Abstract Digitodesmium is a genus of saprobic fungi, generally associated with decaying wood in freshwater habitats or in the soil. As morphologic markers they produce cheiroid, euseptate conidia on sporodochia. During an exam of a necrotic robusta coffee stem sent from Nova Venécia, state of Espírito Santo, to the Plant Clinic at the Universidade Federal de Viçosa (Brazil), for disease diagnosis a fungus, recognized as having the typical features of Digitodesmium was observed. The fungus was isolated in pure culture and DNA was extracted. Sequences of the partial 18S ribosomal RNA gene, large subunit of the nrDNA, internal transcribed spacer and translation elongation factor 1-α were generated. The combination of results of the phylogenetic analysis with the exam of the morphology led to the conclusion that the fungus from coffee stem morphological data showed that this fungus represents a monophyletic distinct lineage within Digitodesmium and an undescribed species for the genus. The concatenate tree also revealed that Digitodesmium is divided in two distinct clades. The novel species can be differentiated morphologically from other species of Digitodesmium by the size of the conidia, the number of arms and the presence of appendages. The new species Digitodesmium polybrachiatum is hence proposed herein. A comparative table of conidial morphology for the species in the genus is also included.

Abstract Absidia is ubiquitous and plays an important role in medicine and biotechnology. In the present study, nine new species were described from China in the genus Absidia, i.e. A. ampullacea, A. brunnea, A. chinensis, A. cinerea, A. digitata, A. oblongispora, A. sympodialis, A. varians, and A. virescens. Besides, two varieties A. cylindrospora var. nigra and A. spinosa var. biappendiculata were elevated to a specific rank as A. nigra comb. nov. and A. biappendiculata comb. nov., respectively. These new taxa were proposed based on a comprehensive investigation of morphological traits (such as shape and size of sporangia, sporangiospores and projections on columellae), physiological feature (maximum growth temperatures), and multi-locus sequences (including internal transcribed spacer, large subunit D1-D2 domains of nuclear ribosomal DNA, partial translation elongation factor 1 alpha gene and actin gene). All species mentioned above are illustrated, and an identification key to all the known species of Absidia in China is included.

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

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.

Moelleriella sinensis, a fungal pathogen infecting whitefly nymphs (Hemiptera), is described and illustrated as a new species from Wu Yi Mountain in Fujian province, southeastern China. This species is characterized by producing a pale brown spore mass around whitish to pale yellow pulvinate stroma. In surveys of entomopathogenic fungal diversity, only the anamorphic state was found in collected stroma. Phylogenetic analyses using the nucleotide sequences derived from the nuclear ribosomal large subunit rRNA gene, RNA polymerase subunit 1, and translation elongation factor 1α, coupled to morphological characterization supports the placement of the isolate as a new species in a distinct lineage within Moelleriella.

Escovopsis (Ascomycota: Hypocreales, Hypocreaceae) is the only known parasite of the mutualistic fungi cultivated by fungus-growing ants (Formicidae: Myrmicinae: Attini: Attina, the “attines”). Despite its ecological role, the taxonomy and systematics of Escovopsis have been poorly addressed. Here, based on morphological and phylogenetic analyses with three molecular markers (internal transcribed spacer, large subunit ribosomal RNA and the translation elongation factor 1-alpha), we describe Escovopsisclavatus and E.multiformis as new species isolated from fungus gardens of Apterostigma ant species. Our analysis shows that E.clavatus and E.multiformis belong to the most derived Escovopsis clade, whose main character is the presence of conidiophores with vesicles. Nevertheless, the most outstanding feature of both new species is the presence of a swollen region in the central hypha of the conidiophore named swollen cell, which is absent in all previously described Escovopsis species. The less derived Escovopsis clades lack vesicles and their phylogenetic position within the Hypocreaceae still remains unclear. Considering the high genetic diversity in Escovopsis, the description of these new species adds barely two pieces to a huge taxonomic puzzle; however, this discovery is an important piece for building the systematics of this group of fungi.

