How to separate similar species

Compare especially with these similar species: Tremella species, Exidia species, other jelly fungi. Check the entire fruitbody, spore-bearing surface, stem, texture, changes after bruising and habitat. A single feature or photograph is not enough for reliable identification.

Similar species

    Tremella species are also gelatinous but lack the densely toothed underside of Pseudohydnum.
