Message from the Faculty Member 【 Display / hide 】

  • 菌類，特にきのこ類の自然史を主な研究対象としています。きのこは，日々の食卓に彩りを添え，健康増進にも一役買っているなど，私たちの生活に身近な生物です。しかし，地球上には，私たちの想像をはるかに超える数の未知のきのこたちが潜んでおり，その多様性の全貌は明らかではありません。そこで私は，日本や中国東北部など，東アジアを中心とした地域の海浜，里山や亜高山帯・高山帯を主なフィールドとして，野外調査によりきのこ類の標本を収集し，形態的・生態的な特徴および遺伝子の情報をもとに，それらの系統分類や生物地理に関する研究を行っています。きのこやカビなどの菌類の視点から，自然環境の複雑さと，地球上の生物の多様性，そして生物と環境とのつながりを探っていきたいと考えています。ところで，人間社会においても，複雑性・多様性を認め，さまざまな分野とのつながりを保つことはとても大切です。学生の皆さんには，慶應義塾において論理的な思考力や表現力を養い，自らの目指す方向を見つけることを期待するとともに，専門性を磨きつつも幅広い視野を持ち，異なる分野へも積極的にアプローチすることを望みます。

    Research paper (scientific journal), Joint Work, Lead author, Corresponding author, Accepted

    　View Summary

    A subhypogeous sclerodermataceous fungus was collected in the Eucalyptus plantation of Ibaraki Prefecture, central Japan. Based on morphological observations and phylogenetic analyses using nuclear ribosomal DNA sequences, the present fungus was identified as Scleroderma capeverdeanum, belonging to Sclerodermataceae (Boletales). Scleroderma capeverdeanum is new to Japan and characterized by small-sized (4–10 mm in diam.), sessile basidiomata, yellowish to yellowish brown exoperidium with brownish, areolate to verrucose scales, and echinulate basidiospores. Japanese specimens of S. capeverdearnum are probably associated with introduced E. globulus, and therefore they are most likely exotic species introduced from Australia.

  • Revisiting Hebeloma (Hymenogastraceae, Agaricales) in Japan: four species recombined into other genera but three new species discovered

    Mycological Progress 21   447 - 472 2022.03

    Research paper (scientific journal), Joint Work, Accepted

    　View Summary

    Here, we present the results of studies of Japanese Hebeloma collections. The four species described by Imai as Hebeloma (H. fimicola, H. helvolescens, H. humosum, and H. tomoeae) are not from the genus Hebeloma, but are members of Agrocybe, Homophron, or Pholiota. Recombinations are made. Hebeloma crustuliniforme f. microspermum, described by Hongo, is a synonym of H. nanum. Three species of Hebeloma are described as new to science, all currently known only from Japan. Two of these species, H. asperosporum and H. cinnamomeum, are members of H. sect. Denudata while the third species H. citrisporum belongs to H. sect. Velutipes. Japanese records of H. cavipes, H. eburneum, H. hygrophilum, H. subtortum, and H. velutipes are validated. In total, fifteen species of Hebeloma are confirmed from Japan; this is compared with previous checklists.

    　View Summary

    Chimaphila umbellata</i> is a partially mycoheterotrophic plant, so the involvement of fungi is necessary at the time of germination. This species distributes in the northern hemisphere. In Japan they are found in Hokkaido, Aomori, Iwate, and Ibaraki prefectures. In Hitachinaka city, Ibaraki prefecture, the southern limit of the distribution, the number of individuals has dropped sharply making them in danger of extinction.</p><p>In order to clarify their germination conditions in the southern limit, seed packets were buried in various environments in autumn 2018. After 6 and 10 months, recovered packets were examined and germination was confirmed. The state of the germination was in an early stage where the embryo expands and breaks the testa. It is necessary to continue the investigation in order to identify the environmental conditions suitable for symbiotic fungi and germination.</p><p>Next, in order to compare the breeding status of populations in the southern and the northern (Hokkaido and Aomori prefecture) regions, we surveyed growing area in July to August 2019. As a result, it was not possible to confirm the breeding by the seedlings in all surveyed areas, but the growth density, the number of flowers and fruits were larger in the growing area in the northern part, and hence the possibility of seed breeding would be higher in these regions. In the southern limit, as major pollinator of <i>Chimaphylla umbellata</i> was lacked, artificial pollination is considered to be effective for better fruiting. Finally, population genetics analysis using next-generation sequencing revealed that populations in the southern limit are genetically uniform and that they have less genetic diversity than those in the north. It is necessary to take conservation measures as soon as possible in these areas.

    植物や動物は標本データからある程度の分布域を推測することができるが、きのこ類は標本情報と実際の分布域に大きな乖離がある。これはきのこ類の主体が菌糸や胞子であり、肉眼で確認できる子実体発生の有無だけでは、存在が見逃されてきただけ、という可能性を排除できないからである。本プロジェクトでは、1) 市民参加型調査による情報収集、2) 環境DNAによる対象種の検出、3) 種内の遺伝的多様性解析、などを通じ、きのこ類の国内分布域の北限および南限のパターンを推定する。特に最近の分布北上が強く示唆され、顕著な形態的特徴をもつきのこ類複数種を対象とすることで、前例のない精密な分布図を描くことを可能にする。

  • Unidentified specimens in herbarium can develop mushroom taxonomy: integration of accumulation of DNA information and fieldwork

    2018.03

    Chiba Institute of Science, Kasuya Taiga, Grant-in-Aid for Young Scientists (B), No Setting

    　View Summary

    Preservation status of DNA information of mushroom specimens housed for a long time in museum herbarium has been evaluated. If we cannot obtain DNA information among herbarium specimens, we conducted alternative fieldwork and collected new specimens to complement the DNA information. Moreover, species taxonomy of unidentified specimens of mushrooms preserved in Japanese museum inferred from morphological characteristics and DNA information has been studied. As a result, we detected several Basidiomycete mushrooms regarded to new taxa or new to Japanese mycobiota. Furthermore, the necessity of taxonomic reexamination such as the presence of cryptic species was shown in several known species of mushrooms in Japan based on morphological observations and molecular phylogenetic analyses.
