Morphological and phylogenetic analyses reveal eight novel species of (Sporocadaceae, Amphisphaeriales) from southern China.

Plants play an important role in maintaining the ecological balance of the biosphere, but often suffer from pathogenic fungi during growth. During our continuing mycological surveys of plant pathogens from terrestrial plants in Jiangxi and Yunnan provinces, China, 24 strains of isolated from diseased and healthy tissues of plant leaves represented eight new species, viz. , , , , , , and .

Multi-locus phylogenetic analyses reveal eight novel species of from southern China.

Members of this genus occur mainly as asexual morphs, forming effuse, hairy colonies on decaying wood, plant stems, bamboo culms, and fallen leaves and shafts in terrestrial and freshwater habitats. In the present study, saprobic hyphomycetes from plant debris were investigated, and eight new species were introduced based on morphology and phylogenetic analyses of LSU, ITS, , and sequence data.

Keqinzhangia aquatica gen. et sp. nov. and Pseudocoronospora hainanense gen. et sp. nov., isolated from freshwater in southern China.

During an investigation of the diversity of aquatic hyphomycetes from southern China, two interesting isolates were collected. These two isolates were cultured and sequenced, and a BLAST search of their LSU sequences against data in GenBank revealed that the closest related taxa were in the genus Microthyrium. Phylogenetic analyses, based on the combined sequence data from the internal transcribed spacer (ITS) and large nuclear subunit ribosomal DNA (LSU), revealed that our isolates belong to the Microthyriaceae.

Two new asexual genera and six new asexual species in the family Microthyriaceae (Dothideomycetes, Ascomycota) from China.

The family Microthyriaceae is represented by relatively few mycelial cultures and DNA sequences; as a result, the taxonomy and classification of this group of organisms remain poorly understood. During the investigation of the diversity of aquatic hyphomycetes from southern China, several isolates were collected. These isolates were cultured and sequenced and a BLAST search of its LSU sequences against data in GenBank revealed that the closest related taxa are in the genus .

sp. nov., a -like fungus from North America.

Two isolates from Canada and the USA (UAMH 7122 and UAMH 7211, respectively) previously identified as were studied by morphology and six-locus phylogeny (, ITS, , , and ). UAMH 7122 and UAMH 7211 are morphologically related but phylogenetically distinct from (≡) and . Hence, UAMH 7122 and UAMH 7211 are described as a new species, sp.

(Chaetosphaeriaceae, Sordariomycetes), a novel asexual genus and species from freshwater in southern China.

The asexual taxon , collected from submerged dicotyledonous leaves in Hainan, China, is described and illustrated herein. is characterized by macronematous, semimacronematous, septate and pigmented conidiophores and acrogenous, long lunate, vermiform to sigmoid, hyaline conidia with an eccentric basal appendage. Complete sequences of internal transcribed spacer (ITS) and partial sequences of nuclear large subunits ribosomal DNA (LSU) genes are provided.

sp. nov., a novel species of endophytic fungus from .

During a survey of endophytic fungi in aquatic plants collected from Tibet, PR China, a novel species, was isolated from . This novel species differs from other species of the genus by its finely verrucose, obovoid, ellipsoidal-obovoid and occasionally subglobose conidia. Phylogenetic analysis of the combined sequences of the internal transcribed spacers (ITS) and the translation elongation factor 1-alpha gene () confirmed that the isolated strain represents a member of the genus .

Comparison of aquatic hyphomycetes communities between lotic and lentic environments in the Atlantic rain forest of Pernambuco, Northeast Brazil.

Riparian forests are important to aquatic ecosystems and produce large quantities of organic matter that are recycled by the microbial community that includes microscopic fungi. The aim of this study was to unveil and compare the diversity of aquatic hyphomycetes associated to submerged leaf litter of tropical lotic and lentic environments in the Atlantic Forest of Northeast Brazil. Six sampling events were carried out in six points of two study areas: Biological Reserve "Mata da Chuva" (MC) and Environmental Protection Area "Lagoa da Mata" (LM), in Pernambuco, Brazil.

gen. et sp. nov., a new helotialean fungus.

A new genus and species, , is described and illustrated from leaves of mildewed tobacco. It is characterised by branched, septate hyphae from which arise macronematous, unbranched or spaced branched conidiophores and mono- or polyblastic conidiogenous cells that produced solitary and blastocatenate, obovoid, oblong, ellipsoidal, allantoid, broad fusiform to irregular, unicellular, hyaline conidia. The phylogenetic analyses, based on the combined sequence data from the small and large nuclear subunit ribosomal DNA (SSU and LSU), placed in the Leotiomycetes class, Helotiales order.
