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.

Common Rustgill
Gilled
An abundant orange-tawny wood-rotter of conifer plantations, identified by its smooth dry cap, yellow gills that become freckled with rust spots, and rusty spore print.
Spore print · Rusty brown
Common Jellyspot
Jellies
Minute orange-yellow jelly blobs scattered in numbers over damp dead wood and old fence posts, among the most frequently encountered of all small fungi.
Spore print · Whitish to pale yellow
Ash-tree Bolete
Boletes
An unusual bolete found only near ash trees, with an off-centre stipe and a shallow, vein-like yellow pore surface that radiates outward like gill folds.
Spore print · Olive-brown to yellow-brown
Weeping Bolete
Boletes
A slippery cinnamon-brown bolete of pine woods whose pale yellow pores exude milky droplets in humid weather, giving it its name. The ringless stalk is dusted with fine brown granular dots.
Spore print · Cinnamon-brown
Oyster Rollrim
Gilled
A stalkless ochre to yellow-brown fan on conifer wood, recognised by its inrolled wavy margin and soft, crowded, strongly forked and cross-veined orange-buff gills that separate easily from the flesh.
Spore print · Pale yellowish brown
Girdled Knight
Gilled
A grey willow-associated knight that is unusual in its genus for having a distinct woolly white ring on the stipe. The small fibrillose-scaly cap and faintly yellowing gills complete the picture.
Spore print · White
White-pored Chicken of the Woods
Polypores
Forms a broad rosette of soft salmon-orange fans on the ground at the base of oaks, distinguished from its relatives by a white to cream pore surface rather than a yellow one.
Spore print · White
Small Chanterelle
Gilled
A miniature orange-yellow chanterelle, often no wider than a fingernail, scattered in moss beneath oaks. Its thin flesh, widely spaced blunt ridges and slender stalk are diagnostic.
Spore print · Pale yellow to whitish
Red Cracking Bolete
Boletes
A small woodland bolete whose dull brown cap cracks into a mosaic with pinkish-red flesh showing in the fissures. Yellow pores bruise blue-green and the stipe is red-streaked.
Spore print · Olive-brown
Cortinarius rubellus
Gilled
A slender foxy-orange webcap of mossy conifer forest, recognised by its sharply umbonate fibrillose cap, thick widely spaced rusty gills and pale yellow bands on the stipe.
Spore print · Rusty brown
Scarletina Bolete
Boletes
A stout, dark-capped bolete with blood-red pores and a yellow stipe peppered with fine red dots, whose lemon flesh turns instantly inky blue when cut.
Spore print · Olive-brown
Thick-footed Morel
Morels & Allies
The traditional name for the largest yellow morels, distinguished by a swollen, deeply furrowed and chambered stalk base beneath a broad ochre honeycomb cap. Specimens can exceed 25 cm in height.
Spore print · Cream to pale yellow
Cortinarius orellanus
Gilled
A medium-sized tawny webcap of oak and beech woodland with a dry, finely scaly convex cap, thick distant cinnamon gills and a tapering yellow-brown stipe without veil belts.
Spore print · Rusty brown
Green Skinhead
Gilled
An unusual olive-green webcap with a dry, finely felted cap, green gills that rust with age and greenish-yellow flesh. Green is rare among gilled fungi, making it easy to spot.
Spore print · Rusty brown
Deceiving Milkcap
Gilled
A small, pale pinkish-tan milkcap whose white latex turns bright yellow within seconds of exposure. A faint geranium-like odour and a preference for hornbeam and hazel help confirm it.
Spore print · Pale cream
Chanterelle
Gilled
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
Bay Bolete
Boletes
A rich bay-brown bolete whose lemon-yellow pores flush blue-green within seconds of being touched. The stipe is brown-streaked and lacks the raised netting of the King Bolete.
Spore print · Olive-brown
Blushing Morel
Morels & Allies
A pale, greyish to yellow-brown morel of mulch and disturbed ground whose ridges and stalk stain pinkish, rusty or ochre-brown where handled or with age. It is one of the earliest-branching lineages in the genus.
Spore print · Cream to pale yellow
Birch Milkcap
Gilled
A small tawny orange-brown birch associate with a matt, slightly wrinkled cap and a small pointed umbo. Its scanty white latex slowly turns yellow when smeared on a white tissue.
Spore print · Pale cream
Liver Milkcap
Gilled
A small dark liver-brown milkcap of pine litter on acid soils, whose white latex turns clear yellow when blotted onto a white cloth. It fruits late in the season, often in dense troops among needles and moss.
Spore print · Pale cream with pinkish tinge
King Bolete
Boletes
A heavy, bun-shaped brown bolete with a stout swollen white stipe carrying fine pale netting, and a sponge layer that ages from white through cream to olive-yellow without bruising blue.
Spore print · Olive-brown
Snow False Morel
Morels & Allies
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
Porcini
Boletes
The archetypal stout bolete, with a smooth brown bun-shaped cap, white pores ageing yellow-olive, and a swollen pale stipe netted with fine white reticulation. Flesh stays white and unchanging when cut.
Spore print · Olive-brown
Fiery Milkcap
Gilled
A grey-buff milkcap with faint watery zoning and unusually well-spaced ochre-yellow gills, found almost exclusively under hazel. Its white latex dries greyish and its gill spacing sets it apart from other grey milkcaps.
Spore print · Pale cream to pale yellow
