The '''Xenasmataceae''' are a family of crust fungi in the order Polyporales. The family was circumscribed in 1966 by German mycologist Franz Oberwinkler with ''Xenasma'' as the type genus.<ref name="Oberwinkler 1966"/> {{As of|2018|April}}, Index Fungorum accepts 28 species in the family.<ref name="CoL-Fungorum"/> Xenasmataceae fungi grow as saprobes on fallen wood and are known primarily from temperate areas.<ref name="Cannon 2007"/>
==Description== Fruit bodies of Xenasmataceae fungi are usually crust-like, with a waxy or gelatinous texture. The fungi have a monomitic hyphal system, and the hyphae are frequently gelatinous. Spores are translucent, and often stain with Melzer's reagent.<ref name="Cannon 2007"/>
