Fungal Species: Hericium alpestre

A multilocus phylogeny of Hericium (Hericiaceae, Russulales)

mycolabadmin

Researchers conducted the first comprehensive genetic study of lion’s mane mushrooms (Hericium species) using advanced DNA sequencing techniques. The study resolved long-standing confusion about different species and their relationships, while also describing a new species from western North America. These mushrooms are prized both as food and for traditional medicinal uses, particularly in Asia, and contain compounds with potential anti-inflammatory, antimicrobial, and neuroprotective properties. Better identification of species will help both commercial cultivators and medical researchers work with the correct organisms.

Genome Sequencing of Hericium coralloides by a Combination of PacBio RS II and Next-Generation Sequencing Platforms

mycolabadmin

Scientists successfully sequenced the complete genome of Hericium coralloides, a medicinal mushroom used in traditional Chinese medicine for treating heart disease, cancer, and stomach problems. Using advanced sequencing technology combining long-read and short-read methods, they assembled the 55 million base pair genome containing over 11,700 genes. This genetic blueprint reveals the mushroom contains genes for producing beneficial enzymes and compounds with therapeutic potential. This milestone opens the door for future research to develop new medicines based on this mushroom’s natural bioactive properties.

Polysorbate 80 Differentially Impacts Erinacine Production Profiles in Submerged Cultures of Hericium

mycolabadmin

Lion’s mane mushroom and related Hericium species produce beneficial compounds called erinacines that may protect the brain and help with neurological conditions. This study tested how adding glucose and a substance called polysorbate 80 to mushroom cultures affects erinacine production. Interestingly, while polysorbate 80 helped mushrooms grow more, it reduced erinacine levels in most strains, though effects varied by species. The findings could help cultivators choose conditions to grow mushrooms enriched with specific beneficial compounds.

Whole Genome Sequence of an Edible Mushroom Stropharia rugosoannulata (Daqiugaigu)

mycolabadmin

Scientists have decoded the complete genetic blueprint of the wine cap mushroom (Stropharia rugosoannulata), a popular edible mushroom grown worldwide. The research identified over 12,000 genes and discovered the mushroom contains powerful enzymes that break down plant material, explaining why it grows so well on straw and corn stalks. The study also revealed that different parts of the mushroom (cap and stem) have different functions, with stems focusing on energy production and caps on growth and development.
