Sporidesmiellalignicola sp. nov., a new hyphomycetous fungus from freshwater habitats in China.

ABSTRACT:

Background

Freshwater fungi, growing on submerged wood, can promote the degradation of organisms and the reuse of rotten wood energy and play key roles in freshwater ecosystems. Here, a new hyphomycetous fungus, Sporidesmiellalignicola, was isolated and identified from submerged wood samples collected in a small stream in Jiangxi Province, south-eastern China.

New information

The new taxon was studied, based on morphological characters and phylogenetic analyses combined with LSU, ITS, TEF1α and RPB2 sequences data. Sporidesmiellalignicola was morphologically characterised by its pink colonies on PDA medium in prophase, macronematous, mononematous, solitary, brown, septate, unbranched, straight or slightly flexuous conidiophores with holoblastic, polyblastic, integrated, terminal, pale brown conidiogenous cells and cylindrical, narrowly clavate, broadly obovoid to cuneiform, 3-4-distoseptate, olivaceous brown or brown conidia with rounded apex. A phylogenetic tree was constructed, based on the combination of LSU, ITS, TEF1α and RPB2 sequences data.

Fluviispira multicolorata gen. nov., sp. nov. and Silvanigrella paludirubra sp. nov., isolated from freshwater habitats.

Project description:Strain 33A1-SZDPT was isolated from a small creek located in Puch, Austria. Strain SP-Ram-0.45-NSY-1T was obtained from a small pond located in Schönramer Moor, Germany. 16S rRNA gene sequence similarities between the type strain of Silvanigrella aquatica, currently the only member of the family Silvanigrellaceae, and strains 33A1-SZDPT and SP-Ram-0.45-NSY-1T of 94.1 and 99.1?%, respectively, suggested affiliation of the two strains with this family. Phylogenetic reconstructions with 16S rRNA gene sequences and phylogenomic analyses with amino acid sequences obtained from 103 single-copy genes suggested that the strains represent a new genus and a new species in the case of strain 33A1-SZDPT (=JCM 32978T=DSM 107810T), and a new species within the genus Silvanigrella in the case of strain SP-Ram-0.45-NSY-1T (=JCM 32975T=DSM 107809T). Cells of strain 33A1-SZDPT were motile, pleomorphic, purple-pigmented on agar plates, putatively due to violacein, and showed variable pigmentation in liquid media. They grew chemoorganotrophically and aerobically and tolerated salt concentrations up to 1.2?% NaCl (v/w). The genome size of strain 33A1-SZDPT was 3.4 Mbp and the G+C?content was 32.2?mol%. For this new genus and new species, we propose the name Fluviispira multicolorata gen. nov., sp. nov. Cells of strain SP-Ram-0.45-NSY-1T were motile, pleomorphic, red-pigmented and grew chemoorganotrophically and aerobically. They tolerated salt concentrations up to 1.1?% NaCl (v/w). The genome size of strain SP-Ram-0.45-NSY-1T was 3.9 Mbp and the G+C?content 29.3?mol%. For the new species within the genus Silvanigrella we propose the name Silvanigrella paludirubra sp. nov.

Saksenaea dorisiae sp. nov., a New Opportunistic Pathogenic Fungus from Europe.

Project description:A new species, Saksenaea dorisiae (Mucoromycotina, Mucorales), isolated from a water sample originating from a private well in Manastirica, Petrovac, in the Republic of Serbia (Europe), is described and illustrated. The new taxon is well supported by multilocus phylogenetic analysis that included the internal transcribed spacer (ITS) region, domains D1 and D2 of the 28S rRNA gene (LSU), and translation elongation factor-1? gene (tef-1?), and it is resolved in a clade with S. oblongispora and S. trapezispora. This fungus is characterized by its moderately slow growth at 15 and 37°C, sparse rhizoids, conical-shaped sporangia, and short-cylindrical sporangiospores. Saksenaea dorisiae is a member of the opportunistic pathogenic genus often involved in severe human and animal mucormycoses encountered in tropical and subtropical regions. Despite its sensitivity to several conventional antifungals (terbinafine and ciclopirox), the fungus can potentially evoke clinically challenging infections. This is the first novel taxon of the genus Saksenaea described from the moderately continental climate area of Europe.

