Three new species of Chaetomium from soil

Chaetomium macrostiolatum sp. nov., Chaetomium olivicolor sp. nov. and Chaetomium tarraconensis sp. nov. isolated from Nigerian, Indian, and Spanish soils respectively, are described and illustrated. The first species is characterized by ascomata with a very broad ostiole and yellow hairs, and limoniform ascospores; the second by its thermotolerant growth, inconspicuous and short straight ascomatal hairs and fusiform ascospores; and the last by its unusual, irregularly-shaped ascospores and subglobose ascomata with flexuous to undulate, unbranched ascomatal hairs.     

Three new species ofPenicillium isolated from soil

Three new species ofPenicillium Linkex Gray nom. cons. prop. are described and illustrated. These species have been recovered from samples of sandy soil under pine trees. They differ from all species of theGenus described so far and are, therefore, considered and proposed as new taxa:Penicillium rubefaciens sp. nov.,Penicillium vaccaeorum sp. nov. andPenicillium michaelis sp. nov.

A new species from tropical soils,Eupenicillium tropicum

Forty-three strains of Eupenicillium tropicum sp. nov. were isolated from soils collected in India, Costa Rica and Galapagos, Ecuador. The species is characterized by biverticillate penicilli, slightly rough, subglobose to ovate conidia, brownish cleistothecia that become brown-gray with age, and ascospores with two equatorial flanges and slightly roughened valves. All strains produced a large number of indole alkaloids, and many types of unknown secondary metabolites with characteristic chromophores were produced by a majority of strains. Eupenicillium tropicum is morphologically most similar to E. shearii, but based on ITS-LSU sequences, is most closely related to Penicillium citrinum, P. sartoryi and P. westlingii. Eupenicillium shearii strains consistently produce paxillin, paspalinine and shearinins, while the latter three penicillia all produce citrinin consistently.     

Eupenicillium bovifimosum, a new species from dry cow manure in Wyoming

A new species, Eupenicillium bovifimosum, was isolated from dry cow manure collected in Wyoming, USA. The outstanding morphological characteristics of this species are its robust, dense penicilli bearing long, broad columns of conidia, and its smooth-walled, unflanged ascospores which are produced within 3 wk of inoculation onto MEA. The new species produces penicillic acid, a fumagillin-like molecule, patulodin-like compounds CK2108A and CK2108B, and a compound resembling 2-[(2-hydroxypropionyl)amino]benzamide. Phylogenetic analysis using 1100 bases of the ITS and LSU DNA regions indicates that E. bovifimosum is most closely related to E. baarnense, and also to E. crustaceum, E. egyptiacum, and E. tularense.     

Three new species and a new combination in the genusTorulomyces from soil

Seven isolates ofTorulomyces from Asian and Australian soil samples were studied in comparison with known taxa of the genus and withMonocillium indicum, the type species ofMonocillium. Three new species,Torulomyces parviverrucosus, T. laevis, andT. ovatus, are described, andT. brunneus is described as a new combination. Conidial characteristics, especially their shape and surface structure, are useful taxonomic criteria for distinguishing species ofTorulomyces. Monocillium is considered to be a distinct genus.     

中国西藏土壤中节格孢属真菌的三个新种

从中国西藏土壤中分离到3种节格孢属Scytalidium真菌,据形态学特征和分子系统学分析,他们不属于该属中任何已知种,遂在本文中作为新种加以描述和发表,它们是：具有多纵隔膜的中国节格孢S. chinense、能产红色色素的西藏节格孢S. tibetense和孢子与菌丝均具瘤突的具瘤节格孢S. tuberculatum。新种的模式标本（干制培养物）分别保藏在山东农业大学植物病理学标本室（HSAUP）和中国科学院菌物标本馆（HMAS）。     

A new species ofScopulariopsis from soil

A new species ofScopularoipsis described from soil is characterized by the conidiophores, branches, and sporogenous cells being distinctly swollen. The conidia have a well-marked germ slit running more or less longitudinally down the spore. TheScopulariopsis state ofMicroascus doguetii is re-examined and evidence is presented which indicates that the striations on the walls of the spores are germ slits.     

A new species ofConiochaetidium from soil

A new species ofConiochaetidium isolated from soil of Iraq is described. The speciesC. nuciforme differs fromC. savoryi in the shape and size of the ascospores. A key to differentiate the accepted species of the genus is reported.     

Three new species of Rubus from Spain

Three new species of Rubus subgenus Rubus series Pallidi from Spain are described, mapped and illustrated: R. Cyclops, R. castroviejoi and R. urbionicus.     

泰国胡椒科胡椒属三新种

The genus Piper L. is estimated to contain over 1000 species which are distributed mainly in tropical regions of the world. Several species have great economic and cultural importance and are used as foods, medicines, stimulants, antiseptics and antioxidants. Moreover, their essential oil and leaf extracts possess activities against several bacterium strains and fungi. Leaves of P. hispidinervum C. DC. contain a high level of safrole (83%–93%) which is an important raw material for chemical…     

Three new species of Bromeliaceae from Ecuador

Three new species of Bromeliaceae (subfamily Tillandsioideae) from Ecuador are described and illustrated: Guzmania atrocastanea from Prov. Morona-Santiago; G. condorensis from Prov. Zamora-Chinchipe; and Vriesea boeghii from Prov. Loja.     

Three new species of Acanthaceae from Ethiopia

Summary  Three new species of Acanthaceae, Lepidagathis pseudoaristata Ensermu, Acanthopale aethio-germanica Ensermu, and Rhinacanthus mucronatus Ensermu, are described from Ethiopia. The three species are illustrated and their distributions mapped. The three new species are also compared to their presumed closest relatives. L. pseudoaristata is restricted to the Bale and Sidamo Regions, A. aethio-germanica is more widely distributed in Ethiopia occurring in the Kefa, Arsi, Sidamo and Bale Regions, and R. mucronatus is a local endemic restricted to the Borana area in the Sidamo Region. The conservation status of each species is also assessed.
