The fungus in the photo (left) appeared on rotting, chopped-up trees used as mulch in our garden. It is about 10 centimetres in diameter and appears to feed on insects, and so has an appropriate stink of rotting flesh. What is it?Ted Webber, Buderim, Queensland, Australia
Is it actually feeding on insects, or attracting them for propagation? I would expect the second is more likely. Carnivorous plants typically capture prey as a supplement in nitrogen-poor soils like bogs. I also do not recall a carnivorous fungus which preys on insects; their typical prey is nematode worms.This is probably a flower which uses carrion scent to attract polinators, that being a common reproductive strategy. Many of them do resemble fungi, as they have fleshy petals to augment the illusion. I did a quick search, but was unable to find a match for the appearance.
This is a fairly unusual tropical member of the ornate stinkhorn family (Clathraceae) known the starfish fungus (Aseroe rubra). Like other stinkhorns, this peculiar fungus emerges from a subterranean "egg" stage. At maturity it has five to ten radiating arms, each divided into two slender "tentacles." A slimy, black spore mass occurs in the center and at the bases of the radiating "tentacles." The spore slime has a fetid odor resembling rotten meat. Interestingly, the only other picture of it I have ever seen was taken on the island of Maui.Brian Kiernan
http://fungimap.rbg.vic.gov.au/fsp/sp003.htmlthis would most likely be the case as brian said as it seems to fit the bill. we have a few of these in billinudgel which is near Byron bay and they have a tendency to be somewhat smaller than the 10cm in girth. However things do grow differently in different climates. I did a few searches on the term "dead mans fingers" and found that it most probably is not thathttp://botit.botany.wisc.edu/toms_fungi/apr2000.htmlhowever i could be wrong as i am not a botanist just an enthusiastDanny
