Evaluation of mycelium growth of shiitake strains, of production in Eucalyptus logs and of physical alteration of the wood. The growth rate of 8 strains of shiitake (LE-95/01, LE-96/18, LE-96/13, LE-98/55, LE-98/47, LE-95/02, LE-95/06 and LE- 95/07), the production of these in Eucalyptus logs at the first flush, and consequent alterations in physical characteristics of the wood due the inoculation with the strain LED- 96/18 were evaluated. The mycelium growth was inoculated in SA medium (sawdust enriched with crumb-agar), in the absence of light, at 25ºC. In log cultivation, each strain was inoculated in 40 logs of Eucalyptus grandis with 1 meter length and 9 to 14 cm of diameter. The logs were maintained at 25ºC ± 3 and relative humidity of 75-90%, for 6 months. Subsequently, the first flush was accomplished, and it was verified: (1) the lineage LE-95/01 obtained the largest production and slower mycelium growth in vitro; (2) there was slow growth of the strain LED-95/06 and low mushrooms production; (3) the moisture of the logs inoculated with strain LE-96/18 increased along the cultivation, whereas the specific mass decreased.
