Great to see so many of these fungi turning up in your region. They belong to the same group of fungi as the 'bolete' fungi though this genus has gills rather than pores. They are mycorrhizal, that is associated with the roots of nearby plants with both organisms benefiting. It is interesting to note, if you can, to see if this species has white or yellow mycelium at the base of it's stem. There are many unnamed species in this genus in Australia and unfortunately many have been incorrectly labelled with names of overseas species.
Thanks Pam. I'm planning to head back into the reserve for some more walks this week. I'll take a real camera with me and try to get better detail. There were some more very beautiful but tiny fungi species ... I thought it would be worth capturing them while the conditions are so good!
