Three new species of Trichoderma (Hypocreales, Hypocreaceae) from soils in China.

ABSTRACT: Trichoderma spp. are diverse fungi with wide distribution. In this study, we report on three new species of Trichoderma, namely T.nigricans, T.densissimum and T.paradensissimum, collected from soils in China. Their phylogenetic position of these novel species was determined by analyzing the concatenated sequences of the second largest nuclear RNA polymerase subunit encoding gene (rpb2) and the translation elongation factor 1- alpha encoding gene (tef1). The results of the phylogenetic analysis showed that each new species formed a distinct clade: T.nigricans is a new member of the Atroviride Clade, and T.densissimum and T.paradensissimum belong to the Harzianum Clade. A detailed description of the morphology and cultural characteristics of the newly discovered Trichoderma species is provided, and these characteristics were compared with those of closely related species to better understand the taxonomic relationships within the Trichoderma.

Two new Trichoderma species (Hypocreales, Hypocreaceae) isolated from decaying tubers of Gastrodiaelate.

Project description:Species of Trichoderma are widely distributed around the world. In this study, two new species in Trichoderma, named as T.albidum and T.variegatum, were introduced and illustrated. These species were isolated from diseased tubers of Gastrodiaelata in China and identified based on morphological characteristics and multi-gene sequence analyses of three loci that is the internal transcribed spacer regions of the ribosomal DNA (ITS), the translation elongation factor 1-α encoding gene (tef1-α) and the gene encoding the second largest nuclear RNA polymerase subunit (rpb2). Distinctions between the new species and their close relatives were discussed. According to results of the phylogenetic analyses, T.albidum belonged to the Harzianum clade and T.variegatum are grouped with species of the Spirale clade. The expansion of two clades provided research foundations for the prevention and control of tuber diseases in G.elata.

New combinations in Trichoderma (Hypocreaceae, Hypocreales).

Project description:Unitary nomenclature demands the use of a single name for pleomorphic fungi determined according to priority. For this reason combinations in Trichoderma are here provided for 46 species for which such a combination is lacking. Although many more such species are known, only those are included here that are dealt with in more recent papers and where some DNA data are available in GenBank, even if erroneous; for other species it is strongly recommended to consult databases like Index Fungorum or MycoBank. Information on types is provided for most species, and representative cultures, GenBank accessions for tef1 and rpb2, and important references are given for all species.

Three New Species of Fusicolla (Hypocreales) from China.

Project description:To explore the species diversity of the genus Fusicolla, specimens from Henan, Hubei and Jiangsu Provinces in China are examined, and three undescribed taxa are encountered. The morphological characteristics and DNA sequence analyses of the combined acl1, ITS, LSU, rpb2 and tub2 regions support their placement in Fusicolla and their recognition as new species. Fusicolla aeria sp. nov. is distinguished by the formation of abundant aerial mycelia on PDA, falcate, (1-)3-septate macroconidia 16-35 × 1.5-2.8 μm and subcylindrical, aseptate microconidia 7.5-13 × 0.8-1.1 μm. Fusicolla coralloidea sp. nov. has a coralloid colony on PDA, falcate, 2-5-septate macroconidia 38-70 × 2-4.5 μm and rod-shaped to ellipisoidal, aseptate microconidia 2-7 × 1-1.9 μm. Fusicolla filiformis sp. nov. is characterized by filiform, 2-6-septate macroconidia 28-58 × 1.5-2.3 μm and lacking microconidia. Morphological differences between these novel species and their close relatives are compared in detail. The previously recorded species of the genus in China are listed and a key to these taxa is provided.

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.

Five new species of Trichoderma from moist soils in China.

Project description:Trichoderma isolates were collected from moist soils near a water source in different areas of China. ITS sequences were submitted to MIST (Multiloci Identification System for Trichoderma) and meets the Trichoderma [ITS76] standard. Combined analyses of phylogenetic analyses of both phylograms (tef1-α and rpb2) and morphological characteristics, revealed five new species of Trichoderma, namely Trichodermahailarense, T.macrofasciculatum, T.nordicum, T.shangrilaense and T.vadicola. Phylogenetic analyses showed T.macrofasciculatum and T.shangrilaense belong to the Polysporum clade, T.hailarense, while T.nordicum and T.vadicola belong to the Viride clade. Each new taxon formed a distinct clade in phylogenetic analysis and have unique sequences of tef1-α and rpb2 that meet the Trichoderma new species standard. The conidiation of T.macrofasciculatum typically appeared in white pustules in concentric rings on PDA or MEA and its conidia had one or few distinctly verrucose. Conidiophores of T.shangrilaense are short and rarely branched, phialides usually curved and irregularly disposed. The aerial mycelium of T.hailarense and T.vadicola formed strands to floccose mat, conidiation tardy and scattered in tufts, conidiophores repeatedly rebranching in dendriform structure. The phialides of T.nordicum lageniform are curved on PDA and its conidia are globose to obovoidal and large.

