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 home growers!
When the mushrooms 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.
