中文摘要: 作者对主要采自我国西南、保存在中国科学院昆明植物研究所标本馆隐花植物标本室(HKAS)的400多号环柄菇属Lepiota(蘑菇科,蘑菇目)标本,用形态学和解剖学方法进行了分类研究,共鉴定出本属19个种和5个变种,其中8新种,即:滴抱环柄菇L.guttulaspola H.C.Wallg,假小环柄菇L.pseudocristata H.C.Wang,鳞柄环柄菇L.furfuraceipes H.c.wang&zhu L.Yang,紫褐环柄菇L.purpureo-brunea.H.C.Wang,黄肉环柄菇L.flavotrana H.C.wang,狭抱环柄菇L.graciliospora H.C.Wang,红褐环柄菇L.rubro-brunnea H.C.Wang和臧氏环柄菇L.zangiana H.C.Wang;2新变种,即:细环柄菇黑鳞变种L.clypeolaria avar.nigrosquamosa H.C.Wang和梭孢环柄菇台湾变种L.magnispora var.taiwanensis H.C.Wang;2个我国新记录种,即:红斑环柄菇Lerythrosticta(Berk.& Broome)Sacc.和黄褐环柄菇L.luteocastanea E.Horak;l个新组合,即:梭孢环柄菇黄褐变种L.luteocastanea var. fulva (Bon) H.C. Wang。本文中作者提出环柄菇属最狭义的概念,把其分为四个组,即:环柄菇组Lepiota sect.Lepiota sect. Lepiota,冠盖环柄菇组Lepiota sect.Liloceoe Bon,卵孢环柄菇组Lepiota sect. Ovisporae (J.E. Lange) Kuhner和距孢环柄菇组Lepiota sect. Stenosporae (J.E. Lange) Kuhner。作者对四个组的概念和范围进行了讨论,并给出分组检索表,对每个组又都给出分种检索表。对种及种以下的分类单元的担子果形态和显微结构特征进行了详细描述并对少部分种的担子果形态和所有种及变种的重要显微结构进行了绘图。此外还讨论了各个种或变种与近缘种的区别,总结了其世界分布、国内分布范围和生境。
英文摘要: Over 400 specimens of the genus Lepioa (Pers.: Fr.) Gray (Agaricaceae, Agaricales) mostly collected from southwestern China and deposited in the Herbarium of Cryptogams, Kunming Institute of Botany of the Chinese Academy of Sciences (HKAS), were studied taxonomically based on morphological and anatomical characters. As a result, 24 taxa were identified, of which 8 species (L. guttulaspora H. C. Wang, L. pseudocristaia H. C. Wang, L, furfuraceipes H. C. Wang & Zhu L. Yang, L purpureo-brunea. H. C. Wang, L. flavotrama H. C. Wang, L graciliospora H. C. Wang, L. rubro-brunnea H. C. Wang and L. zangiana H. C. Wang) and 2 varieties (L. clypeolaria var. nigrosquamosa H. C. Wang and L. magnispora var. taiM'anensis H. C. Wang) are new to science, and 2 species are new to China (L erythrosticta (Berk. & Broome) Sacc. and L. Luteocastanea E. Horak). One new combination is made (L. magnispora vax.fulva (Bon) H. C. Wang). The diagnosis given by the author in the thesis is defined for the genus Lepiota in the narrowest sense. In this genus, four sections are recognized, viz. Lepiota sect. Lepiota, Lepiota sect. Lilaceae Bon, Lepiota sect. Ovisporae (J. E. Lange) Kuhner and Lepiota sect. Stenosporae (J. E. Lange) Kuhner. The delimitatons of them are discussed. Keys to these sections and taxa of each section are given. Detail description on the basidiocarp and important microscopical characters of each species and variety is given. Illustrations about the basidiocarp of some species and important microscopical characters of all species and varieties are provided. In addition, the differences between species or varieties and their relatives are discussed. The habitat and distribution of all taxa are also summarized.
