Deciduous Shrub

Rosa roxburghii Tratt., a deciduous shrub of the family Rosaceae, is usually used as food and medicinal materials and also cultivated as an ornamental. Plant endophytic fungi are a large class of microbial resources not fully researched, with great potential applications. Two strains of Ascodesmis and Talaromyces were isolated during a survey of biodiversity on endophytic fungi of R. roxburghii in China. Multigene phylogenetic analyses showed that each of the two fungi formed a distinct lineage and separated from known congeneric species and they are proposed as two novel taxa. Ascodesmis rosicola sp. nov. usually has one or two conspicuous simple or branched ridges extending to the majority of the ascospore surface and remarkably small asci, distinguishing it from the previously-described species in the genus Ascodesmis. Talaromyces rosarhiza sp. nov., of the section Talaromyces, is closely related to T. francoae. It differs from the latter by having both monoverticillate and biverticillate conidiophores, while those of T. francoae are biverticillate. Both novel endophytes are illustrated and described.

Ophiocordyceps is entomopathogenic and the largest studied genus in the family Ophiocordycipitaceae. Many species in this genus have been reported from Thailand. The first new species introduced in this paper, Ophiocordycepsglobiceps, differs from other species based on its smaller perithecia, shorter asci and secondary ascospores and additionally, in parasitising fly species. Phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB1 sequence data indicate that O.globiceps forms a distinct lineage within the genus Ophiocordyceps as a new species. The second new species, Ophiocordycepssporangifera, is distinguished from closely related species by infecting larvae of insects (Coleoptera, Elateridae) and by producing white to brown sporangia, longer secondary synnemata and shorter primary and secondary phialides. We introduce O.sporangifera based on its significant morphological differences from other similar species, even though phylogenetic distinction is not well-supported.

Taxonomic System

The fungal genus Conidiobolus sensu lato was delimited into four genera based on morphology and phylogeny. However, the taxonomic placement of C. parvus has not been determined until now. Here, we show that C. parvus belongs to a distinct lineage based on mitochondrial (mtSSU) and nuclear (TEF1 and nrLSU) phylogenetic analyses. Phylogenetic analyses further revealed a new species as sister to C. parvus. We identified a synapomorphy uniting these lineages (azygospore production) that was not observed in other allied genera of the family Ancylistaceae, and erected a new genus Azygosporusgen. nov. for this monophyletic group, with a new combination, A. parvuscomb. nov. as the type species. Within Azygosporus, the novel species A. macropapillatussp. nov. was introduced from China based on morphological characteristics and molecular evidence, which is characterized by its prominent basal papilla, in comparison to other closely related species, measuring 7.5–10.0×5.0–10.0 µm. Our study resolved the phylogenetic placement of C. parvus and improved the taxonomic system of the Ancylistaceae family.

Rosa Roxburghii

Rosa roxburghii Tratt. is widely applied in food, cosmetics, and traditional medicine, and has been demonstrated to possess diverse bioactivities. Plant endophytic fungi are important microbial resources with great potential for application in many fields. They not only establish mutualistic symbiosis with host plants but also produce a variety of bioactive compounds. Therefore, in the present study, endophytic fungi were isolated from R. roxburghii, the diversity and antimicrobial activities were evaluated. As a result, 242 strains of endophytic Sordariomycetes were successfully isolated. Multigene phylogenetic analyses showed that these isolates included eight orders, 19 families, 33 genera. The dominant genera were Diaporthe (31.4%), Fusarium (14.4%), Chaetomium (7.9%), Dactylonectria (7.0%), Graphium (4.5%), Colletotrichum (4.1%), and Clonostachys (4.1%). For different tissues of R. roxburghii, alpha diversity analysis revealed that the diversity of fungal communities decreased in the order of root, fruit, stem, flower, leaf, and seed, and Clonostachys and Dactylonectria exhibited obvious tissue specificity. Meanwhile, functional annotation of 33 genera indicated that some fungi have multitrophic lifestyles combining endophytic, pathogenic, and saprophytic behavior. Additionally, antimicrobial activities of endophytic Sordariomycetes against Lasiodiplodia theobromae, Botryosphaeria dothidea, Colletotrichum capsici, Pyricularia oryzae, Rhizoctonia solani, Fusarium oxysporum, Pseudomonas syringae, Pantoea agglomerans, Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa were screened. Dual culture test assays showed that there were 40 different endophytic species with strong inhibition of at least one or moderate inhibition of two or more against the 12 tested strains. The results from the filter paper diffusion method suggested that extracellular metabolites may be more advantageous than intracellular metabolites in the development of antimicrobial agents. Eleven isolates with good activities were screened. In particular, Hypomontagnella monticulosa HGUP194009 and Nigrospora sphaerica HGUP191020 have shown promise in both broad-spectrum and intensity. Finally, some fungi that commonly cause disease have been observed to have beneficial biological activities as endophytic fungi. In conclusion, this study showed the species composition, alpha diversity, and lifestyle diversity of endophytic Sordariomycetes from R. roxburghii and demonstrated these isolates are potential sources for exploring antimicrobial agents.