<i>Blastosporiumpersicolor</i> gen. et sp. nov., a new helotialean fungus.

Project description:A new genus and species, Blastosporiumpersicolor, 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 B.persicolor in the Leotiomycetes class, Helotiales order.

Lignicolous freshwater ascomycota from Thailand: Phylogenetic and morphological characterisation of two new freshwater fungi: Tingoldiago hydei sp. nov. and T. clavata sp. nov. from Eastern Thailand.

Project description:Lignicolous freshwater fungi represent one of the largest groups of Ascomycota. This taxonomically highly diverse group plays an important role in nutrient and carbon cycling, biological diversity and ecosystem functioning. The diversity of lignicolous freshwater fungi along a north-south latitudinal gradient is currently being studied in Asia. In this paper, we introduce two novel freshwater taxa viz. Tingoldiago hydei sp. nov. and T. clavata sp. nov. which were collected from freshwater substrates in Eastern Thailand. Morphological comparison based on the size of ascomata, asci and ascospores, as well as multi-gene phylogenetic analyses based on LSU, SSU, ITS and TEF1-α DNA sequences, supports their placement in Tingoldiago (Lentitheciaceae). Descriptions and illustrations of these two new species are provided.

<i>Micromelanconis kaihuiae</i> gen. et sp. nov., a new diaporthalean fungus from Chinese chestnut branches in southern China.

Project description:Melanconis-like fungi are distributed in several families of Diaporthales, mainly Juglanconidaceae, Melanconidaceae, Melanconiellaceae and Pseudomelanconidaceae. A new Melanconis-like genus of Pseudomelanconidaceae was discovered on branches of Chinese chestnut (Castanea mollissima) in southern China, which was confirmed by both morphology and phylogenetic analysis of combined ITS, LSU, tef1a and rpb2 sequences. The new genus Micromelanconis is characterized by two types of conidia from natural substrate and manual media of PDA, respectively. Conidia from Chinese chestnut branches are pale brown, ellipsoid, multiguttulate, aseptate with hyaline sheath. While conidia from PDA plates are pale brown, long dumbbell-shaped, narrow at the middle and wide at both ends, multiguttulate, aseptate, and also with hyaline sheath. All Pseudomelanconidaceae species were only reported on tree branches in China until now. More interesting taxa may be discovered if detailed surveys on tree-inhabiting fungi are carried out in East Asia in the future.

Two new species of Jalapriya and a new record, Dictyocheirosporavinaya from freshwater habitats in China

Project description:Abstract Background Pleosporales is the largest order of Dothideomycetes. In recent years, systematics of Pleosporales have undergone considerable revisions. Dictyosporiaceae is one of the newly established families within this order proposed to accommodate holomorphic saprobic Dothideomycetes. Currently 18 genera are recognised in Dictyosporiaceae. New information The new species, Jalapriyaaquaticum sp. nov. and J.apicalivaginatum sp. nov. were collected from freshwater habitats in Gansu and Yunnan Provinces, China, respectively and are introduced, based on morphology and molecular analysis of combined ITS, LSU, SSU and TEF1-α sequence data. We also recovered one fresh collection of Dictyocheirosporavinaya D’souza, Bhat & K.D. Hyde, which is a new record for China. Jalapriyaaquaticum differs from extant species of Jalapriya in rows converging at the apex and apical cells with spherical-like appendages. Jalapriyaapicalivaginatum differs from extant species of Jalapriya in having the rows of conidia mostly arranged in a plane. The phylogenetic analysis place the new collections within Dictyosporiaceae (Pleosporales). Descriptions and illustrations of Jalapriyaaquaticum, J.apicalivaginatum and Dictyocheirosporavinaya are provided. A synopsis of characters of species of Jalapriya is also provided.

Muscodor kashayum sp. nov. - a new volatile anti-microbial producing endophytic fungus.

