引起花椒角斑的一个菌绒孢(Mycovellasiella)新种

本文报道引起花椒(Zanthoxylum bungeanum Maxim)角斑病的一个新种一花椒菌绒孢(Mycovellosiella zanthoxyli Y. L. Guo & Z. M. Cao, sp. nov.)o该菌与寄生在花椒属(Zanthoxylum sp.)植物上的花椒生尾孢[Cercospora fagarina (Hansf.) Chupp]近似,二者的子实体均生于叶背面,扩散型,无子座,分生孢子梗主要着生在表生菌丝上,但后者的分生孢子梗非常长而较窄(100.0-250.0 × 5.0 μm),分生孢子短而宽(40.0-100.0、6.0-8.0 μm),因此本种为一新种。在芸香科(Rutaceae)尚无菌绒孢属真菌报道。文中为新种提供了拉丁文简介、描述及图。模式标本保藏在中国科学院微生物研究所真菌标本室(HMAS)。

报道生于豆科植物沙冬青Ammopiptanthus mongolicus上的链格孢属真菌一新种,沙冬青链格孢Alternaria ammopiptanthi。此种不同于已从豆科植物上报道的5个长喙链格孢种（复喙链格孢A. multirostrata、决明链格孢A. cassiae、猪屎豆生链格孢A. crotalariicola、瓜尔豆链格孢A. cyamopsidis和长喙链格孢A. longirostrata）,主要是其分生孢子的长喙不分枝和孢身细瘦。研究过的模式标本（PSNXAAFS 267852）保存在宁夏农林科学院植物病害标本室。     

Emericella omanensis,a new species from Oman soil

A new species ofEmericella isolated from forest soil in the Oman,E. omanensis, is described and illustrated. It differs from the other known species of the genus in having bivalvate ascospores with a tuberculate or verruculose convex wall. The new species is compared with the closely related speciesE. desertorum andE. echinulata.     

Cystobasidiopsis nirenbergiae, a new agaricostilbomycete (Pucciniomycotina)

A new genus, Cystobasidiopsis, and a new species, Cystobasidiopsis nirenbergiae, are described for a fungus isolated from an arable loess soil in Ahlum near Braunschweig, Niedersachsen, Germany. An integrated analysis of morphological, ecological, ultrastructural and molecular data indicates that the new species belongs to the Chionosphaeraceae within the Agaricostilbales. Relevant characteristics of the new species are discussed and compared with those of related taxa.     

New genera, species, and improved phylogeny of Glissomonadida (Cercozoa)

Glissomonadida is an important cercozoan order of predominantly biflagellate gliding bacterivores found largely in soil and freshwater. Their vast diversity is largely undescribed. We studied 23 mostly newly isolated strains by light microscopy and sequenced their 18S rDNA genes; nine represent new species. For two misidentified ATCC 'Heteromita triangularis' strains, we establish novel gliding genera and species: the sandonid Mollimonas lacrima, the only glissomonad forming anterior and posterior pseudopodia, and Dujardina stenomorpha, a strongly flattened member of the new family Dujardinidae. A new strain from Oxfordshire grassland soil is the first reliably identified isolate of the virtually uniflagellate, smooth-gliding glissomonad genus, AllantionSandon, 1924. Phylogenetic analysis and cytological features reveal Allantion to be a member of Allapsidae. Sandona limna and Bodomorpha prolixa from Lake Baikal and Sandona hexamutans from volcanic Costa Rican soil are described as new species. Fifteen glissomonad strains were from grassland beside Lake Baikal. We describe two as new species of Sandona (S. heptamutans and S. octamutans); the others included strains of Sandona and Allapsa species that have already been described; and three were new species of Sandona and Allapsa but these died before being described. We discuss the ecological and evolutionary significance of these new strains.     

Alternaria jesenskae sp. nov., a new species from Slovakia on Fumana procumbens (Cistaceae)

Alternaria jesenskae sp. nov. recovered from seeds of a shrubby perennial plant Fumana procumbens (Cistaceae) in Slovakia is described and illustrated. The new taxon can be clearly separated from the other related large-spored and filament-beaked Alternaria species based on sequences of the ITS1, 5.8S and ITS2 region as well as by its distinctive morphology. Even though the molecular data have shown close relatedness with A. multirostrata, the new species is morphologically most similar to A. tomatophila distinguished primarily by the pronounced colony pigmentation, conidial septation and beak branching.     

石耳属一新种(子囊菌门)

本文描述了地衣型石耳属一新种,周鳞石耳.新种脐叶体上表面以周边皮层碎片上翘而形成的大量准鳞芽,类似于淡腹鳞石耳,但是,不同之处在于新种脐叶体下表面黑色,覆以大量同色而多分枝的假根以及具有不同的地理分布.从而呈现为地理替代现象.文中为新种提供了拉丁文特征提要、英文描述、图片与地理分布图以及新种及其相关种的检索表.     

中国粘菌XII:无丝菌属一新种
