Polypore fungi forming bracket to crust-like basidiocarps, causing a white rot of dead wood.

Five or six species have been reported from New Zealand, almost all apparently restricted to the North Island. One exception is a species referred to by G.H. Cunningham as Poria undata (an incorrectly applied Northern Hemisphere name); this has a curious distribuition with two centres, one around Northland, the other around Southland, suggesting that there may be two distinct species grouped under this name.

While A. zonata has fine teeth or warts on its spore-bearing surface, other species of Antrodiella in New Zealand have pores, not teeth.
