中国粘菌Ⅷ.中国新纪录属贫丝菌属Oligonema及其新种:膨丝贫丝菌O.oedonema

贫丝菌属Oligonema是由Rostafinski在1875年建立的,至今仅承认4个种,中国前此尚无记载。作者在长白山采到的这份标本,孢丝极少且短小,中部膨肿,有不甚清晰的螺纹带,具贫丝菌的特征,与已知的种明显不同,因此确认为本属的新成员,定名为膨丝贫丝菌O. oedonema,主模式保存在中国科学院微生物研究所真菌标本室。     

中国灵芝属一新种和一新记录

本文描述了灵芝属一新种:兼性灵芝Ganoderma bicharacteristicum X.Q. Zhang,和一个新记录种:奇异灵芝Ganoderma mirabile(Lloyd) Humphrey.作者为新种提供了拉丁文特征提要及英文描述。上述两种所引证的标本保藏在中国科学院微生物研究所真菌标本室(HMAS)。     

Seven new calochroid and fulvoid species of Cortinarius

We describe seven new European species of Cortinarius. All species are based on analyses of morphological and DNA sequence data. They all belong to a well-supported clade comprising most species traditionally treated in Cortinarius subgenus Phlegmacium sections Fulvi and Calochroi (i.e. the/Calochroi clade). All taxa are either fulvoid (containing anthraquinoid pigments) or calochroid (without these pigments). Morphological and ecological data are presented for all species and compared with similar species. A dichotomous key is presented for C. calochrous and similar species, including all six newly described calochroid species. The calochroid species C. albertii, C. chailluzii, C. cisticola, C. sancti-felicis, C. selandicus and C. vesterholtii spp. nov., and the fulvoid species C. langeorum sp. nov. are described.     

Taxonomic notes on Pogonieae ( Orchidaceae ): Cleistesiopsis, a new genus segregated from Cleistes , and description of two new South American species, Cleistes batistana and C. elongata

Summary  A new genus, Cleistesiopsis, was segregated from Cleistes based on morphological and molecular characteristics, and two new species of Cleistes: C. batistana and C. elongata, both occurring in the Brazilian Central Plateau (Central-Western Brazil), are described and illustrated. Furthermore, a key to genera currently recognised within Pogonieae is presented.

Resumo  Um novo gênero, Cleistesiopsis, é segregado de Cleistes com base em caracteres morfológicos e moleculares, e duas novas espécies de Cleistes: C. batistana e C. elongata, que ocorrem no Planalto Central, no Centro-Oeste do Brasil, s?o descritas e ilustradas. Além disso, uma chave para os gêneros que atualmente comp?em a tribo Pogonieae é apresentada.

     

Novel hosts of the Eucalyptus canker pathogen Chrysoporthe cubensis and a new Chrysoporthe species from Colombia

The pathogen Chrysoporthe cubensis (formerly Cryphonectria cubensis) is best known for the important canker disease that it causes on Eucalyptus species. This fungus is also a pathogen of Syzygium aromaticum (clove), which is native to Indonesia, and like Eucalyptus, is a member of Myrtaceae. Furthermore, C. cubensis has been found on Miconia spp. native to South America and residing in Melastomataceae. Recent surveys have yielded C. cubensis isolates from new hosts, characterized in this study based on DNA sequences for the ITS and β-tubulin gene regions. These hosts include native Clidemia sericea and Rhynchanthera mexicana (Melastomataceae) in Mexico, and non-native Lagerstroemia indica (Pride of India, Lythraceae) in Cuba. Isolates from these hosts and areas group in the sub-clade of C. cubensis accommodating the South American collections of the fungus. This sub-clade also includes isolates recently collected from Eucalyptus in Cuba, which are used to epitypify C. cubensis. New host records from Southeast Asia include exotic Tibouchina urvilleana from Singapore and Thailand and native Melastoma malabathricum (Melastomataceae) in Sumatra, Indonesia. Consistent with their areas of occurrence isolates from the latter collections group in the Asian sub-clade of C. cubensis. DNA sequence comparisons of isolates from Tibouchina lepidota in Colombia revealed that they represent a new sub-clade within the greater Chrysoporthe clade. Isolates in this clade are described as Chrysoporthe inopina sp. nov., based on distinctive morphological differences.
