Calonectria vigiensis sp. nov. (Hypocreales, Nectriaceae) is a newly described species associated with cacao (Theobroma cacao L.) in Mérida state, Venezuela. This new species was identified using morphological methods as well as DNA sequencing and multigene phylogenetic analyses. Based on phylogenetic analyses of a combined dataset including translation elongation factor 1-α (tef1), calmodulin (cmdA), and β-tubulin (btub) genes across closely related species within Calonectria, a new species was identified as Ca. vigiensis within the Calonectria naviculata species complex, but it was determined to be well-separated from genetically close species such as Calonectria multilateralis L. Lombard & Crous, Calonectria multinaviculata R.F. Alfenas, L. Lombard & Crous, and Calonectria naviculata Crous & M.J. Wingf. This work reports 1 previously undescribed fungal species (Ca. vigiensis) that is associated with dieback and sudden-death symptoms in T. cacao plantations in Mérida state, Venezuela.

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.

During an exploration of plant pathogens in vegetables occuring in Zhejiang province, China, a novel fungal species, was found. Three strains ZJUP0033-4, ZJUP0038-3 and ZJUP0132 were isolated from black round lesions in the stems and leaves of Amaranthus sp. Phylogenetic analyses based on sequences from four genes including rDNA internal transcribed spacer (ITS), translation elongation factor 1-α (EF1-α), histone (HIS) and β-tubulin (TUB) indicated that D. sinensis clustered in a distinct clade closely related to D. neoarctii, D. angelicae, D. subordinaria, D. arctii, D. cuppatea, D. lusitanicae, D. novem, D. infecunda, D. ganjae and D. manihotia. Morphologically, D. sinensis is distinguished by brown, scattered, globose pycnidia and ellipsoid alpha conidia with bi- to multiguttulate.

A New Species

In this paper we describe a new species of cave fungus belonging to Sporocadaceae (Amphisphaeriales), collected from Gem Cave, Fumin County, Yunnan Province, China. Initial morphological observations confirmed that our fungal collection is a pestalotioid species. Phylogenetic analyses of combined internal transcribed spacer (ITS), β-tubulin (TUB) and translation elongation factor 1-alpha (TEF1α) gene sequence dataset confirmed that our fungus forms an independent branch within Neopestalotiopsis. Thus, we describe our fungus as a new species of Neopestalotiopsis based on both morphology and multigene phylogeny. This is the first-ever report of Neopestalotiopsis from a cave habitat. A full description, micrographs and a phylogenetic tree showing the placement of the new species are provided.

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.

Macadamia (Macadamia integrifolia) is native to eastern Australia and produces an edible nut that is extensively cultivated in commercial orchards in several countries. Little is known about the diversity of fungi associated with diseases of macadamia inflorescences. A survey of fungi associated with the dry flower disease of macadamia detected several isolates of Neopestalotiopsis (Pestalotiopsidaceae, Sordariomycetes). Five new species of Neopestalotiopsis were identified based on molecular phylogenetic analyses of concatenated gene sequences of the internal transcribed spacer (ITS), β-tubulin (TUB), and the translation elongation factor 1-alpha (TEF1α). The new species are named Neopestalotiopsis drenthii, N. maddoxii, N. olumideae, N. vheenae, and N. zakeelii, and are described by molecular, morphological, and cultural characteristics. The ecology of the isolates and their pathogenic, saprophytic, or commensal ability were not determined.

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

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.

Trichoderma is an important genus of family Hypocreaceae, which contain nearly 375 known species. In current study, a new species Trichoderma dumbbelliforme collected from virgin forest soil of Nagaland and confirmed based on morphological and phylogenetic analyses. Morphologically, T. dumbbelliforme sp. nov. distinguished from other species of Trichoderma by producing nodules on sterile part of the conidiophores and pyriform to dumbbell shaped conidia with the size of 4.0–6.0×2.5–3.0µm and having two big guttulae at each end. Furthermore, the fungus was confirmed by molecular characterization using Translation elongation factor 1-α (tef-1) gene sequencing.  The phylogenetic relationship was established for generated sequence and many related ex-type sequences downloaded from NCBI GenBank by maximum-parsimony analysis. Tef-1 sequence data clarified the phylogenetic affinity to clade-1 of Trichoderma as per new authoritative guide line on molecular identification of Trichoderma. Phylogenetically, this new species of Trichoderma closely related to T. crassum, T. spirale, T. sulawesense, T. longisporum, T. virens, T. gelatinosum and T. gliocladium species. Therefore, the morphological comparisons were done with closely related species viz., T. crassum and T. spirale which lead to the conclusion that the collected taxon is new to science.

A new species of endophytic fungi, Trichoderma polyalthiae, was isolated from stems of Polyalthia debilis in Ubon Ratchatani Province, Thailand. Trichoderma polyalthiae was distinguished from closely related species by its molecular and phenotypic characteristics. Based on multigene phylogenetic analyses of the internal transcribed spacer region, translation elongation factor 1-α, and RNA polymerase subunit II gene sequences, T. polyalthiae formed a distinct clade. Morphologically, T. polyalthiae can be distinguished from closely related taxa by its growth rates, diffusing of pigment into agar, and hyaline conidia and production of chlamydospores.
