Pleurotus eryngii
Taxonomy and Naming
The Pleurotus eryngii species, also known as King Oyster or King Trumpet Mushroom, belongs to the Pleurotaceae family. The genus name Pleurotus derives from the Greek words 'pleuron', meaning 'side', and 'otus', meaning 'ear', referring to the mushroom's distinctive ear-like shape. The species name eryngii is derived from Eryngium, a genus of flowering plants in the family Apiaceae, upon which this mushroom is known to grow.

The mushroom is typically grown on a substrate composed of a mixture of organic materials, such as straw, wood chips, and corn cobs.
