RESUMEN
Background: Mycena (Pers.) Roussel (1806) is a large genus of Mycenaceae known for having small to medium-sized basidiomata. It is typified by the species Mycenagalericulata (Scop.) Gray. For years, many mycologists have made important contributions to understanding Mycena and several monographs have been published. Three specimens were collected from China that belonged to the genus Mycena. On the basis of morphological analysis and phylogenetic analyses employing DNA sequences, a new species is described. New information: Mycenabrunnescens sp. nov. is described as a new species from subtropical areas of China. It is characterised by its brown pileus, whitish lamellae that turns brown when bruised, orange to brown lamellae edges, the absence of pleurocystidia and cheilocystidia with simple or branched excrescences at the apex containing yellowish-brown contents. We performed phylogenetic analyses on a concatenated dataset comprising the internal transcribed spacer and large subunit regions of nuclear ribosomal RNA using Bayesian Inference and Maximum Likelihood methods. The result showed that the new taxon clustered in an independent group and is closely related to M.albiceps and M.flosoides.
RESUMEN
A novel moderately halophilic, Gram-stain-negative, catalase- and oxidase-positive, strictly aerobic, non-sporulating, non-motile rod, designated strain JSM 104105 T, was isolated from human faeces. Strain JSM 104105 T was able to grow with 0.5-18% (w/v) NaCl (optimum 4-9%), at pH 6-10.5 (optimum pH 7-8) and at 10-40 °C (optimum 30 °C) in complex media. The major cellular fatty acids were C18:1ω7c, C16:0, C16:1ω7c and/or C16:1ω6c, C19:0 cyclo ω8c and C12:0 3-OH. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified glycolipid and three unidentified phospholipids. The predominant respiratory quinone was Q-9 and the genomic DNA G + C content was 64.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 104105 T should be assigned to the genus Halomonas, and was most closely related to Halomonas gudaonensis SL014B-69 T (99.0% sequence similarity), followed by Halomonas azerbaijanica TBZ202T (98.6%) and Halomonas lysinitropha 3(2)T (97.3%). The whole genomic analysis showed that strain JSM 104105 T constituted a different taxon separated from the recognized Halomonas species. Combined data from phenotypic and genotypic studies demonstrated that strain JSM 104105 T represents a new species of the genus Halomonas, for which the name Halomonas faecis sp. nov. is proposed. The type strain is JSM 104105 T (= CCTCC AB 2014160 T = CGMCC 1.12945 T = KCTC 42146 T).

The sequence similarities between the novel isolate and the type strains of other recognized Halobacillus species ranged from 97.6% (with Halobacillus alkaliphilus) to 95.2% (with Halobacillus kuroshimensis). The results of the phylogenetic analyses, combined with DNA-DNA relatedness data, phenotypic characteristics and chemotaxonomic information, support that strain JSM 071077(T) represents a new species of the genus Halobacillus, for which the name Halobacillus hunanensis sp. nov. is proposed. The type strain is JSM 071077(T) (=DSM 21184(T) = KCTC 13235(T)).

A Gram-positive-staining, moderately halophilic, strictly aerobic, catalase- and oxidase-positive, rod-shaped bacterium, designated strain JSM 076056(T), was isolated from a sea urchin collected from the South China Sea. Cells were motile by means of peritrichous flagella and formed ellipsoidal endospores lying in subterminal swollen sporangia. Strain JSM 076056(T) was able to grow at salinities of 2-25 % (w/v) total salts and at pH 6.0-10.0 and 15-40 degrees C; optimum growth was observed with 5-10 % (w/v) total salts and at pH 7.0-8.0 and 25-30 degrees C. It was incapable of growing with NaCl as the sole salt. meso-Diaminopimelic acid was present in the cell-wall peptidoglycan. The major cellular fatty acids were iso-C(15 : 0), iso-C(16 : 0), iso-C(14 : 0,) anteiso-C(15 : 0) and C(16 : 1)omega7c alcohol. The predominant respiratory quinone was MK-7 and the genomic DNA G+C content was 45.5 mol%. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 076056(T) belonged to the family Bacillaceae and was related most closely to the type strains of the two recognized species of the genus Pontibacillus, namely Pontibacillus chungwhensis BH030062(T) (96.4 % sequence similarity) and Pontibacillus marinus BH030004(T) (96.2 %); these three strains formed a robust cluster in the phylogenetic tree. In combination, the phylogenetic, phenotypic and chemotaxonomic data indicate that strain JSM 076056(T) represents a novel species of the genus Pontibacillus, for which the name Pontibacillus halophilus sp. nov. is proposed. The type strain is JSM 076056(T) (=CCTCC AA 207029(T) =DSM 19796(T) =KCTC 13190(T)).

