A New Species

Phellinus vietnamensis sp. nov. is described from Vietnam based on morphological characters and molecular data. Morphologically, it is characterized by perennial, pileate basidiomata, a dimitic hyphal system, hooked hymenial setae, and colorless, broadly subglobose to ovoid, thick-walled basidiospores 5.5–6 × 4.8–5.2 μm. Phylogenetically, the status of Phellinus vietnamensis is strongly supported based on sequences of the nuclear internal transcribed spacer (ITS) regions, the translation elongation factor 1-α gene (EF1-α) nuclear large subunit rDNA (nrLSU) and the second largest subunits of RNA polymerase II (RPB2).

A New Species

Heimioporus sinensis, collected from tropical and subtropical areas of China, is introduced as a new species based on both morphological characters and molecular data. The species is characterized by the purplish red to deep magenta pileus, the reticulated stipe, the irregularly reticulate to reticulate-alveolate basidiospores 11.5–13.5 × 8–9.5 μm, and a trichodermal to intricately trichodermal pileipellis. Phylogenetic analyses based on the nuc 28S rDNA D1-D2 domains (28S) and the translation elongation factor 1-α gene (tef1-α) showed that H. sinensis is a distinct member of the genus Heimioporus in the subfamily Xerocomoideae.

A New Species

Two lineages of Aureoboletus (Boletales, Boletaceae) from southern China were revealed by using molecular data based on combined dataset of the nuclear ribosomal large subunit RNA (nrLSU), the translation elongation factor apha-1 (tef1-a) and the largest subunit of RNA polymerase II (rpb1). One of them corresponds with the previous morphology-based taxon, viz. Boletellus longicollis, another one is different from those taxa described based on morphological features. And, thus, Auroboletus clavatus sp. nov. and A. longicollis comb. nov. were proposed. A detailed description, colour photos of fresh basidiomata, and a line-drawing of microscopic features of the two taxa were provided.

Three species of Lepiota sensu lato from China are described and illustrated based on morphological characters and molecular evidence. Echinoderma flavidoasperum and Lepiota omninoflava are new to science, while Lepiota echinacea is newly reported from China. Echinoderma flavidoasperum is characterized by a yellow pileus, nearly smooth stipe that discolors light red when bruised, and subcylindrical basidiospores. Lepiota omninoflava, so far only found in the tropics, is characterized by the yellow basidiomata, ellipsoid basidiospores and the absence of cheilocystidia. All three of the Chinese species are discussed and placed within a phylogeny based on the internal transcribed spacer (ITS) region, the large subunit (LSU) of the ribosomal DNA, the translation elongation factor 1-α (tef1-α) and the second largest subunit of RNA polymerase II (rpb2).

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.

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.

Harrya is described as a new genus of Boletaceae to accommodate Boletus chromapes, a pink-capped bolete with a finely scabrous stipe adorned with pink scabers, a chrome yellow base and a reddish-brown spore deposit. Phylogenetic analyses of large-subunit rDNA and translation elongation factor 1α confirmed Harrya as a unique generic lineage with two species, one of which is newly described (H. atriceps). Some Chinese taxa were recently placed in a separate genus, Zangia, supported by both morphology and molecular data. Multiple accessions from Queensland, Australia, support the synonymy of at least three species in a separate Australian clade in the new genus, Australopilus. The truffle-like Royoungia is also supported as a separate lineage in this clade of boletes. Even though it lacks stipe characters, it possesses the deep, bright yellow to orange pigments in the peridium. Additional collections from Zambia and Thailand represent independent lineages of uncertain phylogenetic placement in the Chromapes complex, but sampling is insufficient for formal description of new species. Specimens from Java referable to Tylopilus pernanus appear to be a sister group of the Harrya lineage.

A new species, Amanita griseofusca in section Vaginatae is described and illustrated here from Pakistan. Distinguishing characters of the new species include medium-sized basidiomata, greyish brown pileus surface with white to beige, membranous volval remnants present as one (large) to a few (small) warts, close lamellae which are cream colored with a pink tone, striations one third of the total pileus radius, broadly ellipsoidal to ellipsoidal basidiospores and white loose saccate volva turning beige at maturity. Molecular data inferred from partial nuc rDNA internal transcribed spacer region (ITS), partial nuc rDNA larger subunit region (LSU) and partial translation elongation factor 1-alpha (tef1) confirms the novelty of the present taxon.

A new polypore, Rhodonia tianshanensis, collected from West Tianshan Nature Reserve in Xinjiang Autonomous Region (northwest China), is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by having resupinate basidiomata with an oblique tube layer, fusoid cystidioles in the hymenium, and cylindrical basidiospores. Based on multiple loci DNA sequences including the internal transcribed spacer (ITS), the large subunit (nLSU), and the second subunit of RNA polymerase II (RPB2) regions, our phylogeny strongly supported R. tianshanensis as a new species belonging to the genus Rhodonia.

The following three similar Amanita spp. are described: Amanita djarilmari E.M.Davison, A. gardneri E.M.Davison from the south-west of Western Australia and A. millsii E.M.Davison & G.M.Gates (=A. sp. 10 ZLY-2014 HKAS 77322 in KUN) from Tasmania. All have a white- or pale-coloured pileus and white universal veil, but differ in the shape of the bulb, spore shape, and structure of the universal veil. All are from subgenus Lepidella section Phalloideae. Phylogenetic analysis showed that these species cannot be separated on the basis of data derived from nuclear ribosomal internal transcribed-spacer sequences. They can be separated in a multi-locus phylogeny of the 28S nuclear ribosomal large-subunit rRNA region, RNA polymerase-II region, β-tubulin region and translation elongation-factor 1-α region. Amanita djarilmari, A. gardneri, A. millsii and two other previously described species in section Phalloideae from southern Australia (A. eucalypti and A. marmorata) cluster in Clade IX. These, together with other species in this clade, segregate into two lineages, namely, Clade IX A, with a white or pale pileus, and Clade IX B, with a brown pileus. Solvent extraction, followed by liquid-chromatography tandem-mass spectrometry of A. djarilmari, A. eucalypti, A. gardneri and A. marmorata basidiomes did not detect the highly toxic amatoxins α-amanitin and β-amanitin, but did detect the phallotoxins phallacidin and phalloidin.

A New Species

During an investigation of ascomycetous fungi in Karst formations of the Asian region, three interesting taxa were found on dead aerial stems of woody hosts in Guizhou province, China. Their morphology assigned them as typical botryosphaeriaceous species. Phylogenetic analyses based on a combined DNA dataset of large subunit (LSU), internal transcribed spacer (ITS) and part of the translation elongation factor 1-α (tef1) gene confirmed their placement within Botryosphaeriaceae. In the phylogenetic tree, the three isolates formed a well-supported monotypic clade as a distinct lineage within the genus Sardiniella. Therefore, a new species Sardiniella guizhouensis sp. nov. is introduced to accommodate these taxa and detailed, illustrated descriptions of the asexual and sexual morphs are provided. This study reveals the first sexual morph of Sardiniella, which it is characterized by 2–4(–6)-spored asci with hyaline to brown, aseptate to 1-septate, ovate to subclavate ascospores.
