The cultivation of shiitake (Lentinula edodes) in Argentina began in recent years; however, tree species commonly used as substrates in Southeast Asia or North America are not present. We assayed eight types of easily available local woods: "coihue" (Nothofagus dombeyi), "lenga" (N. pumilioi, "ñire" (N. antarctica), "roble pellin" (N. obliquai), eucalypt (Eucalyptus camaldulensis), pine (Pinus elliotit), "Parana pine" (Araucaria angustijolia), and willow (Salix babylonica). Two strains of shiitake were studied, using experimental blocks (1 kg) which contained the following substrate formulation: 80% sawdust, 10% wheat bran, 10% millet seed, 2% chalk, adjusted to 74% moisture. Blocks were incubated at 25 C for a month, and then subjected to a cold shock at 5 C for 7-10 days in order to promote fruiting. After induction, the blocks were placed in a room at 18±3 C, about 9 h/day of lighting, and watered daily. Fruit bodies were obtained from most wood types studied, with the exception of "Parana pine" and pine. The strain BAFC-2250 had higher biological efficiencies (BE), which were recorded in "roble pellin" (60.4%), "lenga" (52.3%), and eucalypt (26.5%). The highest mushroom yield was also shown by the strain BAFC-2250.
