Hedgehog Mushroom
Scientific Name: Hydnum repandum
The Hedgehog Mushroom, also known as the Sweet Tooth, is an exceptionally highly prized, choice wild edible mushroom native to temperate forests across Europe, North America, and Asia. Growing in mycorrhizal symbiosis with both deciduous and coniferous trees, it is highly celebrated as one of the safest and most delicious mushrooms for wild foraging. Lacking true gills or pores, its defining, unmistakable characteristic is the presence of hundreds of tiny, delicate, soft, spine-like teeth densely covering the underside of its pale peach-orange cap, producing a rich, sweet, nutty, and slightly peppery culinary experience.
How to Identify
A pale peach-yellow cap with hundreds of tiny, delicate, soft, spine-like teeth underneath instead of gills, growing on soil under mature trees.
- Tiny Soft Spines: The underside of the cap is densely covered in hundreds of tiny, delicate, soft, 2 to 6 mm spine-like teeth (spines).
- Pale Peach-Yellow Cap: A smooth, dry cap, 5 to 15 cm, ranging from pale cream-yellow to beautiful peach-orange with a wavy margin.
- Non-bruising Solid Stem: A thick, solid, off-center white stem that does not stain blue or change color significantly when bruised.

Frequently Asked Questions
Why is it called 'Hedgehog Mushroom'?
It is named the 'Hedgehog Mushroom' because the tiny, soft, downward-pointing teeth covering the underside of its cap strongly resemble the defensive spines of a tiny forest hedgehog.
Are there any toxic look-alikes?
No. The Hedgehog Mushroom has no toxic look-alikes. There are absolutely no poisonous mushrooms in the world that have soft, spiny teeth under the cap, making it one of the safest wild mushrooms to forage.
Do I need to peel off the teeth before cooking?
Do I need to peel off the teeth before cooking?
On young, small button specimens, the teeth are sweet and tender, so you can cook them intact. On older, mature specimens, the teeth can develop a slightly bitter or muddy taste; simply scrape them off with a thumb or knife before cooking.
Does the flesh change color when cut?
No. Slicing the firm, dense white flesh does not trigger any dramatic bruising or color change, though it may turn a very slow, faint, pale yellowish-orange over several hours, which is completely safe.
