Two New Species

Fibrodontia is a genus of wood-inhabiting fungi consisting of four species so far, including F. gossypina as generic type. Two new species, Fibrodontia austrosinensis and F. subalba, are described and illustrated from China. Fibrodontia austrosinensis from southwestern China is characterized by a grandinioid to odontioid hymenophore with numerous small aculei, a dimitic hyphal system with scattered, smooth skeletal hyphae and ellipsoid basidiospores measuring 4.2–5.2 × 3.5–4.5 μm. Fibrodontia subalba from the West Tianshan Mountain in northwestern China is distinguished by an odontioid to hydnoid hymenophore, a dimitic hyphal system, and ellipsoid basidiospores measuring 3.7–4.4 × 2.8–3.4 μm. The phylogenies inferred from the data set of nuc rDNA ITS1-5.8S-ITS2 (ITS) and D1–D2 domains of nuc 28S rDNA (28S), and that of ITS, 28S, translation elongation factor (tef1α), and RNA polymerase II second largest subunit (rpb2) supported Fibrodontia as a monophyletic genus in the Trechisporales, and F. austrosinensis and F. subalba as separate lineages within Fibrodontia. Multi-rate Poisson Tree Processes, Automatic Barcode Gap Discovery and genetic distance methods based on ITS sequences of Fibrodontia also supported F. austrosinensis and F. subalba as distinct species. The taxonomic status of F. fimbriata that was recently transferred from Cystidiodendron, is briefly discussed. A key to all six known species of Fibrodontia is provided.

Abstract Two new species of Amanita sect. Roanokenses (Amanitaceae, Agaricales, Basidiomycota), Amanita alboradicata and A. fulvopyramis are proposed here on morphological and molecular evidence. The described and illustrated are based on morphological studies of collections from Jilin, Zhejiang and Hunan provinces in China. Nuclear ribosomal large subunit (nrLSU), RNA polymerase II second largest subunit (rpb2) and translation elongation factor 1-α (tef1-α) sequences analyses supported establishment of these two new species and revealed their phylogenetic positions. Both new species possess long radicating basal bulbs. Amanita alboradicata is characterized by a white or dirty white pileus covered with angular warts. Amanita fulvopyramis is characterized by the brown orange to light brown, pyramidal to verrucose volval remnants on the pileus, and light brown to brown lamellae. Holotypes are deposited in the Mycological Herbarium of Hunan Normal University.

Ganoderma dianzhongensesp. nov. and G. esculentumsp. nov. are proposed as two new species based on both phenotypic and genotypic evidences. Ganoderma dianzhongense is characterized by the stipitate basidiomata, laccate and oxblood red pileus, gray white pore surface, duplex context and broadly ellipsoid basidiospores (9.0–12.5 × 6.5–9.0 μm) with coarse interwall pillars. Ganoderma esculentum is characterized by its basidiomata with slender stipe, white pore surface, homogeneous pileus context, and slightly truncate, narrow basidiospores (8.0–12.5 × 5.0–8.0 µm). Phylogenetic analyses were carried out based on the internal transcribed spacer (ITS), translation elongation factor 1-α (TEF1-α) and the second subunit of RNA polymerase II (RPB2) sequence data. The illustrations and descriptions for the new taxa are provided.

A New Species

A new species, Cantharellus albus, was collected from southwestern China and described with both morphological and molecular characters. It differs from other species of Cantharellus by its smooth white pileus, white hymenophore, and white stipe, the latter turning yellow after bruising. The phylogenetic tree inferred from the combined dataset of three DNA fragments, namely large subunit ribosomal RNA gene (LSU), RNA polymerase II second largest subunit (rpb2), and translation elongation factor 1-alpha gene (tef1), indicated that the new species is distinct from other species of Cantharellus and is a member of sect. Flavobrunnei within the subgenus Parvocantharellus.

