Pleurotus eryngii (king trumpet mushroom)

Pleurotus eryngii (King oyster mushroom, eringi)

King oyster mushrooms, or Pleurotus eryngii, are the same cardoncellos I had gorged myself on in Puglia about five years ago, when I had them deep-fried.

Recent research has shown that P. nebrodensis is closely related to, but unique from, Pleurotus eryngii, which also occurs in the Mediterranean Basin and is associated with plants in the family Apiaceae.

LMEs have been known to be produced by many species of so-called white rot basidiomycetous fungi, including: Phanerochaete chrysosporium, Ceriporiopsis subvermispora, Trametes versicolor, Phlebia radiata, Pleurotus ostreatus and Pleurotus eryngii.

Pleurotus eryngii (also known as king trumpet mushroom, French horn mushroom, king oyster mushroom, boletus of the steppes, trumpet royale) is an edible mushroom native to Mediterranean regions of Europe, the Middle East, and North Africa, but also grown in many parts of Asia.
