Morphology and Molecular Phylogeny Reveal Five New Species of (Hydnangiaceae, Agaricales) from Southern China.

The genus is a type of cosmopolitan and ecologically important fungal group. Members can form ectomycorrhizal associations with numerous trees, and some species are common edible fungi in local markets. Although some new species from China are recently published, the species diversity of is still unclear in China.

Two highly conjugated ergosterols from the fungus and their anti-inflammatory activity.

Two previously undescribed ergosterols containing a highly conjugated ring system, psathrosterols A and B ( and ), have been isolated from the fungus . Their structures with absolute configurations were established by extensive spectroscopic methods, as well as single crystal X-ray diffraction. Compounds and showed inhibitory activity against NO production with IC values of 22.

New insights into the genus (Gyroporaceae, Boletales), with establishment of four new sections and description of five new species from China.

Species of from southern China were studied in this study. Based on morphology and molecular phylogenetic analyses of DNA sequences from the nuclear ribosomal internal transcribed spacer (ITS), the nuclear ribosomal large subunit (nrLSU), and the mitochondrial adenosine triphosphate ATP synthase subunit 6 ( was divided into four main branches in the phylogenetic tree, and four sections were firstly proposed i.e.

Diversity of (Cantharellales, Basidiomycota) in China with Description of Some New Species and New Records.

is a well-known genus of edible mushrooms, belonging to the family Hydnaceae in the class Agaricomycetes. In this study, a phylogenetic overview of subg. and C.

Two new species of (Phallaceae) with a white indusium from China.

Two new species, and were discovered in southwestern and southern China, respectively. is morphologically characterized by its cream to ochraceous receptacle, white to very slightly pinkish indusium, white to pinkish pseudostipe and white to slightly purplish pink volva. is characterized by a white to yellowish white receptacle, a strongly rigid indusium usually without serrated margin and smaller basidiospores than those of .

Two new (Inocybaceae) species with unexpected muscarine contents from tropical China.

An accurate identification of poisonous mushrooms and the confirmation of the toxins involved are both of great importance in the treatment of mushroom poisoning incidents. In recent years, cases of mushroom poisoning by spp. have been repeatedly reported from tropical Asia.

Multigene Phylogeny and Morphology Reveal Unexpectedly High Number of New Species of Subgenus (Hydnaceae, Cantharellales) in China.

The genus , commonly known as chanterelles, has recently been divided into six subgenera; however, wider sampling approaches are needed to clarify the relationships within and between these groups. A phylogenetic overview of subgenus in China was inferred based on the large subunit nuclear ribosomal RNA gene (nrLSU), the DNA-directed RNA polymerase II subunit 2 (2), and the transcription elongation factor 1-alpha (1). A total of nine species from China were assigned to the subgenus, including seven novel species, namely , , , , , , and , and two known species, namely and .

Transcriptome sequencing analysis of the MSDIN gene family encoding cyclic peptides in lethal Amanita fuligineoides.

Amanita fuligineoides, a lethal mushroom discovered in China, contains abundant cyclic peptide toxins that can cause fatal poisoning. However, the MSDIN gene family encoding for these cyclic peptides in A. fuligineoides has not been systematically studied.

, and in China.

Within the family Entolomataceae, many reports of and have been published, but few reports on and allied genera are available. In this study, , and from China were studied by morphological and phylogenetic methods. Portions of nuc 28S rDNA (28S), RNA polymerase II second largest subunit (), translation elongation factor 1-alpha (), and ATPase subunit 6 (), were employed to elucidate the relationships of and allies.

Phylogenetic overview of (Boletaceae, Boletales), with descriptions of six new species from China.

In this study, species relationships of the genus were studied, based on both morphological characteristics and a four-gene (nrLSU, , and ) phylogenetic inference. Thirty-five species of the genus have been revealed worldwide, forming eight major clades in the phylogenetic tree, of which twenty-four species have been found in China, including six new species: , , , , , and a new combination (Bi & Loh) Ming Zhang, N.K.

Molecular cloning and the expression pattern of AePOPB involved in the α-amanitin biosynthesis in Amanita exitialis fruiting bodies.

Amanita exitialis Zhu L. Yang & T. H.

Illumina-based de novo transcriptome sequencing and analysis of Amanita exitialis basidiocarps.

Amanita exitialis is a lethal mushroom that was first discovered in Guangdong Province, China. The high content of amanitin in its basidiocarps makes it lethal to humans. To comprehensively characterize the A.

Peptide toxin components of Amanita exitialis basidiocarps.

Eight peptide toxins were isolated and purified from basidiocarps of Amanita exitialis with high performance liquid chromatography and were subjected to ultraviolet, nuclear magnetic resonance and mass spectrometry. We identified seven peptide toxins, α-amanitin, β-amanitin, amaninamide, phallacin, phallacidin, phallisacin and desoxoviroidin. The molecular weight (729.
