Description

The Jelly Tooth is a unique mushroom combining features of toothed fungi and jelly fungi. Cap 2-8 cm across, spatula or fan-shaped, translucent gray-white to pale brown with a gelatinous texture. The upper surface is smooth and jelly-like. The underside bears soft white spines/teeth (0.5-3 mm long) instead of gills or pores. The stem is lateral (off-center) or absent, 1-4 cm when present. Texture is rubbery-gelatinous, firm but translucent, reviving when moistened after drying.

Phlebia tremellosa (inedible)

HOW TO TELL APART

jelly-like but lacks teeth, has wrinkles/folds

Hericium species (edible)

HOW TO TELL APART

white teeth but firm flesh, not gelatinous

Tremella species (edible)

HOW TO TELL APART

brain-like, no teeth

No toxic lookalikes
