Cortinarius species are widely distributed in the world and constitute a diverse group of ectomycorrhizal fungi that are associated with a broad range of plant hosts. The species diversity of this genus has been investigated in China, but it remains poorly understood, especially in the subtropical region. In this study, one new section, six novel species, one new combination, one new name, and one new record of Cortinarius are reported from subtropical China based on the morphological and molecular evidences. Cortinarius lilacinicarpus, C. sinocalaisopus, C. sinosalor, C. vividus spp. nov., C. orientisalor nom. nov., and C. illibatus are typical species of the section Delibuti. Cortinarius macroflavicapus sp. nov. belongs to Macroflavicapi sect. nov., a new section in the subgenus Dermocybe. Cortinarius tianbaoyanensis sp. nov. and C. dryadicola comb. nov. belong to the section Spilomei. Detailed descriptions, basidiocarps, and microscopic photographs are provided for these species. In addition, C. leptospermorum comb. nov. in the section Pauperae and subgenus Dermocybe is proposed.

The major pathologic hallmark of the alcoholic liver disease (ALD) is the representation of chronic alcohol-induced hepatocyte lipid accumulation. This study aims to investigate the hepatoprotective role of triterpenoids-enriched extracts from Antrodia cinnamomea mycelia (ACT) in chronic alcohol-induced liver injury mice, establishing in C57BL/6 mice through gradient alcohol feeding for 24 weeks. In long-term alcohol consumption mice, the significantly lost body weight, increased organ indexes, hepatic alanine aminotransferase and aspartate aminotransferase levels were all remissed after 6-week ACT orally administration, showing its hepatoprotective property. ACT suppressed the triglyceride, total cholesterol and low-density lipoprotein levels, and enhanced high-density lipoprotein levels in serum or/and liver of chronic alcohol damaged mice. Combining with the pathological observations, ACT displayed an anti-steatosis effects to restrain the progress of ALD. Based on proteomic analysis and enzyme-linked immunosorbent assay, ACT had been confirmed to regulate the levels of lipid biogeneration-related factors and depressed the over-accumulation of hepatic reactive oxygen species. According to further data, ACT prevented alcoholic liver injury may be associated with mediating lipid metabolism-related to PGC-1α and NF-κB signaling. In summary, ACT protected the body against chronic alcohol ingest induced liver injury through its regulation lipid on metabolism.
