Types of fungal fruiting bodies (or sporocarps)

Stinkhorns, puffballs & birds nest fungi

Stinkhorns come in various shapes but all contain a khaki to brownish slime. The unforgettable feature common to all stinkhorns is that they smell of faeces or rotting meat when they first appear. A couple of examples are Anthurus archerii and Dictyophora multicolor .

Puffballs and and the like. The feature common to all of these is that, at maturity, the bulk of the fruiting body consists of powdery spores. Mature puffballs are simply bags of spores, with the bag being somewhat elastic. At the top of the bag is a small opening. Puffballs are no more than a few centimetres in diameter. Bovista is a common puffball genus.

Geastrum sp.

Related to puffballs are the earthstars which look like puffballs on star-like bases. In all earthstars the spore bags are no more than a few centimetres in diameter, with the majority of species having diameters under 2 centimetres. Virtually all earthstars are in the genus Geastrum.

Calostoma fuscum has a globe of spores on top of a braided, rubbery stem.

In other genera, such as Calvatia , Scleroderma and Pisolithus, the outer skin of the fruiting body is tough or brittle, rather than elastic as in a puffball such as Bovista. As you can see from the photo, the skin of Scleroderma is exceptionally thick.

Cyathus novae-zealandiae

Birds-nest fungi are small, steep-sided cups (up to a centimetre across and of similar height) which contain small disk-like objects, giving the appearance of eggs in a nest. The cups are generally creamy to grey to light brown and are distinct from the cup-fungi mentioned above. Cyathus stercoreus is common on dung and organically rich soils while Cyathus novae-zealandiae grows on well-rotted wood debris.

Cannonball fungi – whereas the fruiting bodies of Birds Nest Fungi are steep sided cups, the cup of the Cannonball Fungus (Sphaerobolus stellatus) is shallow and only about 2mm across. Each cup contains only one 'egg' or 'cannonball'. When immature the whole fruiting body is a closed sphere. In this photograph you can see a line of immature fruiting bodies, going right (and slightly upward) from the centre of the photo.
