Binomial name: Antrodiella zonata
Synonyms: Irpex brevis, Irpex consors, Irpex zonatus
Antrodiella zonata is a very common fungus (30mm) found growing in tiers of brackets on rotting native and introduced hardwoods and fallen branches throughout the year.
It has a variable form. Each bracket is usually broadly attached but occasionally they can be spatula shaped and have a narrow attachment point. They can appear whitish or a pinkish brown in colour.
The underside of the fruiting body is covered in imperfectly formed pores which appear as partially tubular teeth (2-3 mm long).
