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.

Specimens of a new pleosporalean taxon were obtained on the bark of Juniperus excels from the northern mountains of Oman; from the Jebel Akhdar (‘Green Hills’). Sequence analyses based on the regions of large subunit rRNA (LSU), small subunit rRNA (SSU), translation elongation factor 1-α (TEF) and internal transcribed spacers (ITS) were performed to resolve the phylogenetic relationships of the new taxon in Phaeosphaeriaceae. The data concluded that the taxon represents a novel genus of the family Phaeosphaeriaceae and the generic name Hydeomyces and the species name H. desertipleosporoides are introduced for the new taxon. An outline of the characters which differentiate the new genus from phylogenetically closely related genera Dematiopleospora and Dlhawksworthia is given and its morphology of asexual and sexual morphs is described.

Abstract The genus Neoconidiobolus was recently established to accommodate all members of the Conidiobolus subgenus Conidiobolus. Based on mitochondrial small subunit (mtSSU), nuclear large subunit (nucLSU) of rDNA and translation elongation factor 1-alpha (TEF1), this study further resolved the genus Neoconidiobolus into three clades, with three new taxa being added. They are N. kunyushanensis B. Huang & Y. Nie, sp. nov., N. lamprauges (Drechsler) B. Huang & Y. Nie, comb. nov., and N. nanodes (Drechsler) B. Huang & Y. Nie, comb. nov. Meanwhile, a morphologial comparison among species in the three clades and a key to the species of the genus Neoconidiobolus are provided herein.

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.

AbstractSpecies of Arthrinium are well-known plant pathogens, endophytes, or saprobes found in various terrestrial habitats. Although several species have been isolated from marine environments and their remarkable biological activities have been reported, marine Arthrinium species remain poorly understood. In this study, the diversity of this group was evaluated based on material from Korea, using morphological characterization and molecular analyses with the internal transcribed spacer (ITS) region, β-tubulin (TUB), and translation elongation factor 1-alpha (TEF). A total of 41 Arthrinium strains were isolated from eight coastal sites which represented 14 species. Eight of these are described as new to science with detailed descriptions.

A New Species

Arthrinium is a widely distributed genus occurring on various hosts and substrates. Members of Arthrinium were distinguished based on the phylogeny of combined internal transcribed spacers (ITS), translation elongation factor 1-alpha gene (tef1), and beta-tubulin gene (tub2). In the present study, a specimen of obvious stromata on Setaria viridis was collected in Beijing Forestry University. Identification based on characters of sexual morph on Setaria viridis culms, asexual morph from manual media, and phylogeny indicated that it is different from any known species. Hence, we proposed a new species for this taxon named Arthrinium setariae. Arthrinium setariae has much larger conidia than its phylogenetically close species, A. jiangxiense, and represented the first record of Arthrinium inhabiting the host genus, Setaria.

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.

A new endophytic fungus, described herein as Cunninghamella saisamornae, was isolated from soil collected from Chiang Mai Province, Thailand. This species was distinguished from the previously described Cunninghamella species by the presence of a chlamydospore formation, the lack of a zygospore stage and a maximum growth temperature of 45°C. Multi-gene phylogenetic analysis of internal transcribed spacers (ITS) and large subunit (LSU) of the nuclear ribosomal DNA (rDNA), along with the translation elongation factor 1-alpha (tef-1) genes, support the finding that C. saisamornae is distinct from other species within the genus Cunninghamella. A full description, color photographs, illustrations and a phylogenetic tree showing the position of C. saisamornae are provided.
