Abstract

This is the first in a series of papers on lignicolous freshwater fungi from China. In this paper, eight fresh collections of taxa of Dictyosporiaceae from submerged wood in freshwater are characterized based on morphological characters and phylogenetic analyses of combined ITS, LSU and TEF1α sequence data. A new monotypic genus Aquadictyospora, with A. lignicola as the type species is introduced based on its distinct morphology and evidences from molecular phylogeny. In addition, detailed description and illustration of Pseudodictyosporium wauense from the fresh collection are provided and it is a new record for China.

Abstract

We collected six “tar spot” disease specimens from various hosts and these were subjected to morpho-phylogenetic studies. In this paper, a new genus, Neophyllachora is introduced to accommodate N. cerradensis, N. myrciae, N. myrciariae, N. subcircinans and N. trucantispora, which are related to Phyllachora species but constitutes an independent strongly supported monophyletic clade within Phyllachoraceae of the Phyllachorales. Three novel Phyllachora species; P. chloridis, P. cynodonticola and P. panicicola on Poaceae are also introduced. Phenotypic comparisons and phylogenetic analysis of partial SSU, LSU and ITS sequence data with homologous taxa, confirm the placement of the novel species in Phyllachoraceae. The family Polystigmataceae is re-established to accommodate Polystigma within the order Xylariales. The asexual morph of Polystigma rubrum was re-collected from Russia and is provided as a reference specimen with a description, illustrations and molecular data. Further studies with multiple gene analysis are recommended to provide a natural and stable classification system for members of Phyllachorales.

Abstract

Eurotium cristatum is the main probiotic fungus involved in fermentation of Chinese Fuzhuan brick tea, and the amount of E. cristatum is an important indicator of tea quality. Sexual development of E. cristatum consists of three main stages, hypha and ascogonium (at 36 hours post-inoculation), cleistothecium formation (at 48 hours), and cleistothecium ripening (at 72 hours), and each stage exhibits a unique metabolite profile. In this study, developmental changes were analyzed by GC–MS based untargeted metabolomics. Ninety-nine metabolites involved in multiple biochemical pathways were identified. Principal component analysis separated developing E. cristatum into 36, 48 and 72 hour groups. Hierarchical cluster analyses showed that the relative contents of organic acids and amino acids peaked at 36 hours and decreased thereafter, while alcohol and carbohydrate levels peaked at 48−72 hours. Statistical analysis revealed 401 significant metabolite−metabolite correlations (Pearson’s |r|>0.8 at a false discovery rate ≤ 0.05), of which 213 were positive and 188 negative. The early increases in organic acid and amino acid metabolites as well as certain phosphate and amine metabolites favor ascogonium formation. Conversely, increased alcohol and carbohydrate concentrations favor cleistothecium formation. These results provide a foundation for further exploration of the biochemical mechanism underlying sexual development in E. cristatum.

Abstract

Agaricus is a genus of macrofungi containing species with highly edible and medicinal values. A mushroom survey was recently carried out in Qilian Mountain National Natural Reserve, in Gansu Province of China, and yielded 21 Agaricus specimens. The morphological examination and phylogenetic analysis based on four-gene sequences from those specimens were conducted. The result shows they belong to four species in A. section Bivelares: A. sinotetrasporus sp. nov. and A. qilianensis sp. nov. are new species for science; A. devoniensis is a new record from China; and the famous button mushroom, A. bisporus is found in the wild. All of them are described and illustrated in details. A brief comparison with similar taxa or previous records are addressed too.

Abstract

The genus Ganoderma (Ganodermataceae) has a long history in traditional medicine to improve longevity and health in Asia. Ganoderma has been widely used in multiple therapeutic activities as well as dietary supplements to prevent and treat many diseases. Several classes of bioactive substances have been isolated and identified from Ganoderma, such as polysaccharides, triterpenoids, nucleosides, sterols, fatty acids, protein and alkaloids. There are numerous research publications, which report the abundance and variety of biological actions initiated by the metabolites of Ganoderma. Investigation on different metabolic activities of Ganoderma species has been performed both in vitro and in vivo. In many cases, however, it has been questioned whether Ganoderma is solely a nourishment supplement for wellbeing or merely a helpful "medication" for restorative purposes. There has been no any conclusive report of human trials using Ganoderma species as a direct control agent for diseases. In addition, there is no evidence supporting the usage of Ganoderma species (excluding G. lucidum) as potential supplements for cancer or other diseases in humans since no preclinical trials have been performed up to date. In this review, the beneficial medicinal properties of several species of Ganoderma (excluding G. lucidum) and their secondary metabolites are discussed. Ganoderma species can be used as a therapeutic drug, but more direct scientific evidence should be made available in the future. The efficiency of Ganoderma in clinical treatments should be substantiated with more biomedical research and their true impact assessed on human health with more standardized clinical evaluations so that the feasibility of biologically active extracts of Ganoderma species in alternative treatments can be recommended.
