Thanks for the identification @Heinol I’ve looked back through my previous sightings and am fairly certain that this Common Prettymouth is the same one recorded in sighting 4680226 on 6th June 2025, almost ten months ago, based on debris embedded in the surrounding embankment. The puffball has grown slightly in size since that first sighting and shows minimal deterioration and physical damage despite its location and the environment it has been subjected to high up at Tidbinbilla Nature Reserve. I had no idea that this type of puffball is so rugged and takes so long to mature.

An interesting observation. I haven't come across reports of the longevity of the fruitbody in this species. At the time of the earlier sighting it would already have been mature. Puffballs and their kin, once mature, can be around for months and shed spores over a long time but usually you can tell when one's been around for a while because there are obvious signs of weathering.
