Hi Kylie. I think it's the same situation here. These fungi have appeared on chipbark used as a mulch, but so far just in this one location. I've searched the other mulched areas nearby but so far no Craypot Stinkhorns have appeared. Tim
One year on southern NSW coast this was distributed when chipbark was used wide and far on street and park trees as mulch - and these came up everywhere from the chipbark. Until then I''d never seen it (or smelt it).
