subsection (Hygrophoraceae, Agaricales) in China.

Hygrophorus subsect. Hygrophorus has been relatively well-studied in Europe and North America, but studies on the taxa in Asia, particularly in China, are still limited. In this study, phylogenetic overviews of genus , based on the nuclear large subunit (LSU) ribosomal RNA gene and of subsect.

Additions to tribe Chromosereae (Basidiomycota, Hygrophoraceae) from China, including gen. nov. and a first report of .

, typified by , is described upon morphological and molecular evidence. The new genus is characterised by its sinuate to subdecurrent or short deccurent, usually furcate and interveined and relatively distant lamellae, dry and whitish tomentose stipe, thin-walled ellipsoid to oviod, non-constricted basidiospores and particularly elongated basidia and a ratio of basidiospore to basidium length of >5 to 8; it is close to genera and of the tribe Chromosereae, but morphologically differs from in less umbilicate basidiomata, tomentose stipe and usually longer basidia and differs from in more robust basidioma and less glutinous pileus and/or stipe surface. Phylogenetic analyses, with ITS-LSU-RPB2 data, also indicate that forms a very distinct and independent clade at the generic level.

[Study on biological characteristics of Cordyceps ramosa mycelia].

Objective: To study the biological characteristics of Cordyceps ramosa mycelia.

Methods: The effects of temperature, pH, carbon source, nitrogen source and C/N ratio on the mycelial growth of Cordyceps ramosa were investigated.

Results: The optimum temperature, pH, carbon source, nitrogen source and C/N ratio for the mycelial growth were 25 degrees C, 5.

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.
