Hygrophorus cossus is a waxcap fungus in the family Hygrophoraceae, assessed as Critically Endangered (CR). It grows in old-growth forest habitats, particularly in association with ancient trees, and is named for its distinctive soapy or waxy odour. Its critically endangered status reflects extreme rarity and the near-total loss of suitable old-growth forest habitat.
