Some fungus

On our dog walk this morning Frances spotted an unusual (for this area) fungus.  I had seen them before at Carwoola and knew it to be the Rooting Shank, Oudmansiella gigaspora (although I'd previously seen it identified as O. radicata).

 On returning to photograph it the neighbour on whose block it was growing pointed out where a much larger fungus was to be found.  Indeed much larger - perhaps 20cm across.  It is clearly a bolete but with the size and apparently dark undersurface I can't put a species to it.

On revisiting the fungus I poked it with a stick (not burnt) and it bruised blue.  This may help identify it.
