齿梗孢属二新种

报道分离自土壤中的齿梗孢属 Scolecobasidium 二新种:椭圆齿梗孢 Scolecobasidium ellipticum 和小孢齿梗孢 Scolecobasidium microsporum。椭圆齿梗孢与亚马逊齿梗孢 S. amazonense、粗腐植齿梗孢 S. crassihumicola 和倒卵齿梗孢 S. obovatum 形态近似,区别在于 S. amazonense 的分生孢子倒卵形,常在分生孢子基部形成一横隔膜,同样 S. crassihumicola 的分生孢子也仅具一横隔膜;S. obovatum 的分生孢子(10-25×4-6μm)明显地较新种的大,且表面光滑,因此容易区分。小孢齿梗孢与嗜粪齿梗孢 S. coprophilum、腐植齿梗孢 S. humicola 和小疣齿梗孢 S. verruculosum 分生孢子形态有些相似,但新种的分生孢子明显小于 S. coprophilum(6-12.5×2.8-4.2μm)和 S. humicola(7-13×2.8-4μm, Matsushima,1971)的,分生孢子梗也明显较后两者的短;此外,新种的分生孢子密生刺突,而 S. verruculosum 分生孢子表面遍生小疣,使它们陪此易于区分。二新种的模式标本(干制培养物)保存在山东农业大学植物病理学标本室(HSAUP)。     

中国的膨孢组镰孢菌(英文)

膨孢组镰孢菌Fusarium在自然界中广泛分布。该组包括4个种:木贼镰孢菌F.equiseti,藨草镰孢菌F.scirpi,长脚镰孢菌F.longipes和紧致镰孢菌F.compactum。这4个种均产生腹背不平行弯曲的大孢子。分离获得并描述了其中的3个种。木贼镰孢菌F.equiseti是镰孢菌中最常见的种之一,它产生典型的腹背不平行弯曲的大孢子,大孢子的顶细胞和足跟状基细胞明显伸长,菌落因缺乏红色素而呈黄褐色。藨草镰孢菌F.scirpi是比较少见的种类,它的典型特征是在典型的十字形产孢细胞上产生大量的小型分生孢子。由于它在PDA培养基上容易发生小孢子缺乏型的变异,因此,常常被错误地鉴定为木贼镰孢菌F.equiseti。长脚镰孢菌F.longipes的大孢子最容易与其他种的大孢子区分,它的顶细胞和基细胞均极度延长。当长脚镰孢菌F.longipes菌落因为变异而失去产生红色素的能力时,也容易与木贼镰孢菌F.equiseti混淆。基于该组大孢子的典型特征,作者将锐顶镰孢菌F.acuminatum排除在该组之外。     

冠孢属一新种

采用EF-1α序列及气生菌丝上的孢子形态特征对九州镰孢菌、拟枝孢镰孢菌和厚垣镰孢菌的鉴定

对九州镰孢菌Fusarium kyushuense、厚垣镰孢菌F. chlamydosporum 和拟枝孢镰孢菌F. sporotrichioides在气生菌丝上产生的孢子进行了比较。九州镰孢菌在气生菌丝上产生多隔孢子（即中型分生孢子）;厚垣镰孢菌在气生菌丝上产生的主要是0隔针叶状分生孢子;拟枝孢镰孢菌在气生菌丝上产生两种类型的分生孢子：芜菁形、单胞分生孢子以及椭圆形、0－1隔的分生孢子。多隔的气生孢子（中型分生孢子）在厚垣镰孢菌和拟枝孢镰孢菌这两个种中偶尔可以观察到,但是不应作为对这两个种进行鉴定的主要     

神农架丝孢菌的研究——Ⅳ.尾孢菌属,短胖孢属和色链隔孢属(英文)

作者在前两篇文章里报道了湖北省神农架产的尾孢菌属及其近似属的22个种,本文再报道这一地区的尾孢菌属、短胖孢属及色链隔孢属的4个种,其中1个是新种,即李色链隔孢(Phaeoramularia pruni Guo et Liu,sp.nov.),其模式标本收藏于中国科学院真菌标本室(HMAS)。该新种与寄生于李属(Prunus sp.)植物上的变红尾孢(Cercospora rubrotincta)接近,但后者分生孢子梗窄(2—4.5μm),不分枝,曲膝状折点少(0—1个),分生孢子向顶渐狭,不链生,隔膜多(1—5隔),因此易于区别。

