Australian Austrobolete mushrooms

Three Australian Austrobolete Mushrooms

Austroboletus is a genus of fungi in the family Boletaceae. They have pores rather than gills and used to be classified as a type of Boletus. However, since 1979 they have been classified as a separate genus because their spores are pitted rather than smooth like bolete spores as shown in this photo by Roy Halling (Mushroom Observer) [CC BY-SA 3.0 (http://creativecommons.org/licenses/by-sa/3.0)], via Wikimedia Commons

At the macro level Australian Austroboletes are recognised via their lacunose stems, which are like a lattice.