Unveiling two new species of Trichoderma (Hypocreales, Hypocreaceae) that cause green mold disease on Strophariarugosoannulata from Guizhou Province, China.

Project description:Strophariarugosoannulata is an important edible mushroom in China, but green mold disease has caused significant production and economic losses. In this study, two new pathogens Trichodermastrophariensis and T.viridistromatis were identified as the causal agents of this disease. During October-November 2023, six strains of the fungal pathogen were isolated from infected fruiting bodies of S.rugosoannulata and identified based on morphological characteristics and molecular phylogenetic analyses of internal transcribed spacer (nrITS), the second largest RNA polymerase II subunit (rpb2) and the partial translation elongation factor 1-alpha (tef1-α) region. The representative isolates of the pathogenic green mold Trichoderma species were used to perform a pathogenicity test with spore suspensions, resulting in symptoms similar to those observed in the cultivated field. The same pathogens were successfully re-isolated, thereby fulfilling Koch's postulates. Detailed morphological descriptions, illustrations, culture characteristics, and comparisons with morphologically similar and closely related species are provided.

Reconsideration of Protocrea (Hypocreales, Hypocreaceae).

Project description:The genus Protocrea is redefined, based on holotype and fresh specimens of its type species P. farinosa, using morphology of teleomorph and anamorph and phylogenetic analyses of rpb2 sequences. Data based on currently available specimens suggest the existence of three well defined and three still unnamed species. Apart from the type, P. farinosa, none of the species originally included are accepted in the genus. Species of Protocrea are characterized by perithecia formed in or on a subiculum, bicellular ascospores that disarticulate at the septum while still in the ascus and by anamorphs belonging to Gliocladium sensu stricto. For Hypocrea farinosa sensu auct. the new species H. decipiens is introduced. Hypocrea pallida is recognized as a species of Protocrea. It is closely related to P. farinosa, morphologically, phylogenetically and by habit. Protocrea illinoënsis is described here as the sister taxon of P. farinosa found in the USA. All species are polyporicolous, with the principal hosts Skeletocutis nivea for P. farinosa and P. illinoënsis, and species of Oligoporus/Tyromyces for P. pallida. In addition to hosts the main differences among these species are a stronger (orange) pigmentation of perithecia and subiculum in P. pallida and a violaceous KOH reaction in P. pallida and P. illinoënsis. P. farinosa is known only from Europe with certainty and P. illinoënsis only from the USA, while P. pallida is probably cosmopolitan. Putative synonymy of some similar species is discussed.

The complete mitochondrial genome of Trichoderma simmonsii (Hypocreales: Hypocreaceae) from the Southern Coast of Korea.

Project description:Fungal species in the genus Trichoderma are widely used for industrial enzyme production and as biocontrol agents. In this study, we report the complete mitochondrial genome of a marine-derived Trichoderma simmonsii strain GH-Sj1, which belongs to the Harzianum clade of Trichoderma. GH-Sj1 was isolated from an edible sea alga Saccharina japonica collected from the southern coast of Korea. This newly assembled circular molecule is 28,668 bp in length and consists of 15 protein-coding genes, 26 transfer RNA genes, and two ribosomal RNA genes. Phylogenetic analysis using the maximum likelihood method shows that T. simmonsii GH-Sj1 is closely related to Trichoderma harzianum and Trichoderma lixii. To the best of our knowledge, this is the first characterization of a marine-derived mitogenome within the genus Trichoderma.

Three new species of soil-inhabiting Trichoderma from southwest China.

Project description:Fungi in the genus Trichoderma are widely distributed in China, including in Yunnan province. In this study, we report three new soil-inhabiting species in Trichoderma, named as T.kunmingense, T.speciosum and T.zeloharzianum. Their colony and mycelial morphology, including features of asexual states, were described. For each species, their DNA sequences were obtained from three loci, the internal transcribed spacer (ITS) regions of the ribosomal DNA, the translation elongation factor 1-α encoding gene (tef1) and the gene encoding the second largest nuclear RNA polymerase subunit (rpb2). Our analyses indicated that the three new species showed consistent divergence amongst each other and from other known and closely related species. Amongst the three, T.speciosum and T.kunmingense belong to the Viride Clade. Specifically, T.speciosum is related to three species - T.hispanicum, T.samuelsii and T.junci and is characterised by tree-like conidiophores, generally paired branches, curved terminal branches, spindly to fusiform phialides and subglobose to globose conidia. In contrast, T.kunmingense morphologically resembles T.asperellum and T.yunnanense and is distinguished by its pyramidal conidiophores, ampulliform to tapered phialides, discrete branches and ovoidal, occasionally ellipsoid, smooth-walled conidia. The third new species, T.zeloharzianum, is a new member of the Harzianum Clade and is closely associated with T.harzianum, T.lixii and T.simmonsii but distinguished from them by having smaller, subglobose to globose, thin-walled conidia.

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

Project description: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.
