Puffballs & the like

Add a sighting Subscribe View significant View unverified

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.

Puffballs & the like

Simple spore sac, with an apical hole [puffballs]

Spore sac on a star-like base [earthstars]

Fruitbody thick walled, splitting from the top

Fruitbody walls break away to expose the spores

This is the sterile base - all that is left after the skin on the upper part has broken up and disappeared, along with all the powdery spores that were there initially.

Thanks very much Teresa, I hadn’t realised the second photo hadn’t loaded.

Scleroderma sp.

This appears to be growing in earth but we need to see more detail of the stem or fine thread connecting it; perhaps you could dig it up and get a few more images to add in identification

Bit of a guess, Lycoperdon sp - can't see enough of the base

Perhaps akin to Bovista plumbea.