Species of the genus Retiboletus in China were investigated based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU) and the translation elongation factor 1-α gene (TEF1-α). Nine species were recovered from China, including two new and seven known species. The new species, namely Retiboletus ater and R. sinogriseus, from southwestern and northeastern China respectively, are documented and illustrated in this paper. Retiboletus ater is morphologically characterized by its black to grayish black pileus, white to grayish hymenophore, black to blackish stipe and white to grayish white context. Retiboletus sinogriseus is morphologically characterized by its brown to grayish-brown pileus, yellow to grayish-yellow hymenophore, pale yellow to brownish stipe and yellow to brownish-yellow context. Descriptions and line drawings of these two novel species and their comparisons with allied taxa are presented.

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.

Boletellus and Heimioporus, two genera of Boletaceae with ornamented basidiospores, are shown to be distinct genera on the basis of phylogenetic analyses of nuclear ribosomal large-subunit and translation elongation-factor 1α DNA sequences. Comparison of spore ornamentation type – longitudinally ribbed in Boletellus v. punctate, alveolate-reticulate in Heimioporus – are further evidence for distinction. Analyses of multiple accessions from the Americas, Asia and Australia support the monophyly of Heimioporus and a ‘core Boletellus’ clade, containing the type species, B. ananas (M.A.Curt.) Murrill, and approximately seven additional species. Tests of alternative phylogenetic topologies could not reject monophyly of a more inclusive group containing the core Boletellus clade and six other species. Heimioporus australis Fechner & Halling, H. cooloolae Fechner & Halling, Boletellus deceptivus Halling & Fechner, B. reminiscens Halling & Fechner and B. sinapipes Fechner, K.Syme, R.Rob. & Halling are described as new species. Phylogenetic analyses also support the following new combinations: Aureoboletus projectellus (Murrill) Halling, A. mirabilis (Murrill) Halling, Hemileccinum subglabripes (Peck) Halling and the new name, Xerocomus tenax Nuhn & Halling.

Abstract The genus Neoconidiobolus was recently established to accommodate all members of the Conidiobolus subgenus Conidiobolus. Based on mitochondrial small subunit (mtSSU), nuclear large subunit (nucLSU) of rDNA and translation elongation factor 1-alpha (TEF1), this study further resolved the genus Neoconidiobolus into three clades, with three new taxa being added. They are N. kunyushanensis B. Huang & Y. Nie, sp. nov., N. lamprauges (Drechsler) B. Huang & Y. Nie, comb. nov., and N. nanodes (Drechsler) B. Huang & Y. Nie, comb. nov. Meanwhile, a morphologial comparison among species in the three clades and a key to the species of the genus Neoconidiobolus are provided herein.

Helvella species are ascomycetous macrofungi with saddle-shaped or cupulate apothecia. They are distributed worldwide and play an important ecological role as ectomycorrhizal symbionts. A recent multi-locus phylogenetic study of the genus suggested that the cupulate group of Helvella was in need of comprehensive revision. In this study, all the specimens of cupulate Helvella sensu lato with ribbed stipes deposited in HMAS were examined morphologically and molecularly. A four-locus phylogeny was reconstructed using partial sequences of the heat shock protein 90, nuclear rDNA internal transcribed spacer region 2, nuclear large subunit ribosomal DNA and translation elongation factor 1-α genes. Three clades were revealed in Helvella sensu stricto. Twenty species were included in the analysis, of which 13 are distributed in China. Three new species, H. acetabuloides, H. sichuanensis and H. tianshanensis, are described and illustrated in detail. A neotype was designated for H. taiyuanensis. Helvella calycina is a new record for China, while Dissingia leucomelaena should be excluded from Chinese mycota. Hsp90 and ITS2 are recommended as useful supplementary barcodes for species identifications of the genus.
