Pleurotus ostreatus
Pleurotus ostreatus, known here as the “Grey Oyster” or “Oyster Mushroom,” is the most common member of the oyster family.
Widely cultivated in Asia and across the Atlantic, more and more small European growers are taking an interest in this wood-loving mushroom, which can sometimes be found in our forests during winter.
History
The natural habitat of the grey oyster mushroom is mainly in the undergrowth of temperate regions throughout the Northern Hemisphere. They are typically found on old hardwood logs, especially after the first frost of the year.
The first records of oyster mushroom cultivation on wooden logs are relatively recent and come from Germany (Flack, 1917). Shortly after, an American-Chinese trio—Block, Tsao, and Hau—optimized this cultivation technique. Since then, the grey oyster has become the third most cultivated mushroom in the world, after Shiitake and Button mushrooms.
Like all mushrooms grown at FloydFungi, this species is a primary decomposer, a saprophyte. It starts the wood decomposition cycle by digesting lignin and cellulose, turning them into organic matter more easily assimilated by other organisms, known as secondary decomposers. Recent studies have shown that the oyster, to compensate for nitrogen deficiencies in old wood, has developed a predatory technique: it paralyzes, kills, and digests small nematodes (roundworms) encountered along its path. Don’t worry—our oysters are vegan; we supplement our wood with organic wheat bran for nitrogen!

Taste Experience
Grey oyster mushrooms have a delicate, refined flavor with a smooth, melting texture. They also have a subtle earthy note that makes them unique.
Some describe their taste as subtly reminiscent of seafood, while others detect a hint of anise.
Chefs often break the mushroom along its fiber line, from cap to stem, then slice as needed.

Cellular Protection Research
Glycoproteins found in the Oyster mushroom (Pleurotus ostreatus) — lectins — are being studied for their role in cellular defense mechanisms. Research explores their ability to influence the cell cycle and promote apoptosis (natural cell death).
