Abstract: 본 발명은 표고(Lentinus edodes)의 개량종인 참송이버섯(Chamsongi mushoom)의 톱밥배지의 다수확 재배방법에 관한 것으로, 통상의 표고버섯 재배시 톱밥배지를 개별적으로 생육하는 방법 대신 7~9개의 톱밥배지를 하나로 균사결합( Mycelia cohesion)시키고, 생육 초기 배지에 온습도의 변화 등 흑변처리 조작을 통해 오염율을 줄이고 송이버섯 모양의 참송이버섯 발생량을 증대시킬 수 있는 재배방법이다. 
       본 발명에 따른 참송이버섯 재배방법은 기존의 재배 방법보다 약 26%의 생산량 증가가 있었고 침수 및 재입상 시 작업시간이 약 1/5로 감소되었으며, 무엇보다도 기형(奇形)보다는 정형(定形)의 버섯이 더 많이 발생하였다. 
     참송이버섯(그림 1)은 표고버섯의 개량종으로서 표고버섯과는 달리 갓이 벌어지지 않고 대가 굵게 형성되어 표고버섯과는 완전히 다른 형태적 특징을 갖는 새로운 품종이다. 이 버섯은 수차례의 조직분리와 계대배양(Subculture) 및 실험재배를 통해 선발 육종한 신품종으로서, 국립종자관리소에 품종생산판매신고(신고번호; 09-0003-2003-1) 및 품종명칭을 등록(등록번호; 명칭 2003- 589)한 버섯이다.
