Gilled fungi have a cap with vertical plates underneath radiating from the stem or point of attachment.

Boletes have a central stem, and a cap with pores underneath. The layer of tubes that ends in the pores is readily separable from the flesh above it.

Polypores have pores on the underside of the cap (or sometimes on a surface that is flat against wood). If there is a stem, it is usually at the side of the cap.

Crusts grow flat on wood, mushrooms, or other surfaces, and do not have pores, but may have teeth and may be jelly-like in consistency; includes Hypomyces and parchments like Stereum.

Toothed fungi have teeth on the underside of their caps. For flat toothed fungi, see Crusts.

Veined fungi have folds or ridges on the undersides of their caps, instead of gills. Chanterelles are an example.

Bird's Nests are small species most often growing on wood which have an outer nest-like shell, and when uncovered have lens-like 'eggs' inside.

Club-shaped fungi are unbranched and usually upright and may or may not have a differentiated head.

Coral-like fungi are fleshy fungi that are branched and coral-like. Leafy forms like Thelephora and Sparassis are included here.

Jelly fungi have jelly-like consistency, and are most often yellowish or translucent in color, but may be brown to black. For flat jelly fungi, see Crusts.

Puffballs, earthballs, and earthstars have a outer case with spore mass inside. In earthstars, the outer case splits and peels back.

Truffles and false truffles are those species that grow underground.

Morels, false morels, and elfin-saddles have differentiated heads which are convoluted or saddle-shaped.

Cups are cup-shaped or disc-shaped, and may or may not have a stem.
