This study was conducted to investigate the phylogenetic relationships of the members of the genus Agrocybedistributein Korea based on the morphological characteristics of the fruiting bodies and establish a taxonomic key to the species of Korean Agrocybe. A total of 54 specimens, that is, 50 specimens (mushroom collection at the MAST, RDA) originally collected from 18 different locations in Korea from 1981 to 2000 and four additional mushroom specimens obtained in this study in the last two years were examined using light optical microscopes and Scanning Electron Microscopes(SEM). Based on the results of the identification and classification, seven formerly recorded species in Korea were recognized: A erebia, A praecox, A arualis, A cylidracea, A farinacea, A semiorbiciharis, and A pauludosa. Morphological features of the specimen no. 6644A, 6710A, and 6718A stored at MAST appeared to be identical to those of A. erebia. However, 6001A showed different spore size and further investigation is required for the specimen. The specimen no. 10886 and 8138A corresponded to A praecox Although three specimens(7602A, 6252A and 7612A) originally assigned to Agrocybe sp. showed similar microscopic structures to A praecox, since they produce gourd-shaped cystidia, further clarification is required All eight specimens, A312, 16176, 7927A, 8523A, 8531A, 8548A, 8622A and 10894A showed the same morphological characteristics as A awalis, and A cylindracea was found to be a cultivated species. Specimen no. 24096 and 6196A corresponded to A farinacea, and 5679A and 2067A were identified as A. paludosa. Specimen no. 6194A, 6205A and two of formerly recorded species as A. sp., 7793A and 9793A fall into A senuorbicuka-is However, microscopic study showed that 4-spore type basidiospores were more abundant than 2-spore type basidospores in specimen no. 6194A, 6205A and 7793A. Due to the lack of the specimen, further confirmation of A sphalerornorpha was not possible. A. sp.(5387A) collected from Mt Hanla in Jeju island was confirmed as A farina, and newly designated Korean common name as “갈색우단볏짚버섯”A sp.(9765A) collected in Suwonsi, Kyunggido was confirmed as A dcaa, and newly named in Korean as "큰볏짚버섯". In the present study, a key to the species of the genus Agrocybe found in Korea was established according to the Moser's taxonomic key based on the -presence of the inner veil and spore color and it allowed for the identification of 10 species belonging to the section Agrocybe and section Aporus.
