Abstract

Among the 22,000 known species of mushrooms, about 2,000 are edible and only 100 species are cultivated worldwide. Wild mushrooms species may be very promising for cultivation studies and future insertion in the national market of edible mushrooms. Thus, the objective of this work is to certify the identification of the wild edible mushrooms of the Collection of Algae, Cyanobacteria and Fungi Cultures of the Institute of Botany (CCIBt) and to investigate the optimum temperature of mycelial growth in vitro, aiming to study its potentialities of cultivation for future applications. The identification of the wild edible mushroom isolates from the CCIBt will be certified through the amplification and sequencing of the ITS region of rDNA (barcoding for fungi). The isolates will be cultured in BDA culture medium and submitted to mycelial growth tests at different temperatures. Research on the potential of wild mushroom cultivation may lead to the discovery of higher productivity isolates and better adapted to local conditions than the commercially available species.
