During the warmer months, and usually after a bit of rain, you may see a great variety of robust fungi appearing in Tasmania - including mushrooms with pores - often known as 'Boletes'.
Bolete mushrooms have pores instead of gills and are usually found on the ground on soil, where they may form relationships with native trees underground and quite often you will also find types of Boletes on well rotted stumps/logs in the wet forest. Bolete 'Stephen' can grow quite large (over 20cm across), and has a yellow cap and yellow pores, and when the flesh of this mushroom is cut, turns a spectacular blue when exposed to air! It is found from November - April in Tasmania according to A Field Guide to Tasmanian Fungi by Gates & Ratkowsky 2014.
