Three edible species, Lyophyllum species and Armillaria mellea-judae introduced from Japan in 1979 and Auricularia auricula-judae from Taiwan in 1978 were selected for artificial- cultivation. The media, MSDS and MCDS for Lyophyllum species MHS and PDS for A. auricula-judge and MSDS and MHS for A. mellea were selected. The range of optimum pH for Lyophyllem species was pH 6.0 and pH 8.0 for A. auricula-judge, and pH 6.0 to 7.4 for A. mellea. The range of optimum temperature for the mycelial growth of Lyophyllnm species was 25℃ to 30℃ and 30℃ for A. auriculajude and 25℃for A. mellea. For the moisture content 75 to 80% (w/w) in the substrates, the mycelial growth of Lyophyllum species and A. auricula-judge was rapid, however, 65% (w/w) for A. mellea.
As the spawning substrates, wheat for Lyophyllum species oak sawdust for A. auricula-judge and poplar sawdust for A. mellea were selected, respectively.
In this experiment, yields of Lyophyllum species and A. auricula-judge were highest on the poplar sawdust added rice bran 20% (w/w). Lyophyllum species and A. auricula-judae for sources of new edible mushrooms seem to be possible.
