Boletes are fleshy fungi with a central stalk like agarics (mushrooms toadstools) but the underside has pores instead of gills. Polypores have pores like boletes but are generally tough or leathery fungi that usually arise from wood.
in good years rings of salmon gum bolete form around trees that they are associated with in the arboretum. I call them goblin rings because they are too big for fairies
There are still lots of boletes that remain unnamed, and many boletes change colour ('stain') when bruised or cut.The one below is a blue stainer. Yellow pores and white flesh turn blue when cut or bruised.
First nations people used to eat these fungi.