Project description:Muscodor kashayum (MycoBank no.: MB 803800; GenBank no.: KC481680) is a newly described endophytic fungus of a medicinal plant Aegle marmelos (Bael tree), growing in the tropical conserved rainforest in the Western Ghats of India. Muscodor kashayum possesses distinct morphological, molecular and physiological features from the earlier reported Muscodor species. The fungus forms characteristic rings of the ropy mycelium on potato dextrose agar medium. This sterile fungus is characterised by the presence of a pungent smell which is attributable to a blend of more than 23 volatile organic constituents, predominantly 3-cyclohexen-1-ol,1-(1,5-dimethyl-4-hexenyl)-4-methyl; 1,6-dioxacyclododecane-7,12-dione; 2,6-bis(1,1-dimethylethyl)-4-(1-oxopropyl) phenol; 2,4-di-tert-butylthiophenol and 4-octadecylmorpholine. In the in vitro anti-microbial assay using M. kashayum, growth of 75% of test fungi/yeasts and 72% of the test bacteria were completely inhibited. Therefore, M. Kashayum holds potential for future application to be used as a myco-fumigation agent.

Kombocles bakaiana gen. sp. nov. (Boletaceae), a new sequestrate fungus from Cameroon.

Project description:Kombocles bakaiana gen. sp. nov. is described as new to science. This sequestrate, partially hypogeous fungus was collected around and within the stilt root system of an ectomycorrhizal (ECM) tree of the genus Uapaca (Phyllanthaceae) in a Guineo-Congolian mixed tropical rainforest in Cameroon. Molecular data place this fungus in Boletaceae (Boletales, Agaricomycetes, Basidiomycota) with no clear relationship to previously described taxa within the family. Macro- and micromorphological characters, habitat, and DNA sequence data are provided. Unique morphological features and a molecular phylogenetic analysis of 304 sequences across the Boletales justify the recognition of the new taxa. Kombocles bakaiana is the fourth sequestrate Boletaceae described from the greater African tropics, and the first to be described from Cameroon.

Annulatascus nilensis sp. nov., a new freshwater ascomycete from the River Nile, Egypt.

Project description:Annulatascus nilensis sp. nov., from freshwater habitats in Egypt, is described, illustrated and compared to other species in the genus. Phylogenetic analyses of its LSU rDNA sequence with similar fungi placed the new species in the genus Annulatascus (Annulatascaceae, Sordariomycetidae incertae sedis). Annulatascus nilensis is characterized by immersed ascomata with an ascomatal neck oriented horizontally to the substrate surface, asci with a long, narrow stalk and massive bipartite apical ring, and 5-11-septate, hyaline ascospores surrounded by a large irregular, granular sheath that is not seen in water.

Polynucleobacter hirudinilacicola sp. nov. and Polynucleobacter campilacus sp. nov., both isolated from freshwater systems.

Project description:Strains MWH-EgelM1-30-B4T and MWH-Feld-100T were isolated from the water columns of two freshwater systems. Both strains represent delicate bacteria not easy to work with in laboratory experiments. Phylogenetic analyses of the 16S rRNA genes suggested that both strains were affiliated with the genus Polynucleobacter. Both strains share 16S rRNA gene sequence similarities of >99?% with eight free-living Polynucleobacter type strains, all affiliated with the cryptic species complex PnecC. The full-length 16S rRNA gene sequences of the two strains differ only in two and three positions, respectively, from the sequence of the closest related Polynucleobacter type strain. Genome sequencing of both strains revealed relatively small genome sizes of 2.0 Mbp and G+C?contents of 45?mol%. Phylogenetic analyses based on nucleotide sequences of 319 shared protein-encoding genes consistently placed the two strains in taxon PnecC but did not suggest an affiliation with one of the previously described species. Pairwise analyses of whole genome average nucleotide identities (gANI) with representatives of all previously described Polynucleobacter species resulted in both cases throughout in values <80?%. Pairwise comparison of the genomes of the two new strains resulted in gANI values of 83.3?%. All gANI analyses clearly suggested that strains MWH-EgelM1-30-B4T and MWH-Feld-100T represent two novel Polynucleobacter species. We propose for these novel species the names Polynucleobacter hirudinilacicola sp. nov. and Polynucleobacter campilacus sp. nov. and strains MWH-EgelM1-30-B4T (=DSM 23911T=LMG 30144T) and MWH-Feld-100T (=DSM 24007T=LMG 29705T) as the type strains, respectively.
