A survey of bambusicolous fungi in Bijiashan Mountain Park, Shenzhen, Guangdong Province, China, revealed several Arthrinium-like taxa from dead sheaths, twigs, and clumps of Bambusa species. Phylogenetic relationships were investigated based on morphology and combined analyses of the internal transcribed spacer region (ITS), large subunit nuclear ribosomal DNA (LSU), beta tubulin (β-tubulin), and translation elongation factor 1-alpha (tef 1-α) gene sequences. Based on morphological characteristics and phylogenetic data, Arthrinium acutiapicum sp. nov. and Arthrinium pseudorasikravindrae sp. nov. are introduced herein with descriptions and illustrations. Additionally, two new locality records of Arthrinium bambusae and Arthrinium guizhouense are described and illustrated.

Abstract Absidia is ubiquitous and plays an important role in medicine and biotechnology. In the present study, nine new species were described from China in the genus Absidia, i.e. A. ampullacea, A. brunnea, A. chinensis, A. cinerea, A. digitata, A. oblongispora, A. sympodialis, A. varians, and A. virescens. Besides, two varieties A. cylindrospora var. nigra and A. spinosa var. biappendiculata were elevated to a specific rank as A. nigra comb. nov. and A. biappendiculata comb. nov., respectively. These new taxa were proposed based on a comprehensive investigation of morphological traits (such as shape and size of sporangia, sporangiospores and projections on columellae), physiological feature (maximum growth temperatures), and multi-locus sequences (including internal transcribed spacer, large subunit D1-D2 domains of nuclear ribosomal DNA, partial translation elongation factor 1 alpha gene and actin gene). All species mentioned above are illustrated, and an identification key to all the known species of Absidia in China is included.

Three New Species

The taxonomy of Oculimacula, Rhynchosporium and Spermospora is re-evaluated, along with that of phylogenetically related genera. Isolates are identified using comparisons of DNA sequences of the internal transcribed spacer ribosomal RNA locus (ITS), partial translation elongation factor 1-alpha (tef1), actin (act), DNA-directed RNA polymerase II largest (rpb1) and second largest subunit (rpb2) genes, and the nuclear ribosomal large subunit (LSU), combined with their morphological characteristics. Oculimacula is restricted to two species, O. acuformis and O. yallundae, with O. aestiva placed in Cyphellophora, and O. anguioides accommodated in a new genus, Helgardiomyces. Rhynchosporium s. str. is restricted to species with 1-septate conidia and hooked apical beaks, while Rhynchobrunnera is introduced for species with 1–3-septate, straight conidia, lacking any apical beak. Rhynchosporium graminicola is proposed to replace the name R. commune applied to the barley scald pathogen based on nomenclatural priority. Spermospora is shown to be paraphyletic, representing Spermospora (type: S. subulata), with three new species, S. arrhenatheri, S. loliiphila and S. zeae, and Neospermospora gen. nov. (type: N. avenae). Ypsilina (type: Y. graminea), is shown to be monophyletic, but appears to be of minor importance on cereals. Finally, Vanderaaea gen. nov. (type: V. ammophilae), is introduced as a new coelomycetous fungus occurring on dead leaves of Ammophila arenaria.

A New Species

A new species, Cantharellus albus, was collected from southwestern China and described with both morphological and molecular characters. It differs from other species of Cantharellus by its smooth white pileus, white hymenophore, and white stipe, the latter turning yellow after bruising. The phylogenetic tree inferred from the combined dataset of three DNA fragments, namely large subunit ribosomal RNA gene (LSU), RNA polymerase II second largest subunit (rpb2), and translation elongation factor 1-alpha gene (tef1), indicated that the new species is distinct from other species of Cantharellus and is a member of sect. Flavobrunnei within the subgenus Parvocantharellus.

Abstract A novel species of Morosphaeria, Morosphaeria muthupetensis, saprobic on intertidal mangrove wood of Rhizophora mucronata from Muthupet mangroves on Kaveri River Delta, Tamil Nadu along the East coast of India, is described in this paper. Morosphaeria muthupetensis is characterized by large sub-globose to lenticular ascomata; long cylindrical to clavate, short pedicellate asci; small, fusiform to ellipsoidal ascospores with acute ends when compared to other Morosphaeria species. A multigene phylogeny obtained from a combined nuclear large subunit, small subunit, internal transcribed spacers rDNA and translation elongation factor 1-alpha sequence analysis revealed that M. muthupetensis is phylogenetically distinct and nested in between Morosphaeria velatispora and Morosphaeria ramunculicola and all these species constitute a strongly supported monophyletic clade sister to the genus Helicascus. Detailed descriptions and illustrations of M. muthupetensis are presented and compared with other Morosphaeria species.

Gnomoniopsis (Gnomoniaceae, Diaporthales) is a well-classified genus inhabiting leaves, branches and fruits of the hosts in three plant families, namely Fagaceae, Onagraceae and Rosaceae. In the present study, eighteen Gnomoniopsis isolates were obtained from diseased leaves of Fagaceae hosts collected from Fujian, Guangdong, Hainan, Henan, Jiangxi and Shaanxi provinces in China. Morphology from the cultures and phylogeny based on the 5.8S nuclear ribosomal DNA gene with the two flanking internally transcribed spacer (ITS) regions, the translation elongation factor 1-alpha (tef1) and the beta-tubulin (tub2) genes were employed to identify these isolates. As a result, seven species were revealed, viz. Gnomoniopsis castanopsidis, G. fagacearum, G. guangdongensis, G. hainanensis, G. rossmaniae and G. silvicola spp. nov, as well as a known species G. daii. In addition, G. daii was firstly reported on the host Quercus aliena.

The grass Ammophila breviligulata (American beachgrass) is known to host an endophyte of the genus Epichloë. Based on morphological characteristics it was originally identified as Acremonium typhinum var. ammophilae and is currently designated as Epichloë typhina var. ammophilae. However, the Epichloë species has not previously been identified based on DNA sequence data. Based on phylogenetic placement of beta-tubulin and translation elongation factor 1-alpha DNA sequences the endophyte is identified as a member of E. amarillans rather than E. typhina.

Abstract The hypersaline Inland Sea in Qatar constitutes a unique ecosystem characterized by salinities up to saturation, extreme temperature fluctuations, and limited rainfall. To reveal the fungal diversity of this environment, we isolated fungi from water samples collected at the Inland Sea. Taxonomic identification of the isolates was done via DNA barcoding of the ITS1 and ITS2 ribosomal DNA (rDNA) domains and the D1/D2 domains of the nuclear large subunit rDNA. Additional genes, including glyceraldehyde-3-phosphate dehydrogenase (gapdh) and translation elongation factor 1-alpha (tef1), were included for isolates of Alternaria, actin (Act) for Cladosporium, part of the beta-tubulin (BenA) and calmodulin (CaM) genes for Aspergillus and Penicillium. In total, 159 fungal isolates, including 85 Ascomycota and 74 Basidiomycota, were obtained from the water samples collected during four samplings in the winter and summer seasons. About 14% (22/159) of the strains, presumably novel species, were preliminarily identified to the genus level. This is the first report highlighting the diversity of fungi from the hypersaline Inland Sea in Qatar.
