The Pleurotus eryngii species-complex in Kurdistan region of Iran.
Members of the Pleurotus eryngii species-complex are known to be well distributed in the Kurdistan region of Iran. In a survey conducted during 2003-05, fourteen wild populations of the Pleurotus eryngii species-complex were collected from Sanandaj, Hane Gelan and Saral areas. Eco-morphological studies and pairing tests showed that all isolates belong to P. eryngii. The isolates were associated either with Prangos and Pimpinella with smaller spores or Ferula haussknechtii with larger spores. Ferula haussknechtii is thought to be a new host species of P. eryngii in the world.
