Abstract
The result of study on the morphological feature of fruitbody, soil characteristics and enviromental condition of habitat of Tricholoma giganteum in Korea was as follows: The Pileus was $5.5{\sim}28.0\;cm$ in diameter and $1.5{\sim}3.7\;cm$ in thickness, indicating of yellowish white, beige, or ivory color. The lamellae were $18{\sim}20\;mm$ in diameter; the stipe was $9.0{\sim}35.7\;cm$ long and $1.0{\sim}3.0\;cm$ wide. The spores were $3.5{\sim}4.8{\times}5.7{\sim}7.4\;{\mu}m$ in size, ellipsoid, hyaline and the spore deposit white. The basidia were $6.1{\sim}7.0{\times}32.2{\sim}39.2\;{\mu}m$ in size. Cheiloystidia were $3.5{\sim}4.4{\times}30.5{\sim}33.1\;{\mu}m$ in size. Pileipellis were $3.3{\sim}4.4{\times}33.0{\sim}55.0\;{\mu}m$ wide and had clamp connection. Stipitipellis were $2.2{\sim}3.3{\times}88.0{\sim}93.1\;{\mu}m$ in size. Texture of soil in habitate of T. giganteum was silty loam, and organic materials content and available phosphate content in this soil were high as comparision to general soil in Korea. In the time of the mushrooms sprout, the room temperature indicated $25{\sim}27^{\circ}C$, their humidity showed $80{\sim}83%$, and the brightnesses were 328 Lux.
한국산 새로운 왕송이 버섯의 형태적 특정 및 서식지의 토성과 환경조건을 조사한 결과는 다음과 같다. 왕송이버섯의 자실체 형태적 특징은 갓과 대가대형으로 갓의 폭은 $5.5{\sim}28.0\;cm$, 두께는 $1.5{\sim}3.7\;cm$, 색택은 연노랑색 또는 베이지색 또는 아이보리색을 띄며, 주름살의 폭은 $18{\sim}20\;mm$, 대의 길이는 $9.0{\sim}35.7\;cm$, 직경은 $1.0{\sim}3.0\;cm$로 굵다. 포자의 색은 흰색이며 크기는$3.5{\sim}4.8{\times}5.7{\sim}7.4\;{\mu}m$이고 타원형이다. 담자기의 크기는 $6.1{\sim}7.0{\times}32.2{\sim}39.2\;{\mu}m$, 주름살말단세포는 $3.5{\sim}4.4{\times}30.5{\sim}33.1\;{\mu}m$, 갓표피상층세포는 $3.3{\sim}4.4{\times}33.0{\sim}55.0\;{\mu}m$로 폭이 넓고 클램프가 있으며, 대표피상층세포는 $2.2{\sim}3.3{\times}88.0{\sim}93.1\;{\mu}m$ 이다. 이 버섯의 서식지 토성은 미사질 양토이며 서식지 토양이 일반토양에 비해 유기물 함량과 유효인산 함량이 높았다. 버섯발생시 실내온도는 $25{\sim}27^{\circ}C$, 습도는 $80{\sim}83%$, 광도는 328 Lux이었다.
