中国果疣衣属地衣的研究

果疣衣属地衣系子囊菌门Ascomycota,子囊菌纲Ascomycetes,茶渍衣亚纲Lecanoromycetidae,鸡皮衣目Pertusariales,鸡皮衣科Pertusariaceae的成员。由于粉色果疣衣Varicellaria rhodocarpa在中国的首次发现,使中国地衣区系中新增添了一个属：果疣衣属Varicellaria。该属迄今已知仅含三种,即粉芽果疣衣V.kemensis,八孢果疣衣V.carneonivea及粉色果疣衣V.rhodocarpa。果疣衣属为壳状地衣,地衣体微薄,膜质;子囊盘茶渍型,单个或数个聚生于瘤状果疣中;类侧丝多分枝并呈网状缠绕;子囊内含单孢或八孢;子囊孢子大型(长度为200～400μm),双胞,无色透明,椭圆形;孢子壁厚达27μm;与鸡皮衣属不同之处在于前者子囊内含双胞孢子,后者子囊内含单胞孢子。由于该属在中国是首次被发现,为了进一步的研究,文中还提供了该属迄今已知的全部三种的分种检索表。粉色果疣衣以其地衣体基本无粉芽和遇Pd呈负反应而区别于粉芽果疣衣,以子囊内含单孢而区别于八孢果疣衣。通过薄板层析法首次从该种髓部检测出茶渍衣酸。其地理成分为北极高山种,主要分布于欧洲的挪威、瑞典、芬兰、阿尔卑斯山脉,喀尔巴阡山脉、苏格兰以及北美洲;在亚洲迄今只见于日本与中国。

Contributions to the faunistics and bionomics of Staphylinidae (Coleoptera) in northeastern North America: discoveries made through study of the University of Guelph Insect Collection, Ontario, Canada

Staphylinidae (Rove Beetles) from northeastern North America deposited in the University of Guelph Insect Collection (Ontario, Canada) were curated from 2008-2010 by the first author. The identification of this material has resulted in the recognition of thirty-five new provincial or state records, six new Canadian records, one new record for the United States and two new records for eastern Canada. All records are for subfamilies other than Aleocharinae and Pselaphinae, which will be treated in future publications as collaborative projects. Range expansions of ten exotic species to additional provinces and states are reported. The known distributions of each species in northeastern North America are summarized and presented as maps, and those species with a distinctive habitus are illustrated with color photographs. Genitalia and/or secondary sexual characters are illustrated for those species currently only identifiable on the basis of dissected males. The majority of the new records are in groups that have been recently revised, demonstrating the importance of curation and local insect surveys to the understanding of biodiversity, even for taxa and areas considered 'relatively well-known'.

河北小五台山叶生丝孢菌

小五台山自然保护区位于河北省西部,为河北省第一高峰。变化悬殊的地形,使其由低谷到亚高山草甸呈明显独特的垂直植被类型分布带,山势陡峻,谷路隘险,具有华北地区罕见的森林植被及丰富的植物资源。狭谷陡峰,葳蒐险奇的地形地貌,又形成了多变的气候特征,因此蕴藏着相当丰富的真菌资源。作者1990年8月在该地区考察期间,共采集涉及林木、农作物、花卉、蔬菜等植物病害标本240份。本文报道小五台山的丝孢菌(Hyphomycetes)14属40种,其中有二个新种:(木来)木菌绒孢(Mycovellosiella coni Y.L.Guo, sp. nov.),五味子色链隔孢(Phaeoramularia schisandrae Y.L. Guo, sp. nov.)和7个中国新记录种:沼泽尾孢(Cercospora paludicola Speg.),白面子菌绒孢[Mycovellosiella ariae(Fuckel) U. Braun],薯蓣菌绒孢[Mycovellosiella dioscorae(Vassiljevski) Pons & Sutton],当归柱隔孢(Ramularia angelicae v. Hohnel),白芷柱隔孢[Ramularia heraclei(Oud.)Sacc.),莴苣柱隔孢(Ramularia lactucosa Lamb. & Fautr.)和虎耳草柱隔孢(Ramularia saxifragae Syd.)。(木来)来木菌绒孢(Mycovellosiella coni Y.L. Guo, sp. nov.)生于山茱萸科(Cornaceae)华尔特氏掠子木(Cornus walteri Wanger.)叶上。子实体生于叶背面。次生菌丝体表生。无子座。分生孢子梗1-3根从气孔伸出或作为侧枝单生于表生菌丝上,近无色,分枝,曲膝状,1-2个隔膜,5.0-50.0 × 2.5-4.0 μm。分生孢子圆柱形,无色,链生并具枝链,0-4个隔膜,6.5-45.0 × 2.0-4.0 μm。在山茱萸科尚无菌绒孢属的报道,且该菌与已报道的尾孢属菌形态特征也不同,故定为新种。五味子色链隔孢(Phaeoramularia schisandrae Y.L. Guo, sp. nov.)生于五味子科(Schisandraceae)五味子[Schisandra chinensis (Tunz.) Baill.]叶上,子实体生于叶背面。菌丝体内生。具子座。分生孢子梗紧密簇生,浅青黄褐色,不分枝,曲膝状,1-5个隔膜,20.0-75.0 (-95.0) × 4.0-5.0 μm。分生孢子圆柱形,近无色,链生并具枝链,1-4个隔膜,15.0-40.0 × 3.0-4.0 μm。五味子科既无尾孢菌属也无色链隔孢属的报道。文中为新种提供了拉丁文简介、描述和图,新记录种进行了简要描述。研究的标本保藏在中国科学院微生物研究所真菌标本室(HMAS)。
