Révay, Ágnes: The metabolism of Pleurotus ostreatus (Jacq. ex Fr.) Kummer, Pleurotus florida Block and Pleurotus cornucopiae Paul. ex Fr. from taxonomical and other viewpoints

the time of appearance of the fruit bodies in Pleurotus florida provide certain information to support its being an independent species. I express my thanks to Professors Dr. András Terpó and Dr. Tibor Simon for providing all the conditions which were necessary for making my work possible, and to Dr. Imre Rimóczi, Assistent Lecturer, who was of very great help in the theoretical and practical accomplishment of the examinations. The last step in determining the cellulose content was taken in the plant physiological Department of the University of Veterinary Science, for which I express my gratitude to the members of the Department.