A New Species

During a survey of microfungi associated with palms from karst formations, three novel ascomycetes were found from decaying petioles of Trachycarpus fortunei (Arecaceae) in Guizhou, China. Multi-gene phylogenetic analyses based on a combined SSU, ITS, LSU, RPB2 and TEF1α sequence data showed that these collections were affiliated to Brunneofusispora and Neooccultibambusa in the family Occultibambusaceae. A new species Brunneofusispora inclinatiostiola is introduced. It is phylogenetically close to B. clematidis but represents a distinct lineage. Morphologically, it differs from the latter in having immersed ascomata with eccentric, periphysate ostiole and smaller ascospores. Morpho-phylogenetic evidence also revealed two new Neooccultibambusa species, N. kaiyangensis and N. trachycarpi. Together with the generic type N. chiangraiensis, they formed a distinct lineage within the genus Neooccultibambusa. Three novel palmicolous fungi of Occultibambusaceae are described, illustrated and notes on their identification are provided. The ecological significance of the new taxa and the phylogenetic relationship of genera in Occultibambusaceae is discussed.

Phylogenomic Analyses

A Gram-reaction-negative, motile by gliding, rod-shaped bacterium, designated strain GH4-78T, was isolated from the tidal mudflat of a beach in the Republic of Korea. Cells were aerobic, catalase-positive, oxidase-negative and produced cream-coloured colonies. Q-8 was the only isoprenoid quinone. The major fatty acids were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c), summed feature 3 (C16 : 1  ω6c and/or C16 : 1  ω7c) and C16 : 0. The major polar lipids are phosphatidylethanolamine and phosphatidylglycerol. Results of phylogenetic analyses based on 16S rRNA gene sequences revealed that strain GH4-78T formed a distinct lineage with Halioglobus sediminis (98.2 % sequence similarity). The DNA G+C content was 59.9 mol%. The average nucleotide identity value with the closest relative was 82.90 %. On the basis of the results from phenotypic, chemotaxonomic, phylogenetic and phylogenomic analyses, strain GH4-78T (=KCTC 62383T=DSM 106349T) represents a novel species of a new genus in the family Halieaceae , for which the name Seongchinamella unica gen. nov., sp. nov. is proposed. Moreover, the transfers of Halioglobus sediminis Han et al. 2019 to Seongchinamella sediminis comb. nov. and Halioglobus lutimaris Shi et al. 2018 to Pseudohalioglobus gen. nov. as Pseudohalioglobus lutimaris comb. nov. are also proposed, with the emended description of the genus Halioglobus .

During fungal diversity studies on ascomycetes from karst landforms in southwest China, two taxa were collected and morphologically identified as Lophiotrema species based on their immersed ascomata, crest-like ostioles, cylindrical, short pedicellate asci and fusiform ascospores. Multi-gene phylogenetic analyses based on a combined LSU-TEF1-α-SSU-ITS-RPB2 sequence data also confirmed their phylogenetic placement within the family Lophiotremataceae, where they clustered with reported Lophiotrema species with strong statistical support. Lophiotrema hydei sp. nov. is introduced and the species forms a distinct lineage which is sister to L. neohysterioides. Morphologically, Lophiotrema hydei differs from L. neohysterioides by its unique appearance of ascomata and different ascospore ornamentation. Another species is identified as L. neohysterioides based on morphological characteristics and phylogenetic data, and it is reported as the new record from China.

Hyphodontia sensu lato, belonging to Hymenochaetales, accommodates corticioid wood-inhabiting basidiomycetous fungi with resupinate basidiocarps and diverse hymenophoral characters. Species diversity of Hyphodontia sensu lato has been extensively explored worldwide, but in previous studies the six accepted genera in Hyphodontia sensu lato, viz. Fasciodontia, Hastodontia, Hyphodontia, Kneiffiella, Lyomyces and Xylodon were not all strongly supported from a phylogenetic perspective. Moreover, the relationships among these six genera in Hyphodontia sensu lato and other lineages within Hymenochaetales are not clear. In this study, we performed comprehensive phylogenetic analyses on the basis of multiple loci. For the first time, the independence of each of the six genera receives strong phylogenetic support. The six genera are separated in four clades within Hymenochaetales: Fasciodontia, Lyomyces and Xylodon are accepted as members of a previously known family Schizoporaceae, Kneiffiella and Hyphodontia are, respectively, placed in two monotypic families, viz. a previous name Chaetoporellaceae and a newly introduced name Hyphodontiaceae, and Hastodontia is considered to be a genus with an uncertain taxonomic position at the family rank within Hymenochaetales. The three families emerged between 61.51 and 195.87 million years ago. Compared to other families in the Hymenochaetales, these ages are more or less similar to those of Coltriciaceae, Hymenochaetaceae and Oxyporaceae, but much older than those of the two families Neoantrodiellaceae and Nigrofomitaceae. In regard to species, two, one, three and 10 species are newly described from Hyphodontia, Kneiffiella, Lyomyces and Xylodon, respectively. The taxonomic status of additional 30 species names from these four genera is briefly discussed; an epitype is designated for X. australis. The resupinate habit and poroid hymenophoral configuration were evaluated as the ancestral state of basidiocarps within Hymenochaetales. The resupinate habit mainly remains, while the hymenophoral configuration mainly evolves to the grandinioid-odontioid state and also back to the poroid state at the family level. Generally, a taxonomic framework for Hymenochaetales with an emphasis on members belonging to Hyphodontia sensu lato is constructed, and trait evolution of basidiocarps within Hymenochaetales is revealed accordingly.
