Grey Oyster (Pleurotus ostreatus)

These mushrooms are very easy to fruit and are well suited for beginners.

They are very versatile and can substitute well into many mushroom recipes.


Grey Oyster mushrooms (Pleurotus ostreatus) are the most common type of oyster mushroom and can be found across the world. This species is very forgiving to cultivate and a great option for beginner and experienced home growers.

When grey oysters first start pinning they’re a lovely dark grey-blue colour which fades to a light grey as they mature. Grey oysters like a lot of air exchange and will grow large caps under the right conditions. When starved of fresh air they stretch and produce longer stems rather than big fan-like caps (but you want to avoid this as the stems tend to be quite tough).

Grey Oyster mushrooms have a mild, slightly sweet taste with a woodsy characteristic that goes particularly well in egg dishes like omelets or quiches.
