fruiting bodies are up to 20cm wide, shelf-like, rubbery, sulphur yellow to orange, sometimes with bright orange tips.
older specimens become pale and brittle, chalk-like.
flesh is white to yellow tinted, firm, softer towards the edges.

tip: harvest the soft outer margin of the younger specimens to avoid bitterness.
an inedible (but not poisonous) look-alike is Pycnoporus cinnabarinus, which is corky/rigid rather than rubbery, and orange/red on the top and underside, rather than bright yellow on the underside.
an inedible (but not poisonous) look-alike is Hapalopilus nidulans, which is cinnamon brown/orange on the top and the underside, rather than bright yellow on the underside.
warning: can cause allergic reaction in some people due to toxins absorbed from the tree; begin by sampling small amounts.
