Cultivo de Pleurotus ostreatus y especies afines (Fungi: Pleurotaceae) sobre medios naturales semi-estériles / Cultivation of Pleurotus ostreatus and allied species (Fungi:Pleurotaceae) upon semi-esterile natural media

Pleurotus ostreatus (Jacq. ex Fr.) Quélet and its allies are edible mushrooms whose cultivation is succesful in parts of Europe and Asia. In Costa Rica only Agaricus bisporus has been commercially cultured, but requires elaborate facilities. The use of waste material (e.g. sawdust, rice straw, sugar cane debris) and mon-controlled environmental conditions suitable for easy artisanal cultivation of Pleirotus ostreatus is reported here.
