Arrhenia is a genus of fungi in the family Hygrophoraceae. Arrhenia also includes species formerly placed in the genera Leptoglossum and Phaeotellus and the lectotype species itself has an unusual growth form that would not normally be called agaricoid. All of the species grow in association with photosynthetic organisms such as mosses and the alga found on decaying wood and soil biocrusts. Typically the fruitbodies of Arrhenia species are grey to black or blackish brown, due to high concentrations of fungal melanin.
Taxonomy Arrhenia was named for the Swedish botanist Johan Peter Arrhenius.
