Morphological Studies of Rhaphidopteris hsüi sp. nov

The present paper deals with the cuticular structure of Rhaphidopteris hsüi sp. nov. The specimens were collected from the Upper Triassic cos series of Liuzhi district, Guizhou Province. Based on the shape and cuticular structure of leaf and segments, this new species is assigned to Corystospermaceae of Cycadofilicales. According to the assemblage of the fossil plants, the writers consider that the geological age of this flora is assigned to the middle Keuper-Rhaetic stage of Late Triassic.     

The first isolation of ustilaginomycetous anamorphic yeasts,Pseudozyma species,from patients' blood and a description of two new species: P. parantarctica and P. thailandica

The genus Pseudozyma is ustilaginomycetous anamorphic yeasts, and are mainly isolated from plants. We isolated three Pseudozyma strains from the blood of patients in Thailand. While one isolate was identified as P. antarctica by rDNA sequence analysis, the other two were considered to be new species and were named P. parantarctica and P. thailandica. The three isolates proved to be resistant to 5-flucytosine, and P. thailandica was also resistant to fluconazole and itraconazole. As far as we know, this is the first isolation of Pseudozyma strains from humans. The two new species are described.

中国松塔牛肝菌属新种和新记录种

本文报道松塔牛肝菌属四个新种,即:裸皱松塔牛肝菌Strobilomyces gla-bellus Ying sp.nov.,阔裂松塔牛肝菌S.latirimosus Ying sp.nov.,微茸松塔牛肝菌S.subnudus Ying sp.nov.,短绒松塔牛肝菌S.velutinus Ying sp.nov.;及四个中国新记录种,即:柔鳞松塔牛肝菌S.mollis Corner,疣鳞松塔牛肝菌S.nigricans Berk.,锥鳞松塔牛肝菌S.polypyramis Hook.,半裸松塔牛肝菌S.semi-nudus Hongo.松塔牛肝菌属Strobilomyces以其具有变黑的担子果与菌幕、不粘的菌盖上有疣状、绵绒状或刺状鳞片以及黑褐色带明显纹饰的孢子而易于识别。Singer(1945)按孢子纹饰的不同将松塔牛肝菌属分为两个组,其一为具疣、刺和网纹的种类;另一为具纵贯孢子两端的翼状棱纹的种类。对于后者的归属问题,Pegler & Young持不同见解,并于1981建立了非洲牛肝菌属AfroboletusPegler & Young以纳孢子具翼状纵棱和孢缘边(rim)的种类;含2—4种,分布在非洲近赤道的地区。在中国,松塔牛肝菌属已报道过三个种,即:松塔牛肝菌Strobilomyces,floc-copus(Vahl.ex Fr.)Karst.光头松塔牛肝菌S.glabriceps Chiu和混淆松塔牛肝菌S.confusus Sing.。裘维蕃(1948,1957)曾描述过网孢松塔牛肝菌Strobi-lomyces retisporus(Pat.et Bak.)Gilb.但因其子实体色鲜红至褐红而不变黑色、子层体淡暗黄色且菌肉不变红-黑色、孢子具网纹而宜转隶于Heimiellia Boedijn(1951)。文中有新分类单位和国内已知种的分种检索表、新种的拉丁文和英文描述并有绘图和扫描电镜照片示明孢子纹饰。

Neokomagataea gen. nov., with Descriptions of Neokomagataea thailandica sp. nov. and Neokomagataea tanensis sp. nov., Osmotolerant Acetic Acid Bacteria of the α-Proteobacteria

Isolates AH11^T and AH13^T were isolated from flowers of lantana and candle bush respectively collected in Thailand. In phylogenetic trees based on 16S rRNA gene sequences, the two isolates formed an independent cluster, which was then connected to the type strain of Saccharibacter floricola. The calculated pair-wise 16S rRNA gene sequence similarities of isolate AH11^T were 95.7–92.3% to the type strains of the type species of the 12 genera of acetic acid bacteria. The DNA base composition was from 51.2 to 56.8 mol % G+C, with a range of 5.6 mol %. When isolate AH11^T was labeled, DNA-DNA similarities were 100, 12, 4, 5, and 4% respectively to isolates AH11^T and AH13^T and the type strains of Saccharibacter floricola, Gluconobacter oxydans, and Acetobacter aceti. The two isolates were non-motile and did not oxidize either acetate or lactate. No growth was found in the presence of 0.35% acetic acid w/v. The two isolates were not osmophilic but osmotolerant, produced 2,5-diketo-D-gluconate from D-glucose, and did not oxidize lactate, thus differing from strains of Saccharibacter floricola, which showed weak lactate oxidation. The two isolates contained unsaturated C_18:1ω7c fatty acid as the major fatty acid, and were unique in the presence of a considerable amount of straight-chain C_18:12OH fatty acid. Q-10 was present as the major isoprenoid quinone. Neokomagataea gen. nov. was proposed with the two species, Neokomagataea thailandica sp. nov. for isolate AH11^T (=BCC 25710 ^T =NBRC 106555^T), which has 56.8 mol % G+C, and Neokomagataea tanensis sp. nov. for isolate AH13^T (=BCC 25711^T=NBRC 106556^T), which has 51.2 mol % G+C.     

海拉尔盆地早白垩世蕉带羽叶属一新种

蕉带羽叶属一新种(Nilssoniopteris hailarensis sp.nov.)化石采于内蒙古自治区海拉尔盆地的一个钻孔中(北纬47°58′,东经117°10′)。其层位属于下白垩统伊敏组。该种以其全缘的窄线形长叶为特征。叶片及脉序为带羊齿型,表皮构造为本内苏铁型。叶片着生于中脉上表面的两侧。中脉在下表面宽约3mm,但在上表面露出的宽度仅有下表面宽度的1/3。被报道的种在叶形方面与西欧威尔登植物群的 Nilssonioptetis beyrichii(Schenk)典型标本较为接近,但两者的角质层特征有明显区别。对此本文作了较详细讨论。