Abstract More than 200 recent collections of Trichoderma from China were examined and 16 species belonging to the Viride clade were identified based on integrated studies of phenotypic and molecular data. Among them, seven wood-inhabiting new species, T. albofulvopsis, T. densum, T. laevisporum, T. sinokoningii, T. sparsum, T. sphaerosporum and T. subviride, are found. They form trichoderma- to verticillium-like conidiophores, lageniform to subulate phialides and globose to ellipsoidal conidia, but vary greatly in colony features, growth rates, and sizes of phialides and conidia. To explore their taxonomic positions, the phylogenetic tree including all the known species of the Viride clade is constructed based on sequence analyses of the combined RNA polymerase II subunit b and translation elongation factor 1 alpha exon genes. Our results indicated that the seven new species were well-located in the Koningii, Rogersonii and Neorufum subclades as well as a few independent terminal branches. They are clearly distinguishable from any existing species. Morphological distinctions and sequence divergences between the new species and their close relatives were discussed.

Medicinal Properties

Ganoderma is a cosmopolitan white rot fungal genus, famous for its medicinal properties. In the present study, two new Ganoderma species were collected from south-eastern China and described on the basis of morphological characters and phylogenetic analyses of sequences of the internal transcribed spacer (ITS) region, the translation elongation factor 1-α gene (EF1-α) and the second subunit of RNA polymerase II (RPB2). Specimens of both species were found on living trees of Casuarinaequisetifolia. Ganodermaangustisporum sp. nov. is characterised by its sessile basidiomata and almond-shaped, slightly truncate, narrow basidiospores (9–11.3 × 4–5.2 µm). Ganodermacasuarinicola sp. nov. is characterised by its strongly laccate reddish-brown pileal surface, luminous yellow to yellowish-brown cutis and ellipsoid, truncate basidiospores (9–10.2 × 5–6 µm). The two new species are compared with their related taxa. Phylogenetic analyses confirmed that G.angustisporum and G.casuarinicola are distinct species within Ganoderma.

Two New Species

A new genus and eight new species, all with isaria-like phialides, are described in Cordycipitaceae from Thailand. The new genus, Samsoniella, is segregated from Akanthomyces based on morphological and molecular evidence. Samsoniella differs from Akanthomyces in producing orange cylindrical to clavate stromata with superficial perithecia and orange conidiophores with isaria-like phialides and white to cream conidia. A new combination for CBS 240.32, originally identified as Paecilomyces farinosus (Isaria farinosa), and CBS 262.58, originally identified as Penicillium alboaurantium, respectively, is made in Samsoniella. Two new species, Samsoniella aurantia and S. inthanonensis, are described from lepidopteran larvae. Two new species of Cordyceps, C. blackwelliae and C. lepidopterorum, were also found on coleopteran and lepidopteran larvae. Both produce isaria-like morphs with globose phialides and attenuated long necks and white mycelium in culture. The authors established a sexual-asexual link for Cordyceps javanica (= Isaria javanica) on lepidopteran larvae. Four new species, Akanthomyces kanyawimiae, A. sulphureus, A. thailandicus, and A. waltergamsii, were pathogenic on spiders, with some strains of A. kanyawimiae also found on unidentified insect larvae. These four species of Akanthomyces occur on the underside of leaves and produce white to cream white powdery conidia, whereas S. aurantia and S. inthanonensis were found in leaf litter and produce bright orange stromata and synnemata with white conidia. Another new combination, Akanthomyces ryukyuensis, is proposed. Phylogenetic analyses based on a combined data set comprising the nuc rDNA region encompassing the internal transcribed spacers 1 and 2 along with the 5.8S rDNA (ITS), nuc 28S rDNA (28S), partial sequences of translation elongation factor 1-α gene (TEF1), and the genes for RNA polymerase II largest (RPB1) and second-largest (RPB2) subunits strongly support the delimitation of these new species of Cordyceps, Akanthomyces, and in a new genus Samsoniella in Cordycipitaceae.

