Two new Dematiaceous Hyphomycetes from humid tropic forest litter

Abstract

Two Dematiaceous Hyphomycetes, Beltraniella lyrata and Beltraniopsis fabularis, found on tropical forest litter in the Tai National Park in Ivory Coast are proposed as new species and described.     

Two new species of Spadicoides from Brunei and Hong Kong

Spadicoides hodgkissa sp. nov. and Spadicoides arengae sp. nov., recorded from submerged decaying wood in Hong Kong and from decaying palm fronds in Brunei, are described and illustrated. Spadicoides hodgkissa is characterized by versicolored, obovoid conidia with up to 2 septa, including a distal distoseptum and a proximal euseptum, while Spadicoides arengae is characterized by unicellular, ellipsoidal conidia with verruculose walls that are relatively large. Eight genera, including Dendrographium, Helminthosporium, Luzfridiella, Paliphora, Polyschema, Polytretophora, Porosubramaniania, and Weufia, have the same conidiogenesis as Spadicoides. A key to these genera is provided.     

Porobeltraniella gen. nov. to accommodate two species of Beltraniella

The genus Beltraniella Subramanian is characterized by setiform conidiophores with radially lobed basal cells, separating cells and lageniform conidia with the distal free end truncate, proximal end rostrate, with a subhyaline transverse band at equatorial zone. Beltraniella porosa and Beltraniella patilii are two species that show characteristics distinct from Beltraniella: They have sterile lateral setae arising at the conidiogenous apparatus and several equatorial pores in place of the continuous band. A new genus, Porobeltraniella, is described to accommodate them.     

Three new species of <Emphasis Type="Italic">Spadicoides</Emphasis> from Lushan Mountain,China

Spadicoides lushanensis sp. nov., S. multiseptata sp. nov. and S. rostrata sp. nov. are described and illustrated from specimens collected on dead branches of unidentified plants in Lushan Mountain, China. Spadicoides lushanensis is characterized by obclavate, rostrate, pale brown, 40–65?×?4.5–5.5 μm, smooth, 6–8-euseptate conidia. Spadicoides multiseptata is easily distinguished by obclavate, smooth, 11–15-euseptate, 65–115?×?11.5–13 μm, brown to pale brown conidia with a subacute apex. Spadicoides rostrata differs from other described Spadicoides species by obclavate, rostrate, pale brown, 40–65?×?10.5–12.5 μm, smooth, predominantly 5-euseptate conidia. A dichotomous key to Spadicoides species is provided.     

Spadicoides camelliae and Diplococcium livistonae, two new hyphomycetes on dead branches from Fujian Province, China

Two new dematiaceous hyphomycetes, Spadicoides camelliae and Diplococcium livistonae, are described and illustrated based on specimens collected from the subtropical forests in Fujian Province, southeast China. They were collected on dead branches of Camellia japonica and Livistona chinensis, respectively. Spadicoides camelliae is characterized by polytretic, terminal conidiogenous cells with solitary, ovoid, versicolored, and mainly 2-septate conidia (15.0–22.0 × 7.0–10.0 μm). Diplococcium livistonae is distinguished by polytretic, terminal, and intercalary conidiogenous cells with catenate, cylindrical, concolored, and mainly 2-septate conidia (15.0–28.0 × 5.0–7.0 μm). They are compared with other similar species by their morphological characteristics.     

LignicolousHyphomycetes from Czechoslovakia 6.Spadicoides andDiplococcium

Seventeen species belonging toSpadicoides Hughes andDiplococcium Grove collected in Central Europe mostly in Czechoslovakia are described and illustrated. Two new species are described inSpadicoides—S. carpatica Hol.-Jech.,S. penatium Hol.-Jech. and three new species inDiplococcium—D. bicolor Hol.-Jech.,D. insolitum Hol.-Jech. andD. parcum,Hol.-Jech.     

Purification and characterization of a new endo-1,4-beta-D-glucanase from Beltraniella portoricensis

A new endoglucanase, designated BCE1, produced by Beltraniella portoricensis, was purified from the culture supernatant. The N-terminal amino acid sequence suggests that BCE1 belongs to family 45 glycoside hydrolase (family 45 endoglucanase). The molecular mass of BCE1 was found to be 40 kDa by sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE). The optimum pH for the carboxymethyl cellulase (CMCase) activity of BCE1 was 4.5, and the optimum temperature was 55 degrees C. Among family 45 endoglucanases, RCE1 and RCE2 from Rhizopus oryzae, PCE1 from Phycomyces nitens, and EGL3 and EGL4 from Humicola grisea, BCE1 was most resistant to anionic surfactant and oxidizing agent. These results indicate that BCE1 might prove to be a useful enzyme in the detergent industry.     

广西金钟山鸟类保护区鸟类多样性初步研究

本文共记录到金钟山鸟类274种,分别隶属于18目57科,其中陆生鸟类251种,水鸟23种;以留鸟为主,共157种;候鸟、旅鸟分别为104种、13种;东洋种为优势类群,共有171种,古北种和广布种分别为4种、27种。这些鸟类中有国家重点保护鸟类39种,中国特有种鸟类3种,列入世界自然保护联盟红皮书名录中的鸟类5种,列入中国濒危动物红皮书名录中的鸟类20种,列入CITES附录中的鸟类34种。本文还对金钟山鸟类保护区的5种不同生境类型的鸟类种类组成作了比较,结果表明灌丛＋农田的鸟种多样性指数最高,为3．04;水域的鸟种多样性指数最低,为2．14。
