Description

The fruitbodies of ''Antrodiella'' fungi are either crust-like to effused-reflexed (stretched out on the substrate but with edges curled up to form cap-like structures) in form. They have a waxy and soft fresh texture that becomes dense and hard, and often semitranslucent when dry. If it is present, the cap is narrow and light-coloured, smooth to scrupose (rough with very small hard points). The pore surface is light ochraceous to straw-coloured when dry, with small pores, and the tubes the same colour as the pore surface. The