Among 240 specimens of Trichoderma producing sexual states collected in different regions of China, 80 specimens representing 21 species possess green ascospores. Species were identified based on integrated studies of phenotypic features, culture characteristics and molecular analyses of RNA polymerase II subunit b and translation elongation factor 1-α genes. Of these 21 species, seven are recognized here as new: T. angustum, T. crystalligenum, T. globoides, T. perviride, T. purpureum, T. tenue and T. viridulum. Trichoderma angustum and T. crystalligenum belong to the Strictipile clade, and the remaining five species are in the Harzianum clade. Trichoderma angustum inhabits herbaceous stems and possesses trichoderma- to verticillium-like conidiophores. Trichoderma crystalligenum forms brownish yellow pulvinate stromata, pachybasium-like conidiophores, and abundant yellow crystals in culture. Trichoderma globoides and T. perviride share a common ancestor with but are different from T. alni, T. christiani, T. corneum and T. italicum. Trichoderma purpureum is a sister of T. epimyces, and is distinguished by its purplish red stromata. Trichoderma tenue is closely related to T. priciliae and T. rufobrunneum, and is characterized by verticillium-like conidiophores and slender phialides. Trichoderma viridulum is associated with T. cerinum, T. tomentosum and T. ceraceum; it is distinguishable by trichoderma-like rather than pachybasium-like conidiophores. Morphological distinctions between the new species and their allies are discussed. This study updates our knowledge of species diversity of the group.

A New Species

Abstract Fungal species belonging to the genus Balansia (Clavicipitaceae) are well known as endophytic and epibiotic species commonly found on grasses or sedges. Among the 36 species of Balansia described worldwide, ten have been reported in Brazil. While most species of balansoid fungi were described on graminaceous plants, only four were characterized on cyperaceous hosts. To correctly identify the species of balansoid fungi associated with Scleria bracteata (Cyperaceae), specimens were collected in the state of Alagoas, Brazil, in 2014 and 2016. Nucleotide partial sequences of the second-largest subunit of RNA polymerase II (RPB2), translation elongation factor 1-α (TEF1), 18S subunit ribosomal DNA (SSU), 28S subunit ribosomal DNA (LSU), and internal transcribed spacers (ITS) were obtained from each balansoid specimen. Based on morphology and molecular data, the specimens were identified as a putative new species of Balansia, herein referred to as Balansia scleriae sp. nov.

Two New Species

A taxonomic re-evaluation of the cosmopolitan fish species Atractoscion aequidens (Cuvier 1830) revealed that it comprises several distinct species occurring in different oceans. Here we describe two new species, Atractoscion macrolepis sp. nov. and Atractoscion microlepis sp. nov., based on specimens collected from Angola and Oman, respectively, and we resurrect the species Atractoscion atelodus (Günther 1867), from Australia. Morphological comparison of A. aequidens from South Africa (type locality) with species from geographically distant localities showed that they differed in the mode number of lateral line pored scales (76 for A. aequidens; 73 for A. macrolepis sp. nov.; 78 for A. microlepis sp. nov.) and the number of dorsal-fin soft rays (26–29 for A. aequidens; 31–33 or 34 for A. atelodus; 24–28 for A. macrolepis sp. nov.; 25–26 for A. microlepis sp. nov.). Comparison of 506 bp sequences in mitochondrial DNA cytochrome c oxidase subunit I showed that the Kimura 2-parameter distance for A. aequidens differs substantially from that for the other species (5.1–5.3% different from A. atelodus; 3.7–4.4 from A. macrolepis sp. nov.; 4.8–5.0 from A. microlepis sp. nov.). The study highlights that DNA barcoding can contribute to confirming the taxonomic status of geographic variations.

Diaporthe species include important plant pathogenic fungi with extensive host ranges and geographic distributions. In the present study, two new species of Diaporthe causing diebacks from southern China are described and illustrated. Isolates were characterized morphologically and assigned to species based on multigene sequence analyses. Phylogenetic analysis based on the internal transcribed spacer (ITS) region, calmodulin (CAL), histone H3 (HIS), translation elongation factor 1-alpha (TEF1-α) and beta-tubulin (TUB) region grouped isolates into two distinct lineages. Within each linage these species appear to be unique and are described as D. sennae sp. nov and D. sennicola sp. nov, and their relationships with other species in the genus are indicated.
