Morphological and phylogenetic characterisations reveal three new species of Samsoniella (Cordycipitaceae, Hypocreales) from Guizhou, China.

ABSTRACT: Samsoniella species have been found on lepidopteran larvae or pupae buried in soil or leaf litter. Three new species, Samsoniella hymenopterorum, S. coleopterorum and S. lepidopterorum, parasitic on hymenopteran larvae, coleopteran larvae and lepidopteran pupae, respectively, are reported. Morphological comparisons with extant species and DNA-based phylogenies from analysis of a multigene (ITS, RPB1, RPB2 and TEF) dataset supported the establishment of the new species. Unusually, all three new species have mononematous conidiophores. The new species are clearly distinct from other species in Samsoniella occurring in separate subclades.

Taxonomic and phylogenetic characterizations reveal four new species of Simplicillium (Cordycipitaceae, Hypocreales) from Guizhou, China.

Project description:Simplicillium species are commonly found from soil, seawater, rock surface, decayed wood, air and as symbiotic, endophytic, entomopathogenic and mycoparasitic fungi. Minority insect-associated species was reported. Simplicillium coccinellidae, S. hymenopterorum, S. neolepidopterorum and S. scarabaeoidea were introduced as the newly insect-associated species. The phylogenetic analyses of two combined datasets (LSU + RPB1 + TEF and SSU + ITS + LSU) revealed that S. coccinellidae and S. hymenopterorum were both nested in an independent clade. S. neolepidopterorum and S. scarabaeoidea have a close relationship with S. formicidae and S. lepidopterorum, respectively. S. neolepidopterorum can be easily distinguished from S. formicidae by ellipsoidal to cylindrical, solitary conidia which occasionally gather in short imbricate chains. S. scarabaeoidea could be easily distinguished from S. lepodopterorum by having longer phialides and larger conidia. Based on the morphological and phylogenetic conclusion, we determine the four newly generated isolates as new species of Simplicillium and a new combination is proposed in the genus Leptobacillium.

Morphological and Phylogenetic Characterization Reveals Five New Species of Samsoniella (Cordycipitaceae, Hypocreales).

Project description:Samsoniella is a very important fungal resource, with some species in the genus having great medical, economic and ecological value. This study reports five new species of Samsoniella from Yunnan Province and Guizhou Province in Southwestern China and Dole Province in Vietnam, providing morphological descriptions, illustrations, phylogenetic placements, associated hosts and comparisons with allied taxa. Based on morphological observations and phylogenetic analyses of combined nrSSU, nrLSU, tef-1α, rpb1 and rpb2 sequence data, it was determined that these five new species were located in the clade of Samsoniella and different from other species of Samsoniella. The five novel species had morphologies similar to those of other species in the genus, with bright orange cylindrical to clavate stromata (gregarious). The fertile part lateral sides usually had a longitudinal ditch without producing perithecia, and superficial perithecia. The phialides had a swollen basal portion, tapering abruptly into a narrow neck and oval or fusiform one-celled conidia, often in chains. The morphological characteristics of 23 species in Samsoniella, including five novel species and 18 known taxa, were also compared in the present study.

Morphology and multigene phylogeny reveal three new species of Samsoniella (Cordycipitaceae, Hypocreales) from spiders in China.

Project description:The genus Samsoniella was erected based on orange cylindrical to clavate stromata, superficial perithecia and conidiophores with Isaria-like phialides and to segregate them from the Akanthomyces group. In this study, based on morphological features and multigene (SSU, LSU, TEF, RPB1 and RPB2) phylogenetic analysis six Samsoniella species parasitizing spiders were collected in China. Three of them belong to known species S.alpina, S.erucae and S.hepiali. Three new species S.anhuiensissp. nov., S.araneasp. nov. and S.fusiformisporasp. nov. are illustrated and described. They are clearly distinct from other species in Samsoniella occurring in independent subclades. Furthermore, among the four insect-pathogenic fungi specimens collected from similar sites, three of them were identified as the new species described below. Our study significantly broadens the host range of Samsoniella from Insecta to Arachnida, marking a noteworthy expansion in understanding the ecological associations of these fungi. Additionally, the identification of both mononematous and synnematous conidiophores in our study not only expands the knowledge of Samsoniella species but also provides a basis for future research by comparing the ecological significance between these conidiophore types. In conclusion, our study enhances the understanding of Samsoniella diversity, presenting a refined phylogenetic framework and shedding light on the ecological roles of these fungi in spider parasitism.

Three novel insect-associated species of Simplicillium (Cordycipitaceae, Hypocreales) from Southwest China.

Project description:In this paper, we introduce three new species of Simplicillium, viz. S. cicadellidae, S. formicidae and S. lepidopterorum, which were isolated from an infected leafhopper, ant and carpenterworm, respectively. Morphological comparisons and phylogenetic analyses based on multigene datasets (LSU+RPB1+RPB2+TEF and ITS+LSU) support the establishment of the three new species. Simplicillium cicadellidae was distinguished from other species in morphological characteristics by having smaller phialides and ellipsoidal conidia, and lacking octahedral crystals. The reverse of colonies were yellowish (#FFBF00), especially in the middle, and radially sulcate. Simplicillium formicidae was morphologically distinguished from other by having longer phialides and filiform to fusoid conidia, and by lacking octahedral crystals. Simplicillium lepidopterorum was morphologically distinguished from other species by having smaller, ellipsoidal to fusiform conidia, and by lacking octahedral crystals. The reverse of the colony was pale white. The three new species are likely to be nourished by plant to animal (especially insect) nutrients based on the evolutionary pattern of the Hypocreales, and they are described herein as being clearly distinct from other species in Simplicillium.

