This is a very nice set of photos of Aseroe rubra, a target species in Fungimap (https://fungimap.org.au/), a community-based project aimed at helping map the distribution of a number of fungal species that are easily recognizable by the naked eye. You don't need and prior fungal knowledge and no collecting of specimens is necessary.

I'm going out on a limb on this one, but I wonder if this is Anthurus archeri. We usually just say that Aseroe rubra has bifid arms, and Anthurus has arms that are not split - but I've seen a few (rare) images now where what otherwise seems to be Anthurus archeri has the arms split at the tips. Also, in Aseroe rubra there is often a disc at the top of the stipe, from which the arms arise, often more or less hoizontally at maturity, whereas in Anthurus archeri the arms just come off the basal tube, and stay fairly vertical (or flopped over) as in this image. In Anthurus archeri the arms are joined at the tips when young, but this connections disappears when old. Anthurus archeri and Aseroe rubra are meant to be nice and simple to identify, which is why they are Fungimap targets! However, stinkhorns can be very variable (as seen in the images on the Atlas of Living Australia at Acacia ausfeldii#tab_gallery).

Thanks Tom. This is interesting, yes looking at the ALA and Google Images for this species demonstrates what you are saying. I've just made a new suggestion for Anthurus archeri over the top of the existing confirmation, but we should now await Heino / Michael's response. Thanks for your advice on this one too. Cheers Aaron.

Quite right Tom. Haven't the faintest idea what I was thinking of in September! Perhaps thinikng one thing and typing another - or else stupidity had already set in. Current thinking actually puts Anthurus archei into Clathrus, in which the structure is cage-like, that is everything united at the top.
