I found a big and unusual fungus today in the arboretum that looks like a gilled toadstool but is classified as a bolete. A few clues to the classification are:
- It is quite large (20cm diameter here)
- It is very chunky with the fleshy part of the pileus (cap) very thick compared to the gills below
- The gills peel off the fleshy part fairly easily
- A blue stain appears when it is cut (common with boletes) then fades.
Boletes occur regularly in the arboretum, particularly the huge Salmon Gum Bolete, and Slippery Jack.
Images below compare it with a similar looking agaric Austropaxillus infundibuliformis that is commonly found in rock sheoak areas.
It is amazing how quickly fungus fly maggots have eaten out the centre of boletes that look untouched on the outside.
