Abstract
The mycelial growth speed of Pleurotus ostreatus (POS 09/100) and Lentinula edodes (LED 96/13) was evaluated in four substrates based on Simarouba amara sawdust, Anacardium giganteum sawdust, Euterpe precatoria seeds and Musa sp. AAB stems. The loss of organic matter of the substrates and the mycelial vigor of the strains studied were also evaluated. The greatest mycelial growth for P. ostreatus occurred in the substrates formulated with S. amara sawdust (29.45 cm3/day) and A. giganteum (27.58 cm3/day). The best performance for L. edodes occurred in the substrate of A. giganteum (13.22 cm3/day), followed by the S. amara (11.30 cm3/day). The most intense rates of vigor were presented in the E. precatoria substrate which was added with brans. The most significant loss of organic matter for both mushrooms occurred in the substrate formulated with a supplement of A. giganteum (54% for P. ostreatus and 61% for L. edodes). There was no mycelial growth in the formulation prepared with banana stem in both mushrooms tested. Key words: Edible fungi, mycelial growth, alternative substrates.
Highlights
The importance of mushrooms cultivation is significant because it represents an efficient choice to enable the use of organic matter for bioconversion into high- value added products, such as edible mushrooms (SalesCampos et al, 2010)

The objective of the present study was to test the viability of regional residues, aiming at their future use in the cultivation of edible mushrooms, by evaluating the mycelial growth speed of P. ostreatus and L. edodes in substrates formulated with regional lignocellulosic residues
Summary
The importance of mushrooms cultivation is significant because it represents an efficient choice to enable the use of organic matter for bioconversion into high- value added products, such as edible mushrooms (SalesCampos et al, 2010). Pleurotus ostreatus and Lentinula edodes are among the species with a great economic importance for cultivation. According to the study of Bononi et al (1999), its worldwide consumption has increased significantly, and some European and American countries have been importing this mushroom more and more. The consumption of P. ostreatus has increased significantly in the last years because of its outstanding taste and great availability in the market, occupying the fourth position in the world production of edible mushrooms (Bononi et al, 1999). The Pleurotus gender fungi compete with the other edible fungi due to their growth speed and ability to adapt to a series of sub-
