The Oyster Mushroom was first described scientifically in 1775 by Dutch naturalist Nikolaus Joseph Freiherr von Jacquin (1727 – 1817) and named Agaricus ostreatus. (In the early days of fungus taxonomy most of the gilled mushrooms were included in the genus Agaricus.) In 1871 German mycologist Paul Kummer transferred the Oyster Mushroom to the genus Pleurotus (a new genus that Kummer himself had defined in 1971), giving it its currently accepted scientific name.

Let us know some of your successes with this mushroom in companion growing!!!

Oyster mushrooms contain ergothioneine, a unique antioxidant exclusively produced by fungi.
Oyster mushrooms contain significant levels of zinc, iron, potassium, calcium, phosphorus, vitamin C, folic acid, Niacin, and vitamins B-1 and B-2. They boost the immune system and support healthy liver, kidneys and lungs.

As with all Oyster mushrooms, Blue Oysters need plenty of fresh air to develop normally. High carbon dioxide levels from mushroom metabolism will accumulate in sealed growing environments and can reduce cap size and elongate stems severely. Fruiting in open humidity chambers with frequent fresh air exchange will produce best possible yields.
