马鞍菌属3个中国新记录

【背景】目前国内学者已发表60个马鞍菌属物种,但山西省尚缺乏马鞍菌属真菌分布的系统性报道。【目的】调查我国山西省马鞍菌属的种类组成及地理分布。【方法】采集标本,对其进行详细的形态特征描述,并提取DNA,测定热激蛋白(heat shock protein, hsp)和核糖体大亚基(large subunit, LSU)序列,基于贝叶斯法(Bayesian inference, BI)和最大似然法(maximum likelihood, ML)构建分子系统发育树。【结果】鉴定结果表明这3个马鞍菌属物种分别为类帽状马鞍菌(Helvella capucinoides)、丹麦马鞍菌(H. danica)和柔毛马鞍菌(H. pubescens)。它们在形态上与模式标本的描述基本一致。基于hsp和LSU的系统发育关系分析也支持形态学的鉴定结果。【结论】参考我国截至目前已报道的马鞍菌属物种,确定这3个种均为中国新记录种。

Minidiscus,a New Recorded Nanodiatom Genus for China

Minidiscus trioculatus, M. comicus and M. chilensis are new records for China, and M. subtilis, is a new species. They differ from Thalassiosira species by their strutted processes and one single labiate process being distant from valve margin and they differ from each other by their areola patterns on valves and distribution patterns of strutted processes and the labiate process. A key to the species of Minidiscus is given. Minidiscus subtilis Gao, Cheng et Chin sp. nov., figs 7-8 Valves disc-shaped, slightly concave in center, weakly silicified, 3.5-5.5μm in diameter. Areola unequally radiate-striate, striae 8.5 / lμm. A narrow valve mantle without striae. Three strutted processes and a single labiate process located in the central area of the valve. Among them, one strutted process in the very center with the other two adjacent to it, forming an isometric triangle with the labiate process between the two subcentral strutted processes. Two small satellite pores in each base of the strutted processes. M. subtilis differs from M. chilensis mainly by their radiate striae continuously distributed from the valve center tothe margin.     

Shaniodendron,a New Genus of Hamamelidaceae from China

During investigating rare and endangered plants in China, the authors made morphological observation on Hamamelis subaequalis H. T. Chang and discovered that it is apetalus, different from the tribe Hamamelideae, in addition to other morphological characters, which differ from the genera of the tribes Distylteae and Fothergilleae(Hamamelidaceae). Therefore, a new genus-Shaniodendron is described.     

Pyrgophyllum,a New Genus of Zingiberaceae from China

Pyrgophyllum (Gagnep.) T. L. Wu et Z. Y. Chen is a monotypic genus of Zingiberaceae from China. Originally, it was placed in Kaempferia as a subgenus by Gagnepain (1901), later transferred to Camptandra by Schumann (1904) and to Caulokaempferia by R. M. Smith. (1972). In this paper, the authors suggest that the separation of Pyrgophyllum at generic rank is justified on cytological, morphological and anatomical evidence. It is characterised by the large lamina-like bracts, which are rarely seen in Zingiberaceae. The margin of each bract is adnate to the main axis of the inflorescence at the base and the lip is lobed. Trichomes unicellular, stomata each with 4-7 lateral subsidiary cells, lateral veins are of three various types of vascular bundles: girder-shaped, semigirder-shaped and isolated. The pollen grains are spinecent. The basic chromosome number (x) is 21. The type species, Pyrgophyllum yunnanensis (Gagnep.) T. L. Wu et Z. Y. Chen (Kaempferia yunnanensis Gagnep.), is only distributed in Yunnan and Sichuan provinces of China.
