Trametes is a genus of fungi that is distinguished by a pileate basidiocarp, di- to trimitic hyphal systems, smooth non-dextrinoid spores, and a hymenium usually without true hymenial cystidia. The genus has a widespread distribution and contains about fifty species. The genus was first described by Elias Magnus Fries in 1835. Trametes fungi are food for caterpillars of certain Lepidoptera, mainly fungus moths (Tineidae) such as Triaxomera parasitella.