Seven species of Fainalges Gaud and Berla (Analgoidea, Xolalgidae) from Aratinga holochlora (Sclater) (Aves, Psittacidae)

The greatest number of feather mite Congeners occurring on a single host are members of the genus Fainalges Gaud & Berla (Acarina, Xolalgidae), associates of New World parrots. For the green conure, Aratinga holochlora (Sclater) (Aves, Psittacidae), there are six new and one previously known Fainalges species; these will be (re) described herein. The new species are: F. bilobatus, F. latistriatus, F. spiculatus, F. stettenheimi, F. tanythrix, F. vulgaris ; the redescribed species is F. longissimus Mejía-González & Pérez. Additionally, the developmental series for each species is (re)described. The microhabitats of the two most abundant species, F. bilobatus and F. vulgaris , are established. Fainalges brevissimus Mejía-González & Pérez is considered as a junior synonym of F. intermedius (Trouessart).     

A new species of Ferulago W. Koch (Umbelliferae) from north-west Turkey

Studies in African Cyperaceae 23. New taxa and combinations in Fimbristylis Vahl II

Two new subspecies, Fimbristylis miliacea (L.) Vahl ssp. pallescens Lye and F. miliacea (L.) Vahl ssp. macroglumis Lye, are described and illustrated from East Africa. In addition two new combinations are made, viz. F. complanata (Retzius) Link ssp. keniaeensis (Kükenthal) Lye and F. ferruginea (L.) Vahl ssp. sieberiana (Kunth) Lye.     

Two new Fagopyrum (Polygonaceae) species,F. gracilipedoides and F. jinshaense from Yunnan,China

Two new Fagopyrum (Polygonaceae) species, F. gracilipedoides and F. jinshaense, are described. Fagopyrum gracilipedoides was only found at Baoshan village, Lijiang district, Yunnan province, China. This species resembles the weedy species, F. gracilipes in morphology but they differ in both mating system and ploidy level; F. gracilipedoides is a heterostylous self-incompatible diploid species (2n = 16), whereas F. gracilipes is a self-compatible tetraploid species (2n = 32). Fagopyrum jinshaense was found along the Jinsha River valley near the border of Sichuan, Yunnan, and Tibet in China. Fagopyrum jinshaense is morphologically similar to F. gilesii, but they differ in the morphology of their inflorescences. Fagopyrum jinshaense has long spike-like inflorescences, whereas F. gilesii has a compact head-like one. Both F. jinshaense and F. gilesii are self-incompatible with heterostylous flowers and are diploid. Interspecific crosses between the two new species and already known species in the urophyllum group of Fagopyrum resulted in the production of self- and cross-sterile hybrids in the species combinations attempted. These results indicated that both new species are reproductively isolated from other Fagopyrum species. Molecular phylogenetic analysis based on the nucleotide sequence of the trnK gene intron in chloroplast DNA revealed the following points: 1) F. gracilipedoides, F. rubifolium and F. gracilipes / F. capillatum showed a trifurcating relationship and 2) F. jinshaense formed a clade with F. pleioramosum, F. callanthum, and F. macrocarpum, and was only distantly related to F. gilesii. In the clade of F. capillatum, F. gracilipes, F. gracilipedoides and F. rubifolium, the breakdown of self-incompatibility accompanying genome duplication seems to have occurred twice independently.     

Purification of the oligosaccharide-cleaving enzymes of Flavobacterium meningosepticum.

Four oligosaccharide chain-cleaving enzymes, including two new endoglycosidases distinct from endo-beta-acetylglucosaminidase (Endo) F1, have been identified and purified to homogeneity from cultural filtrates of Flavobacterium meningosepticum. FPLC-directed hydrophobic-interaction chromatography in conjunction with high-resolution ion-exchange chromatography provided a more simple, rapid method for the isolation of endoglycosidase F1, F2 and F3, and the amidase, peptide-N4-N-acetyl-beta-D-glucosaminyl)-asparagine amidase (PNGase F), in greater than 50% yield. The specificity of PNGase F and Endo F1 are well established. Endo F2 and Endo F3 represent new distinct endoglycosidases that prefer complex as compared to high-mannose asparagine-linked glycans. Endo F2 cleaved biantennary oligosaccharides, whereas Endo F3 cleaved both bi- and triantennary oligosaccharides.
