To enhance the utilization of Larch(Larix leptolepis Gorden) wood, the sawdusts were tested as cultivating media for Lentinus edodes(Mori 290) by varying the composition of the media. The economic efficiency for producing mushrooms from larch sawdusts was evaluated. The results are as follows. 1. Larch sawdust was as much efficient as oak sawdust in the growth of the mycelia and production of good quality of oak mushrooms. 2. The mushrooms were able to be harvested starting six months after beginning the cultivation. No differences were found among the qualities of the mushrooms produced by various treatments. 3. The contents of lignin(28.6-28.7%) in the fresh sawdust of larchwood are higher than those in the residues of the used media(18.2%). But lignin content of 1% NaOH extracts(30.4-34.4%) in fresh sawdust of larch was lower than those in the residues(68.0%). 4. The production of mushroom was relatively high to be 29.7-31.5%(760-780g.)/2.5kg pack) of mushroom weight. The net profit estimated was 1,475Won per pack.
