"Arrhenia" also includes species formerly placed in the genera "Leptoglossum" and "Phaeotellus" and the lectotype species itself has an unusual growth form (discussed below) that would not normally be called agaricoid. All of the species grow in association with photosynthetic cryptogams such as mosses, including peatmoss, and alga scums on decaying wood, and soil crusts consisting of mixes of such organisms. Typically the fruitbodies of "Arrhenia" species are grey to black or blackish brown, being pigmented by incrusting melanized pigments on the hyphae.Etymology "Arrhenia" was named for the botanist J. P. Arrhenius.
