Pseudohydnum gelatinosum, also known as Toothed Jelly Fungus, is a unique and intriguing species of fungus that stands out for its jelly-like consistency and distinctive toothed undersurface. Found primarily in temperate forests, this translucent, gelatinous mushroom typically grows on decaying wood, often forming clusters of small, whitish to pale grey fruiting bodies. Its unusual texture and appearance make it a fascinating find for mycologists and mushroom enthusiasts alike.

Fruiting body tongue-shaped or kidney-shaped with a broadly convex or flat appearance, the fungus has a gelatinous texture that is smooth or finely fuzzy to the touch, but not slimy. It ranges in colour from translucent white to greyish, brown, or a fairly dark brown, with a margin that is tucked under when young. The undersurface features spines up to 3 mm long that run down the stem, and is typically translucent white or pale greyish in colour. Spore print white.

Microscopic Features: The spores are spherical or nearly so, smooth in texture, and measure 5-6 x 5-5.5 µm. They are inamyloid, meaning they do not stain blue or black when exposed to iodine.
