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.
Shield Dapperling
Gilled
A slender woodland dapperling with an ochre-brown scaly cap, a shaggy fringed margin, and a stem sheathed below the vague ring in loose woolly cotton like a rolled-down sock.
Spore print · White
Shiitake
Gilled
A tough-fleshed wood-rotting agaric with a dry brown cap that cracks into a pale crazed pattern, white notched gills and a fibrous, off-centre stem with a fleeting ring zone.
Spore print · White
Shingled Hedgehog
Toothed
A large brown toothed fungus whose cap is covered with coarse, dark, upturned scales arranged like roof shingles. It grows on the ground under conifers and drops a brown spore print.
Spore print · Brown
Short-stemmed Russula
Gilled
A large, chalk-white North American brittlegill with a deeply funnelled cap, crowded decurrent gills and a very short stout stipe, often pushing up in mounds through forest duff.
Spore print · White to pale cream
Short-stemmed Slippery Jack

Sickener
Gilled
A vivid scarlet brittlegill of wet conifer woodland and bog moss, with pure white brittle gills, a white chalk-like stipe and a cap skin that peels away almost to the centre.
Spore print · White
Silky Parchment

Gilled
A white Pacific Northwest amanita with soft cottony veil patches, a fragile ragged ring, and a tapering, spindle-shaped rooting stem base rather than a sac.
Spore print · White
Smoky Bracket
Polypores
A thin, flexible shelf fungus recognised by the sharp contrast between its pale buff cap, white flesh and strikingly smoke-grey to blackish pore surface that darkens further where handled.
Spore print · White
Smoky Spindles
Corals & Clubs
A grassland club fungus forming dense tufts of slim, unbranched, smoke-grey to pale pinkish-grey spindles that are hollow and very brittle. It is one of the classic indicator fungi of ancient, low-fertility turf.

A large ringless Amanita whose bronze-brown cap carries ragged grey veil patches and whose stem is wrapped in snakeskin-like grey bands above a crumbling volva.
Spore print · White
Snow False Morel

A squat, heavy false morel with a tan to yellow-brown head of rounded brain-like folds and a short, thick, deeply chambered white stalk. It fruits beside melting snowbanks in western mountain conifer forest.
Spore print · White to pale yellowish
Snow Fungus
Jellies
A near-transparent white jelly fungus forming a rosette of thin, frilly, seaweed-like lobes on dead broadleaf branches, drying to a hard yellowish crust and reviving with rain.
Spore print · White
Snowy Inkcap
Gilled
A small, brilliantly white inkcap coated in a floury veil, growing on cow and horse dung in pasture. Its pure white cap darkens and dissolves to black within a day.
Spore print · Black
Snowy Waxcap
Gilled
A small, slender, entirely white waxcap with thick decurrent gills and a tapering stem, often the last waxcap still fruiting in the turf after the first frosts.
Spore print · White
Soapy Knight
Gilled
A highly variable woodland knight with a greenish-grey cap, widely spaced notched gills and flesh that flushes pinkish where cut, especially in the stipe base.
Spore print · White
Sooty Milkcap
Gilled
A dry, matt, sooty grey-brown milkcap of broadleaved woodland whose white latex turns the pale flesh and gills salmon-pink within moments of cutting. That colour reaction is its defining field character.
Spore print · Pale ochre with pinkish tinge
Southern Bracket
Polypores
A heavy, perennial bracket with a thick, hard, dull brown crust and a white pore surface that bruises brown at a touch. Clouds of cocoa-brown spores often dust the bracket and everything below it in late summer.
Spore print · Cocoa brown
Spectacular Rustgill

An extremely common white to cream resupinate polypore whose pores split and fray, becoming maze-like and finally tooth-like towards the centre.
Spore print · White
Spotted Toughshank
