中国甘肃省狭义丝盖伞属二新种

依据形态学和分子系统学研究结果,描述了产自中国甘肃省的狭义丝盖伞属2个新种,即拟黄囊丝盖伞Inocybe muricellatoides和甘肃丝盖伞I. gansuensis。对新种的ITS、LSU和rpb2片段进行了测序和分析,并提供了详细描述、线条图、生态照片及与相似种的区别。拟黄囊丝盖伞以菌盖翘起的鳞片、菌柄纤维状、孢子光滑和厚壁的侧生囊状体为主要识别特征。甘肃丝盖伞具有粗壮的子实体、较大的孢子和厚壁侧生囊状体。基于LSU和rpb2联合数据的分子系统发育分析显示这两个新种隶属于狭义丝盖伞属且分别占据独特的分支。

Some New Taxa of Nitella from Guangdong,China

Guangdong Province extends across the subtropical and tropical zones. With favorable climate and plentiful rainfall, this district is extremely rich in plants. However, the study on the Charophyta in this province is scanty. The specimens we identified were collected from 4 cities and 10 counties of the province. The result shows that there are abundant representatives of Chrophyta, especially in Nitella, in the province. In this paper, however, only reported are some new taxa of Nitella. The 2 new species are Nitella sessilis and N. guangdongensis; the 3 new varieties are Nitella flagelliformis var. conglomerata, N. brevidactyla var. hainanensis and N. pakistanica var. magniantheridii; and the 3 new records of distribution in China are Nitella bengalensis Kundu, N. madagascariensis Zanev. and N. tenuissima var. sanukensis Imah.

Some New Taxa and New Records of Scenedesmus from China

Anhui Province is situated in the subtropical and temperate zones. With favorable climate this district is rich in algae. During 1982-1986, the author made a number of collections of the algal specimens-about 1000 samples from 36 counties and cities of the province. The identification result shows that there are about 30 species and 15 varieties of Scenedesmus in the province. In present paper, however, reported are only some new taxa and new records of Scenedesmus. The 4 new species are Scenedesmus anhuiensis, S. huangshanensis, S. quadrialatus and S. wuhuensis, the 2 new varieties are Scenedesmus prismaticus var. spinosus and S. smithii var. spinulosus, and the 4 new records of distribution in China are Scenedesmus denticulatus var. australis Playfair, S. prismaticus Bruhl et Biswas, S. quadricauda var. dentatus Dedussand S. smithii Teiling.     

New Late Miocene murids from China (Mammalia, Rodentia)

New murids of Late Miocene (medial Baodean Chinese Mammal Unit) age from Inner Mongolia, northern China, and from Yunnan Province, southern China, are described. Hansdebruijnia perpusilla nov. sp. represents the earliest known and morphologically most primitive species of the genus, which is known from the latest Miocene of Europe and western Asia. The new species suggests an eastern Palaearctic origin of Hansdebruijnia. “Progonomys” yunnanensisQIU and STORCH, 1990 from Lufeng, Yunnan Province, is referred to Linomys nov. gen. New samples from Leilao, Yuanmou County, Yunnan Province, are included in this species, although this population is somewhat more primitive than that from Lufeng. Leilaomys zhudingi nov. gen. and sp. from Leilao shows a unique combination of apomorphic and plesiomorphic characters, which suggest an early divergence from the murid stem. The new findings indicate that our knowledge of the early radiation of murids in southeast Asia is still in its infancy.     

New Taxa of Festuca L. from China

Some new taxa of the genus Festuca (Gramineae) are described from China. They are Sect. Longiglumes S.L. Lu,Sect. Muticae S.L. Lu, Sect. Sinensis S.L. Lu, Sect, Nitidulae S.L. Lu, and Festuca pubiglumis S.L. Lu, F. longiglumis S. L. Lu, F.fascinata Keng, F. mutica S.L. Lu, F. sinensis Keng, F. subalpina Chang et Skvort. ex S.L.