Morphological and phylogenetic analyses reveal three new species of Fusarium (Hypocreales, Nectriaceae) associated with leaf blight on Cunninghamialanceolata in China.

Project description:Chinese fir (Cunninghamialanceolata) is a special fast-growing commercial tree species in China with high economic value. In recent years, leaf blight disease on C.lanceolata has been observed frequently. The diversity of Fusarium species associated with leaf blight on C.lanceolata in China (Fujian, Guangxi, Guizhou, and Hunan provinces) was evaluated using morphological study and molecular multi-locus analyses based on RNA polymerase second largest subunit (RPB2), translation elongation factor 1-alpha (TEF-1α), and RNA polymerase largest subunit (RPB1) genes/region as well as the pairwise homoplasy index tests. A total of five Fusarium species belonging to four Fusarium species complexes were recognized in this study. Two known species including Fusariumconcentricum and F.fujikuroi belonged to the F.fujikuroi species complex, and three new Fusarium species were described, i.e., F.fujianense belonged to the F.lateritium species complex, F.guizhouense belonged to the F.sambucinum species complex, and F.hunanense belonged to the F.solani species complex. To prove Koch's postulates, pathogenicity tests on C.lanceolata revealed a wide variation in pathogenicity and aggressiveness among the species, of which F.hunanense HN33-8-2 caused the most severe symptoms and F.fujianense LC14 led to the least severe symptoms. To our knowledge, this study also represented the first report of F.concentricum, F.fujianense, F.fujikuroi, F.guizhouense, and F.hunanense causing leaf blight on C.lanceolata in China.

Morphological and phylogenetic analyses reveal three new species of Diaporthe from Yunnan, China.

Project description:Species of Diaporthe have often been reported as plant pathogens, endophytes or saprobes, commonly isolated from a wide range of plant hosts. Sixteen strains isolated from species of ten host genera in Yunnan Province, China, represented three new species of Diaporthe, D. chrysalidocarpi, D. machili and D. pometiae as well as five known species D. arecae, D. hongkongensis, D. middletonii, D. osmanthi and D. pandanicola. Morphological comparisons with known species and DNA-based phylogenies based on the analysis of a multigene (ITS, TUB, TEF, CAL and HIS) dataset support the establishment of the new species. This study reveals that a high species diversity of Diaporthe with wide host ranges occur in tropical rainforest in Yunnan Province, China.

Morphological and phylogenetic evidence reveal three new Pseudohydnum (Auriculariales, Basidiomycota) species from North China.

Project description:Pseudohydnum is characterized by gelatinous basidiomata with hydnoid hymenophores and longitudinally septate basidia. In this study, samples of the genus from North China were examined morphologically and phylogenetically using a dataset of the internal transcribed spacer of the ribosomal RNA gene and the nuclear large subunit rDNA. This study describes three new species, namely Pseudohydnum abietinum, Pseudohydnum candidissimum, and Pseudohydnum sinobisporum. Pseudohydnum abietinum is characterized by pileate and pale clay pink basidiomata when fresh, with a rudimentary stipe base, four-celled basidia, and broadly ellipsoid to ovoid or subglobose basidiospores (6-7.5 × 5-6.3 μm). P. candidissimum is characterized by very white basidiomata when fresh, frequently four-celled basidia, and broadly ellipsoid to subglobose basidiospores (7.2-8.5 × 6-7 μm). P. sinobisporum is characterized by ivory basidiomata when fresh, two-celled basidia, ovoid to broadly ellipsoid, or subglobose basidiospores (7.5-9.5 × 5.8-7.2 μm). The main characteristics, type localities, and hosts of Pseudohydnum species are listed.

Three New Species of Clonostachys (Hypocreales, Ascomycota) from China.

Project description:Three new species of Clonostachys are introduced based on specimens collected from China. Clonostachys chongqingensis sp. nov. is distinguished by pale yellow to pale orange-yellow perithecia with a very low papilla, clavate to subcylindrical asci possessing ellipsoidal to elongate-ellipsoidal spinulose ascospores 13-16 × 4.5-5.5 μm; it has acremonium- to verticillium-like conidiophores and ellipsoidal to rod-shaped conidia. Clonostachys leptoderma sp. nov. has pinkish-white subglobose to globose perithecia on a well-developed stroma and with a thin perithecial wall, clavate to subcylindrical asci with ellipsoidal to elongate-ellipsoidal spinulose ascospores 7.5-11 × 2.5-3.5 μm; it produces verticillium-like conidiophores and ellipsoidal to subellipsoidal conidia. Clonostachys oligospora sp. nov. features solitary to gregarious perithecia with a papilla, clavate asci containing 6-8 smooth-walled ascospores 9-17 × 3-5.5 μm; it forms verticillium-like conidiophores and sparse, subfusiform conidia. The morphological characteristics and phylogenetic analyses of combined nuclear ribosomal DNA ITS1-5.8S-ITS2 and beta-tubulin sequences support their placement in Clonostachys and their classification as new to science. Distinctions between the novel taxa and their close relatives are compared herein.

Morphological and phylogenetic analyses reveal a new genus and two new species of Tubakiaceae from China.

Project description:Species of Tubakiaceae have often been reported as plant pathogens or endophytes, commonly isolated from a wide range of plant hosts. The isolated fungi were studied through a complete examination, based on multilocus phylogenies from combined datasets of ITS/LSU/rpb2 and ITS/tef1/tub2, in conjunction with morphological characteristics. Five strains isolated from Lithocarpusfohaiensis and Quercuspalustris in China represented a new genus of Tubakiaceae, Obovoideisporodochium and three species, viz. Obovoideisporodochiumlithocarpi sp. nov., Tubakialushanensis sp. nov. and T.dryinoides.
