Michael F, You are almost right . But as you can see in the LINK all these mushrooms are round . Mine are square ??? http://www.messiah.edu/Oakes/fungi_on_wood/gilled fungi/species pages/Armillaria tabescens.htm Pity there is not more interest in Aussie Plants and stuff.
Can't say I would have known they were Oz in origin. Fungus/mushroom I guessed but not the technical names. Do you have more info as to location to educate us on this so that at least those of us in Australia can be more aware. For example is it a Qsld thing or is it found in the cool temp. rainforest areas as well. I am amazed at the amount of Australian plants that are mentioned on here but I suppose fungi is a specialist area. Liz
The square edges are exactly how I found it . Each one is only about 3/4 inch. square . I have included a bigger Pic. to show how many there are . To many to tamper with . Although there are some smaller clumps of round ones on the same log . I am seriously thinking of going back there next week-end and taking some samples home for Studio Shots .