A novel non-sporulating, non-motile, catalase- and oxidase-positive, facultatively anaerobic, moderately halophilic, Gram-positive coccus, designated JSM 076033(T), was isolated from a sea urchin (Hemicentrotus pulcherrimus) collected from the South China Sea. Strain JSM 076033(T) was able to grow in the presence of 0.5-25.0 % (w/v) total salts and at pH 6.0-10.0 and 10-45 degrees C; optimum growth was observed with 5.0-10.0 % (w/v) total salts and at pH 7.0-8.0 and 25-30 degrees C. The major amino acid constituents of the cell wall were glycine, lysine and alanine. The major cellular fatty acids were anteiso-C(15 : 0), iso-C(15 : 0) and anteiso-C(17 : 0). The respiratory quinones were MK-7 (60.7 %) and MK-6 (39.3 %) and the polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified phospholipid. The DNA G+C content was 40.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain JSM 076033(T) should be assigned to the genus Jeotgalicoccus. The sequence similarities between the novel isolate and the type strains of recognized Jeotgalicoccus species were in the range 95.2-97.2 %. The results of the phylogenetic analysis, combined with DNA-DNA relatedness data, phenotypic characteristics and chemotaxonomic information, support the view that strain JSM 076033(T) represents a novel species of the genus Jeotgalicoccus, for which the name Jeotgalicoccus marinus sp. nov. is proposed. The type strain is JSM 076033(T) (=CCTCC AA 207028(T) =DSM 19772(T) =KCTC 13189(T)).

A novel Gram-negative, non-sporulating, moderately halophilic, facultatively alkaliphilic, catalase- and oxidase-positive, obligately aerobic bacterium, strain YIM-Y25(T), was isolated from a subterranean brine sample collected from a salt mine in Yunnan, south-west China. Cells were spirilla, motile by monopolar flagella, with meso-diaminopimelic acid in the cell-wall peptidoglycan. Growth occurred with 1-15 % (w/v) NaCl (optimum 5 %), at pH 6.0-10.0 (optimum pH 8.0) and at 15-50 degrees C (optimum 35-40 degrees C). Ubiquinone Q-8 was the predominant respiratory quinone. Polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylamine and an unidentified phospholipid. The major cellular fatty acids were C(18 : 1)omega7c, iso-C(16 : 0), C(16 : 0) and C(16 : 1). The genomic DNA G+C content was 58.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM-Y25(T) was most closely related to the type strain of the sole recognized species of the genus Saccharospirillum, Saccharospirillum impatiens EL-105(T) (sequence similarity 97.0 %), and these two strains formed a robust lineage in the phylogenetic tree. The level of DNA-DNA relatedness between them was 12.6 %. The combination of phylogenetic analysis, phenotypic differences, chemotaxonomic properties and DNA-DNA hybridization data supported the view that this strain represents a novel species of the genus Saccharospirillum, for which the name Saccharospirillum salsuginis sp. nov. is proposed, with YIM-Y25(T) (=CCTCC AA 207033(T) =KCTC 22169(T)) as the type strain.
