Pleurotus eryngii habitat and frequency

Pleurotus eryngii, commonly known as King Oyster Mushroom or Trumpet Royale, has a wide distribution and can be found in various habitats around the world.

Habitat:

Substrate: Pleurotus eryngii is primarily a saprophytic mushroom, meaning it feeds on decaying organic matter. It commonly grows on the decaying roots of various plants, particularly on the roots of thistles (such as Eryngium species), which is where its specific epithet "eryngii" comes from. It can also be cultivated on straw or other agricultural wastes.

Natural environments: In the wild, Pleurotus eryngii can be found in grasslands, meadows, open woodlands, and disturbed areas with decaying plant material. It prefers temperate and Mediterranean climates.

Cultivation: Pleurotus eryngii is extensively cultivated worldwide. It can be grown indoors under controlled conditions using substrates such as straw, sawdust, or agricultural byproducts.

Frequency: Pleurotus eryngii is considered a relatively common and popular mushroom, both in the wild and in cultivation. Its widespread cultivation has made it more readily available in markets and grocery stores compared to some other mushroom species. However, the frequency of encountering Pleurotus eryngii in its natural habitat can vary depending on geographic location, local climate, and availability of suitable substrates.
