Fungi encyclopedia
A reference for the fungi you actually find
Each entry describes one species the way you meet it in the field — the cap and its surface, what sits underneath, the stipe and its base, the spore print colour, the substrate it fruits from, and the species most often confused with it.
Caps with radiating blades beneath
American Caesar's Mushroom
Gilled
A brilliant red-to-orange Amanita of eastern North American oak and pine woods, with yellow gills, a yellow-orange skirt ring and a thick white sac at the base.
Spore print · White
American Matsutake
Gilled
A heavy white mushroom with cinnamon-stained cap fibrils, notched white gills and a thick sheathing ring, pushing up through sandy conifer duff. Its powerful spicy aroma is unmistakable in the field.
Spore print · White
Amethyst Deceiver
Gilled
A small woodland mushroom that is intensely violet when fresh and moist, with thick, widely spaced gills of the same colour and a fibrous, twisted stem. It fades so dramatically as it dries that it can look like a completely different species.
Spore print · White
Aniseed Funnel
Gilled
An unmistakable woodland funnel with a soft blue-green cap and a powerful aniseed scent, growing scattered through autumn leaf litter under broadleaf trees.
Spore print · Pale cream to very pale pink
Banded Mottlegill
Gilled
A widespread mottlegill of compost heaps and manured ground, recognised by a hygrophanous reddish-brown cap that dries with a darker band around the margin and a jet-black spore print.
Spore print · Black
Bare-toothed Brittlegill
Gilled
A firm, muted pinkish-brown brittlegill whose cap skin shrinks back from the rim to expose a fine pale line of gill ends. It partners with oak and beech on well-drained soils.
Spore print · White to very pale cream
Bearded Fieldcap
Gilled
A firm, pale cream fieldcap of grassy places whose cap often cracks in dry weather and hangs shreds of white veil from the margin, giving it a bearded look.
Spore print · Dull brown to snuff brown

Gilled
A small pale milkcap of sandy birch ground, recognised by its almost unzoned whitish-pink cap, finely downy inrolled margin and unchanging white latex.
Spore print · Cream

Blackening Waxcap
Gilled
A sharply conical orange to scarlet waxcap that turns inky black wherever it is bruised or as it ages, ending as a wholly charred-looking fruit body.
Spore print · White
Bloody Brittlegill
Gilled
A firm pine-wood brittlegill with a matt blood-red cap and a stipe usually flushed the same colour. Its slightly decurrent cream gills and dry cap skin set it apart from other red species.

Bloody Milkcap
Gilled
A pine-associated milkcap of southern limestone woodland whose flesh releases dark blood-red latex the instant it is cut, with no orange phase at all.
Spore print · Pale cream to buff

Gilled
A small dark blue-black grassland pinkgill whose pale gills carry a finely serrated blue-black edge visible with a hand lens.
Spore print · Pink
Blue Pinkgill
Gilled
A small but unmistakable New Zealand mushroom with an intensely blue, conical, pointed cap and pinkish gills that yield a pink spore print. It grows singly or in small groups in wet native forest litter.
Spore print · Pink
Blue Spot Knight
Gilled
A silky, pure white woodland knight whose cap and stipe base develop distinctive blue-green or pinkish spots and streaks with age. The white sinuate gills and complete absence of a volva place it firmly in Tricholoma.
Spore print · White
Blushing Milkcap
Gilled
A very large, heavy white milkcap blotched with wine-red or vinaceous patches, distinguished by crowded pink gills and copious white latex. It grows exclusively with poplars and willows, often in dune slacks and damp sandy ground.
Spore print · Pale pinkish-cream
Brick Cap
Gilled
A clustering wood-rotting fungus with a brick-red cap fading to buff at the rim, pale gills that age to greyish purple-brown, and a rusty-based stem with only a faint fibrous ring zone.
Spore print · Purple-brown

Gilled
One of the commonest small brown mushrooms of mown lawns, with a two-tone drying cap and mottled dark brown gills that give a dark brown rather than black spore print.
Spore print · Dark brown
Brown Roll-rim
Gilled
A dull ochre-brown mushroom with a persistently inrolled, felty cap margin and decurrent gills that bruise dark brown and peel away from the cap flesh.
Spore print · Yellow-brown to sienna
Butter Waxcap
Gilled
A small buttery-yellow waxcap with a slightly greasy cap, a dry stem and pale yellow gills that run a little way down the stipe.
Spore print · White
Button Mushroom
Gilled
A stocky white or tan Agaricus with free gills that run from pale pink through cocoa to blackish brown, a simple membranous ring, and no volva at the stem base.
Spore print · Dark chocolate brown
Caesar's Mushroom
Gilled
A striking Mediterranean Amanita with a smooth orange cap, a strongly grooved margin, deep golden-yellow free gills and stem, and a thick white membranous sac at the base.
Spore print · White to pale cream
Candy Cap
Gilled
A rusty orange-brown milkcap of the Pacific coast with a dry, faintly wrinkled cap and thin watery latex. Dried fruitbodies develop a powerful sweet aroma often likened to maple syrup or fenugreek.

Cedarwood Waxcap
Gilled
A small pure-white grassland waxcap with broadly decurrent gills and a distinctive scent of cedar pencil shavings.
Spore print · White
Chanterelle

A solid egg-yellow funnel-shaped fungus whose underside carries blunt, forking, decurrent ridges rather than true gills. The flesh is white and fibrous and the odour is faintly of apricots.
Spore print · Pale cream to yellowish
Charcoal Burner
Gilled
A common woodland brittlegill with a variably purple, green and slate-grey cap, unique in the genus for gills that are soft, greasy and flexible rather than brittle and shattering.
Spore print · White
Cleft-foot Amanita
Gilled
An eastern North American amanita recognised by its dark brown, patch-flecked cap and by the abrupt basal bulb that splits into vertical clefts. Cut or bruised tissue slowly darkens to reddish brown.
