Three new species of Talaromyces sect. Talaromyces discovered from soil in China.

ABSTRACT: Three new Talaromyces species isolated from soil are reported here, namely T. dimorphus (ex-type strain AS3.15692 T), T. lentulus (ex-type strain AS3.15689 T) and T. mae (ex-type strain AS3.15690 T). T. dimorphus is characterized by biverticillate and monoverticillate penicilli, ampulliform phialides, slimy texture with sparse mycelial funicles and absent conidiogenesis on MEA. T. lentulus is featured by vivid yellow mycelium on Cz and MEA, absent conidiogenesis on CYA, and globose smooth-walled conidia. T. mae presents sparse conidia on CYA and YES, funiculous and floccose texture on MEA, and ovoid smooth-walled conidia. Both morphological and molecular characters show that T. dimorphus is unique and has no close relatives. Although T. lentulus and T. mae resembles T. adpressus and T. pinophilus very much, phylogenetic analyses of CaM, BenA, ITS and Rpb2 sequences all support their status as novel species.

Two New Sexual Talaromyces Species Discovered in Estuary Soil in China.

Project description:In the survey of mycobiota of mudflats in China, two new sexually reproducing Talaromyces sect. Talaromyces species were discovered and studied using a polyphasic approach. These species are named here Talaromyces haitouensis (ex-type AS3.160101T) and Talaromyces zhenhaiensis (ex-type AS3.16102T). Morphologically, T. haitouensis is distinguished by moderate growth, green-yellow gymnothecia, orange-brown mycelium, and echinulate ellipsoidal ascospores. T. zhenhaiensis is characterized by fast growth, absence of sporulation, cream yellow to naphthalene yellow gymnothecia and mycelium, and smooth-walled ellipsoidal ascospores with one equatorial ridge. The two novelties are further confirmed by phylogenetic analyses based on either individual sequences of BenA, CaM, Rpb2, and ITS1-5.8S-ITS2 or the concatenated BenA-CaM-Rpb2 sequences.

Three new Dioszegia species (Bulleribasidiaceae, Tremellales) discovered in the phylloplane in China.

Project description:The genus Dioszegia is comprised of anamorphic basidiomycetous yeasts and is classified in the family Bulleribasidiaceae of the order Tremellales. Currently, 24 species have been described and accepted as members of the genus, although its diversity and global distribution have not been thoroughly investigated. In this study, yeasts were isolated from plant leaves collected in the Guizhou and Henan Provinces of China and identified through a combination of morphological and molecular methods. Phylogenetic analyses of the combined ITS and LSU sequences coupled with morphological studies revealed three novel species, D.guizhouensissp. nov., D.foliicolasp. nov., and D.aurantiasp. nov., proposed here. Additionally, our phylogenetic analyses suggest that the recently discovered species D.terrae is a synonym of D.maotaiensis. This study presents detailed descriptions and illustrations of three new Dioszegia species and highlights distinctions between them and their close relatives. The findings of this study contribute to our knowledge of the biodiversity of Dioszegia, offering a foundation for future research.

New Talaromyces species from indoor environments in China.

Project description:Talaromyces contains both asexual and sexually reproducing species. This genus is divided in seven sections and currently has 105 accepted species. In this study we investigated the Talaromyces isolates that were obtained during a study of indoor air collected in Beijing, China. These indoor Talaromyces strains are resolved in four sections, seven of them are identified as T. islandicus, T. aurantiacus, T. siamensis and T. albobiverticillius according to BenA sequences, while 14 isolates have divergent sequences and are described here as nine new species. The new species are placed in four sections, namely sections Helici, Islandici, Talaromyces and Trachyspermi. They are described based on sequence data (ITS, BenA, CaM and RPB2) in combination with phenotypic and extrolite characters. Morphological descriptions and notes for distinguishing similar species are provided for each new species. The recently described T. rubrifaciens is synonymised with T. albobiverticillius based on presented phylogenetic results.

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.

New Species of Talaromyces (Trichocomaceae, Eurotiales) from Southwestern China.

Project description:Species of Talaromyces are cosmopolitan and ubiquitous, and some are of industrial and medicinal importance. Species of Talaromyces have been successively reported in China. During our examinations of samples collected from southwestern China, two new species belonging to Talaromyces sect. Talaromyces were further discovered based on phylogenetic analyses and morphological comparisons. Talaromyces ginkgonis sp. nov., isolated from a partially colonized fruit of Ginkgo biloba, differs from closely-related fungi in the combination of conidia ellipsoidal, smooth and 3.5-4 × 2-3 μm, no growth on CYA at 37 °C and sequence divergences; T. shilinensis sp. nov. is distinguished from its related allies in the combination of smooth conidia, colonies 10-11 mm diameter on CYA at 25 °C and sequence differences. Detailed descriptions and illustrations of the new taxa are given.

Three Pairs of New Isopentenyl Dibenzo[b,e]oxepinone Enantiomers from Talaromyces flavus, a Wetland Soil-Derived Fungus.

Project description:Three pairs of new isopentenyl dibenzo[b,e]oxepinone enantiomers, (+)-(5S)-arugosin K (1a), (-)-(5R)-arugosin K (1b), (+)-(5S)-arugosin L (2a), (-)-(5R)-arugosin L (2b), (+)-(5S)-arugosin M (3a), (-)-(5R)-arugosin M (3b), and a new isopentenyl dibenzo[b,e]oxepinone, arugosin N (4), were isolated from a wetland soil-derived fungus Talaromyces flavus, along with two known biosynthetically-related compounds 5 and 6. Among them, arugosin N (4) and 1,6,10-trihydroxy-8-methyl-2-(3-methyl-2-butenyl)-dibenz[b,e]oxepin-11(6H)-one (CAS: 160585-91-1, 5) were obtained as the tautomeric mixtures. The structures of isolated compounds were determined by detailed spectroscopic analysis. In addition, the absolute configurations of these three pairs of new enantiomers were determined by quantum chemical ECD calculations.
