The two fruit bodies were alongside a driveway and about 5 metres away from a eucalypt. Photo 1 shows the two mature specimens when I collected them (January 12). Photo 2 shows them on January 8 and Photo 3 on January 4. Photo 5 shows the larger specimen, halved vertically so as to reveal the internal structure. At arrow 1 you can see some speckling, but otherwise no structure. Development is more advanced within the white ellipse, where you see what look like blackish-brown rice grains. Within each ‘grain’ there are spore-producing organs (the basidia) and once spores have ben produced the ‘grains’ walls and basidia disappear to leave a mass of powdery spores. At arrow 2 you se no ‘grains’ but lots of powdery spores. The outer skin breaks away to expose the powdery spores and allow their dispersal by wind. As the spores at 2 disappear, the area lower down will mature, the spores there will disperse and so on. Over time more and more of the fruit body would disappear, from the top down.
