Puffballs & the like


At maturity, the fruitbodies of the fungi in this group generally contain prodigious quantities of powdery spores. The fruitbodies may be spherical to pear-shaped or somewhat columnar in shape and range from less than a centimetre to over 30 centimetres in extent. Spores are mostly some shade of brown, from pale yellow-brown to dark brown, depending on species.

 

Almost all species produce their fruitbodies on the ground, a few produce them on on wood.

 

In the following hints you see examples of useful identification features and a few of the more commonly seen genera in which at least some species (not necessarily all) show those features.

 

Hints

Spore mass lilac: Calvatia.

Fruitbody over 30 centimetres in diameter: Calvatia.

 

Warning

If you have a flattish fruitbody, with purplish-black powdery spores inside a thin, brittle crust - check the slime mould Fuligo septica.

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.

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.

Thanks, that describes the inside very well

A species of either Bovista or Lycoperdon. Until the spores start maturing the inside is boringly homogenous.

Probably a species of either Bovista or Lycoperdon.
