Many Entoloma were collected at Mt. Baiyang, Mt. Jiry, Mt, Sunun, Mt, Naejang and Mt. Manduck to September 1991 from June 1991. These spercies were identified. According to the resulting. Entoloma readii, E. cinerascens, E.padiceum, E.squamulosum and E. umbilicatum were newly to Korea.

Many species of the genus Entolama were collected at Mt. Jiri National Park, Mt. Baikyang National Park, Mt. Sunun Provincial Park and Mt. Balwang from June, 1991 to september, 1991.These sepecies were identified. According to the results, Entolama convexum, E. roanense, E.clavipes,E.tephreum, E.ochraceumand E.weberi were newly recorded in Korea.These species were described and their Korean names were designed.

Apexes of basidia in Rhodophyllus(synonyum of Entoloma) muraii var. albus are divided into four sections or depressed in the center. A spore is formed by inflation of the apex of the sterigma. The apex of the sterigma is swollen and changed from a papilla through a penisform and a club into a globeform. Six spots of globose spore are regularly or irregularly depressed with hilum axes. Finally the spores are cuboid. Basidia of Entoloma squamiferrum are developed from hymenium layer of crator-shaped parabasidium. Apex of basidium is flat or depressed in the center. Although four sterigmata are developed, only two sterigmata are symmetrically swollen to two spores in certain basidia. It means that two sterigmata among four sterigmata are infertile. The apex of the sterigma is swollen into a paillaform, and then turned into a penisform. It is swollen from a clubform into a globeform. Six spots of the surfaces of globose spore are deperssed with hilum axes. Finally the spore is cuboid, and then it is released from hilum. Four sterigmata of papillaform of E. violaceobrunneum are developed from cartor-shaped basidium. The apex of sterigma is swollen to a small globeform. And then it is swollen to a clubform. The clubform is again swollen to a ellipticalform, and then more than six spots of spore surfaces are ramomly depressed with hium axes. When the depression of surface of a elliptical spore is over, it is the multi-angular spore of the heterometrical-form.

The species of the genus Entoloma recorded in Korea until now are arranged with Korean Entoloma monography. It was made with modified keys of classification of Hesler and Noordeloos. On the basis of it, the genus Entoloma of Korea is classified into 7 subgenera, 10 sections, and 80 species.

Four sterigmata of papillaform E. violaceobrunneum are developed from crator-shaped basidium. The apex of sterigma is swollen to a small globeform. And then it is swollen to a clubform. The clubform is again swollen to a ellipticalform, and then more than six spots of spore surfaces are ramdomly depressed with hilum axes. When the depression of surface of a elliptical spore is over, the spore is a heterodiametrical spore of multi-angular.

Basidia of Entoloma squamiferrum are developed from hymenium layer of cartor-shaped parabasidium. Apex of basidium is flat or depressed in the center. Although four sterigmata are developed, only two sterigmata are symmetrically swollen to two spores im certain basidia. It means that two sterigmata among four sterigmata are imfertil. A spore is formed by inflation of the apex of the sterigma. The apex of the sterigma is swollen into a paillaform and then turned into a penisform. It is swollen from a clubform into a globefrom. Six spots of the surfaces of globose spore are depressed with hilum axes. Finally the spore is cuboid, and then it is released from hilum.

Seven species of the genus Entoloma were collectted from the areas of Mt. Naejang National Park, Mt. Jiri National Park, Mt. Sunun Provincial Park and Mt. manduck from June, 1991 to September, 1991. These species were identified new to Korea : Entoloma subvile, E. bruneomarginatum, E. minutoalbum, E. subplanum, E. melleipes, E. perabidum, and E. pyrium.

1990년 5월부터 10월까지 내장산 국립공원, 선운산 도립공원 및 만덕산 일대에서 외대버섯들을 다수 채집하였다. 이 외대버섯들을 동정한 결과, 한국미기록종으로 확인된 것은 다음과 같으며 이들에 대하여 한국보통명과 한국어 설명을 첨가하였다. Entoloma subfarinaceum(가루외대버섯아재비) : 균모(갓)는 소형, 배꼽형, 회갈색, 가루비늘, 가장 자리에 줄무늬가 있다. 주름살은 올린주름살 또는 바른주름살, 가장자리는 물결형이다. 자루(대)는 가늘과 비틀리면, 회갈색, 윗쪽은 가루비늘이 분포 하나 아래는 밋밋하다. 포자는 중형, 5각형, 연낭 상체와 측낭상체는 없다. 여름에 혼효림의 낙엽속의 흙에 산생 또는 군생한다. E. viriginicum(처녀의대버섯) : 균모는 소형, 배꼽형, 회갈색, 가장자리에 줄무늬가 있다. 주름살은 배불뚝형, 간격은 좁고, 끝블은 주름살이다. 자루는 원통형, 거의 청색이다. 포자는 중형, 대부분 7각형으로 결절형, 연낭상체와 측낭상체는 없다. 여름에 고목의 이끼속에 군생한다. (중략)
