighting levels and you will deepen the rich golden colour of the mushroom. Light levels between 500-1000LUX are optimal with no noticeable increase in colour richness beyond 1000LUX.
Golden colour diminishes when strain is over cultured.
The yield potential of the Golden Oyster mushroom are not as high as the Pink Oyster mushroom. Yields are increased greatly by using grain spawn over sawdust spawn when mixing with substrate.
Golden oyster mushrooms take well to cotton-seed adjusted substrates and their yield increases substantially.
First and 2nd flush are generally good harvests, after which yields decrease greatly.
The fruit-bodies of the Golden Oyster mushroom are very delicate and much easier to harvest in clusters. The cultivator should encourage cluster formation where possible.
Selling at Market
Golden Oyster mushrooms are a beautiful looking mushroom that sell well at markets, especially to Asian customers who are more familiar to them. Golden Oysters are suitable for drying (though their lush golden colour diminishes whilst drying).
Pleurotus citrinopileatus is thought to help aid pulmonary emphysema 1 and much like the similar P. ostreatus, will likely help reduce cholesterol.
