 They range from effused (crust-like), to effused-reflexed (crust-like with edges curling to form rudimentary caps) or cap-like, with a texture ranging from membranous, to leathery or soft corky.The spore-bearing surface are often tooth-like, bumpy with tubercles, or spiny.In some species the surface is poroid, daedaleoid (maze-like), and sometimes develops irregular ridges or hyphal pegs (bundles of hyphae that project from the hymenium).
