This 'stinkhorn' was the first fungus to be described from Australia. It was recorded on 1 May 1792 from Recherche Bay in Tasmania, just south of Hobart by Labillardiere. The olive-brown slime is the spore mass that is eaten by flys and other insectes which disperse the spores. There appears to be a fair amount of variation within this species. Rangeing from rather delicate forms to the more robust ones like the example you have uploaded. They are saprotrophic (decomposers) and often found in wood mulch.
