    Here's a stinkhorn from southern Australia about an hour outside of Melbourne in Woori Yallock. It’s definitely from the Phallaceae family and most likely in the Pseudocolus genus. It was about four inches tall with six arms that were only attached to one another at the base and apparently odorless even with obvious gleba. Thanks for the help!

    Agree with Pseudocolus, and I'll guess Pseudocolus fusiformis but that's only because the other species in the genus, Pseudocolus garciae was only known from Brazil as of 1902 (note the story on the spread of Pseudocolus fusiformis in North America from the link above)

    Of all the Phallaceae I've seen it definitely looks the closest but P. fusiformis is reported as only having 3-4 arms and they join at the top. Those differences are too big for this to be a subspecies.

    I would have guessed Clathrus columnatus, the octopus stinkhorn, which often has 5 arms.

    again, this one has six arms that taper off and don't fuse at the top. Definitely not Clathrus columnatus.

    Thanks for the input! I should really be tracking this down in a Australian mycology forum, but there is not the same sort of community here, unfortunately (or at least I haven't found it).

    Cheers,

    Last suggestion --- Clathrus archeri. It has up to 7 arms, and no fusing at the top.

    that's definitely the closest I've seen yet. If nothing else comes to light that's what I'll call it. It doesn't match perfectly in that the one I found never smelled, nor opened, nor were the arms ever fused at the tips. I watched it go from an egg to fully erect (overnight), then over the next ca. 5 days it just wilted and decayed.

    Thanks for looking Rob, much appreciated :)
