PEREIRA, G. et al. Characterization of a relict native forest with annual fructification of the edible fungi Boletus loyo Phil. ex Speg. Quebracho (Santiago del Estero) [online]. 2016, vol.24, n.1, pp.18-19. ISSN 0328-0543.

Boletus loyo (Basidiomycete) is an edible ectomycorrhizic fungus associated to Nothofagus species. In general, the biotic and abiotic conditions for its growth are largely unknown. This study was located on a site corresponding to a relic native forest in the Cordillera de la Costa mountain range, Bío-Bío district, Chile, where B. loyo has been collected for years. The local vegetation was characterized using transects, registering tree, shrubs, and climbing species frequency at different forest strata. The chemical properties of the soil were also characterized. The upper stratum is dominated by Nothofagus obliqua, Cryptocarya alba, Gevuinaavellana, and Aextoxiconpuntctatum, shows abundance of climbing and semi-climbing plants such as Lapageria rosea, Herreria stellata, and Chusqueaquila. The lower stratum is dominated by Ugni molinae and Sophora macrocarpa. The granitic forest soil has high organic matter content, low pH, medium-to-low levels of Nitrogen, Phosphorus, and Calcium, and high levels of Potassium, Magnesium, Iron, Manganese, Zinc, and Copper.
