Investigation of various cheese rinds for Bisifusarium domesticum revealed a completely unexpected diversity of Fusarium-like fungi. Elongation factor 1-alpha gene sequence data, classically used for Fusarium spp. identification, suggested that some isolates corresponded to so far undescribed Nectriaceae species. In this context, a multi-gene phylogenetic analysis, based on ten loci, namely the large subunit of the ATP citrate lyase (acl1), alpha-actin (act), calmodulin (cmdA), histone H3 (his3), the internal transcribed spacer region and intervening 5.8S nrRNA (ITS), 28S large subunit (LSU), RNA polymerase II largest subunit (rpb1), RNA polymerase II second largest subunit (rpb2), translation elongation factor 1-alpha (tef1) and β-tubulin (tub2), was therefore performed to determine the phylogenetic position of ten cheese and one environmental isolates. Phylogenetic reconstructions were then done using a Nectriaceae sequence dataset. Additionally, morphological observations as well as metabolite profiling were performed. Results clearly revealed the existence of four novel cheese-associated species, namely Bisifusarium allantoides, Bisifusarium penicilloides, Longinectria lagenoides, Longinectria verticilliforme, the two latter belonging to a novel genus (Longinectria gen. nov.).

Camellia sinensis, commonly known as tea, is one of the most economically important crops in China. Shoot and leaf necrosis in tea is of considerable concern as it directly affects the quality and quantity of tea leaf harvest. In the present study, diseased leaves and shoots were collected from Fujian Province to identify the fungal species associated with the disease. In total 110 strains were isolated and they were identified by morphological characteristics and multi-locus phylogenetic approaches. Thirty–two species belonging to 13 genera and 11 families associated with shoot and leaf necrosis of tea were identified. Five new species; Chaetomium camelliae, Diaporthe fujianensis, D. fusiformis, D. sinensis and Trichoderma camelliae are introduced. In addition, nine novel host records are reported. These results indicate high species richness on tea leaves and shoots. In addition, a checklist for fungi associated with C. sinensis worldwide is provided. Information presented in this study provides new insights into fungi associated with leaf necrosis and shoot blight of C. sinensis in China. However, further studies are necessary to understand the pathogenic potential and biocontrol ability of the species identified in this study.

Cytospora species are important pathogens, which have a worldwide distribution, broad host range and are commonly associated with tree dieback and canker disease. Lack of ex-type cultures or inability to link multi-gene DNA sequence data in GenBank to phylogenetic analyses makes it difficult to classify Cytospora taxa to species level. In this study, ten specimens of Cytospora were collected from dead wood in China, Italy and Thailand. Based on their morphology and phylogenetic characterization, four new species (C. diopuiensis, C. galegicola, C. pingbianensis and C. pubescentis) and four known species (C. cedri, C. cotini, C. predappioensis and C. prunicola) are herein described, illustrated and compared with related taxa. Detailed morphological descriptions of the holomorph (C. galegicola, C. prunicola, C. predappioensis and C. pubescentis), the sexual morph (C. cedri, C. cotini, C. diopuiensis and C. pingbianensis) and a new record of C. predappioensis in China are provided. Phylogenetic analyses of a combined ITS, LSU, ACT and RPB2 DNA sequence dataset support their placement in the genus Cytospora and justify the new species and identification of known species.

Pleosporales is the largest order in the class Dothideomycetes, comprising a quarter of all species of Dothideomycetes. This paper provides comprehensive illustrations and descriptions of newly collected saprobic pleosporalean taxa from dicotyledons and grasses in China, Italy, Russia and Thailand. These species are accommodated in 8 families in Pleosporales. The taxa described here include 14 new species, a new geographical record and three new host records of known species. New species are Alternaria rumicis, Bambusicola ficuum, Comoclathris flammulae, C. europaeae, C. lonicerae, Ophiobolus lathyri, Paraophiobolus torilicola, Parastagonospora dactylidicola, P. hieracioidis, Pseudopaucispora hyalinospora, Stagonospora poaceicola, Stemphylium artemisiae and Subplenodomus meldolanus. All species descriptions presented herein are based on morphological comparisons coupled with multi-gene phylogenetic analyses.

Phyllosticta species have worldwide distribution and are pathogens, endophytes, and saprobes. Taxa have also been isolated from leaf spots and black spots of fruits. Taxonomic identification of Phyllosticta species is challenging due to overlapping morphological traits and host associations. Herein, we have assembled a comprehensive dataset and reconstructed a phylogenetic tree. We introduce six species complexes of Phyllosticta to aid the future resolution of species. We also introduce a new species, Phyllosticta rhizophorae isolated from spotted leaves of Rhizophora stylosa in mangrove forests of Taiwan. Phylogenetic analysis based on combined sequence data of ITS, LSU, ef1α, actin and gapdh loci coupled with morphological evidence support the establishment of the new species. We synonymize strains of P. capitalensis (CPC 20508 and CPC20509) under the new species. Six strains (CBS 173.77, CBS 119720, CPC 17748, CPC 20252, CPC 20269, and CBS 123404) are unnamed species based on phylogenetic analyses and nucleotide polymorphisms and probably represent new species. The phylogenetic relationships of Phyllosticta species are reappraised and suggestions are given for future work.
