The Coral Tooth Mushroom (Hericium coralloides) is a beautiful, edible fungus known for its intricate, white, coral-like branches with dangling spines, growing on dead hardwoods, offering a mild, sweet, sometimes peppery taste, and containing beneficial compounds similar to Lion's Mane, but it can turn yellow and brittle with age, requiring careful identification and consumption when young and firm. 
Key Things to Know:
Appearance: Striking, white, branching structure resembling marine coral, with short spines (less than 1cm) hanging down; turns yellowish with age.
Habitat: Grows on dead or decaying hardwood trees (saprophytic) in forests.
Edibility: Choice edible when young and fresh (firm, white, bouncy), but should be avoided if yellow, brittle, or slimy.
Taste & Texture: Mild, slightly sweet, sometimes peppery; has a crunchy texture when cooked.
Identification: Part of the Hericium genus, related to Lion's Mane, but more delicate and branched with shorter spines.
Health: Contains compounds like hericenones, erinacines, and unique corallocins, studied for potential neurological benefits, similar to Lion's Mane.
Preparation: Sauté with butter/oil, use in soups, or stir-fries; cook lightly to retain texture. 
Important Considerations:
Age is Key: Only eat fresh, white, firm specimens; discard any that are yellowing, dry, or mushy.
Never Eat Raw: Even if it tastes mild raw, always cook mushrooms.
Overindulgence: Some people experience digestive upset if they eat too much. 
Coral tooth mushrooms (Hericium coralloides), a close relative of the more famous lion's mane mushroom, offer several potential health benefits, primarily related to brain health, antioxidant effects, and immune system support. 
Potential Health Benefits
Neuroprotective Effects: Coral tooth mushrooms contain bioactive compounds like hericenones and erinacines, which are believed to stimulate Nerve Growth Factor (NGF) synthesis. Ongoing research suggests they may offer neuroprotective benefits and help ameliorate symptoms of cognitive decline and Alzheimer's disease by reducing amyloid-beta plaques and p-tau deposition in the brain.
Antioxidant and Anti-inflammatory Properties: The mushroom exhibits strong antioxidant activity, which helps reduce oxidative stress and cellular damage in the body. It contains polyphenols and other phenolic compounds that can help manage systemic inflammation.
Immune System Support: Like many medicinal mushrooms, coral tooth is believed to have immunomodulatory properties, meaning it may help support and regulate the immune system by activating certain immune cells.
Gut Health: The mushroom contains dietary fiber which supports digestive health and regularity. There is ongoing research into the potential of Hericium-derived polysaccharides acting as prebiotics to benefit gut microbiota, and animal studies have shown it can regulate gut bacteria composition.
Nutritional Value: Coral tooth mushrooms are low in fat and calories while providing essential vitamins and minerals, including B vitamins (B2, B3, B5), potassium, phosphorus, zinc, and iron. When exposed to sunlight or UV light, they can also become a good source of Vitamin D. 
Traditional Use and Modern Research
Historically, coral tooth fungus was used in folk medicine as a general tonic for digestive disorders and fatigue. While human studies are still limited and more research is needed, current laboratory and animal studies provide promising evidence for its use as a therapeutic agent, particularly in the context of neurodegenerative conditions.
