How to separate similar species

Compare especially with these similar species: Hygrophorus hypothejus. Check the combination of cap shape and colour, spore-bearing surface, stem, flesh changes and habitat. A single feature or photograph is not enough; if the key characters do not match the description, do not treat the identification as confirmed.

Similar species

  • Herald of winter (Hygrophorus hypothejus)

    Late waxcap is usually more yellowish and its lower stem is less distinctly dark-patterned.

  • Hygrophorus dichrous

    Hygrophorus dichrous is usually stouter and characteristically grows with hornbeam rather than spruce.
