If you search the floor of a woodland hard enough, you can find a fungal palette to rival any springtime floral display, particularly in autumn. We’ve chosen a range of fungi to reflect form as well as colour, from the prince – a majestic woodland mushroom – to the tiny pinwheel shapes of the delicate collared parachute.


No two woods are the same, so the fungi you discover may reflect subtle differences in soil type, drainage and prevailing weather.

What are mushrooms?

Mushrooms or toadstools – call them what you will – are the colourful manifestations of subterranean fungal webs or mycelia, which comprise the real engine room of our woods.

Some fungi are saprotrophic: they obtain their nutrients by breaking down organic remains. Others form mycorrhizal associations with trees or other plants, in which both partners share nutrients: the mycelia bond with the root cells and thus ferry nutrients to the hosts. Up to 90% of all plants are thought to have such fungal ‘helpers’.

One of the most unusual-looking groups of fungi is the earthstars, which have a spore sac, sometimes raised on a stalk, and surrounded by rays. There are more than 15 found in the UK, and our earthstar identification guide by naturalist Phil Gates describes seven to look out for.

Putting a name to the trees in a wood will tell you what fungi to expect. For example, the magpie fungus occurs mainly in beechwoods, for example, while the sickener prefers pines and the larch bolete is (you’ve guessed it) a denizen of larch plantations.

How to identify mushrooms

  • Join a fungi foray – it’s the best way to pick up ID tips. Many local conservation organisations organise forays on their reserves.
  • Take spore prints from your fungi. Place the cap on a piece of clean paper, cover it overnight and next morning you should have a perfect spore print. Fungi fun!
  • Specialise in a few fungal types, such as colourful waxcaps, coral fungi or boletes. Report unusual finds to your local records group; find a list here.

Correctly identifying fungi to species level is extremely difficult and many species are poisonous, and even fatal, so if you wish to forage fungi, we would advise doing so with an expert.

How to identify woodland fungi

Chanterelle mushroom (Cantharellus cibarius)

Chanterelle mushroom

Chanterelle mushrooms can be found in coniferous and deciduous woods. Brilliant yellow; gills run part of way down thick stem. Edible (delicious).

Chanterelles are common and widespread in the UK.

False chanterelle (Hygrophoropsis aureantiaca)

False chanterelle. Felicity Rose Cole

Cap: 3–8cm. Usually on acid soils in damp conifer woods or heaths. Unlike true chanterelles, barely edible.

Horn of plenty mushroom (Craterellus cornucopioides)

Horn of plenty mushroom

The horn of plenty mushroom is a woodland mushroom that favours deciduous woods and is often found in groups. Blackish, funnel-shaped or tubular cap with frilly edges.

They're quite localised, but horn of plenty mushrooms are easy to see in some spots.

The sickener mushroom (Russela emetic)

The sickener mushroom

Sickener mushrooms occur in pine woods. A ‘brittlegill’ with a scarlet cap and pure white gills and stem; gills break easily when touched. Poisonous.

Sickener mushrooms are common and widespread.

Charcoal burner mushroom (Russell cyanoxantha)

Charcoal burner mushroom

You can find charcoal burner mushrooms in deciduous woods. A ‘brittlegill’ with a lilac or red wine-coloured cap, often with olive tints.

Common and widespread in the UK, it shouldn't be hard to find a charcoal burner mushroom.

Wood blewit mushroom (Lepista nuda)

Wood blewit mushroom

Cap: 6-14cm. Wood blewit mushrooms are found in deciduous woods and hedges. Rich tan cap; lilac stem and gills. Has a sweet, perfumed smell. With age, the bluish-hued cap turns ochre, with wavy edges.

Like many other mushrooms here, wood blewit mushrooms are common and widespread in Britain.

Larch bolete mushroom (Suillus grevillei)

Larch bolete mushroom

As you might guess from then name, larch bolete mushrooms are found under larches. Cap sticky, orange when young, yellower as it matures. Has pores instead of gills.

Larch boletes are localised but easy to see in the right spots.

Common stinkhorn mushroom (Phallus impudicus )

Common stinkhorn mushroom

Common stinkhorn mushrooms aren't particularly choosy and can be found in all kinds of woods. Cap covered in slime when fresh; releases foul smell to attract flies that spread its spores.

Given their non-choosy nature, it's not surprising that common stinkhorns are common and widespread.

Hedgehog mushroom (Hydnum repandum)

Hedgehog mushroom

Hedgehog mushrooms can be found in most woodland types. Cap creamy on upperside; underside has soft, pale spines (hence the name).

Hedgehog mushrooms are common and widespread.

Violet webcap mushroom (Cortinarius violaceus)

Violet webcap mushroom

You'll mainly find violet webcap mushrooms in birch woods. Big, beautiful mushroom with a rich violet cap; browns with age.

Violet webcap mushrooms are scarce and will generally require some thorough searching.

Verdigris roundhead mushroom (Stropharia aeruginosa)

Verdigris roundhead mushroom

Verdigris roundhead mushrooms occur in all types of woodland and also on heaths. Unique turquoise colour with white, fleecy patches when young. Poisonous.

Common and widespread, verdigris roundhead mushrooms shouldn't be too tricky to find but are well worth searching out for their unique colour.

Magpie fungus (Coprinus picaceus)

Magpie fungus

Height: up to 12cm. You'll find magpie fungus in deciduous woods, mainly beech or, occasionally, oak. Bell-shaped cap with irregular white patches, which blackens and liquefies to ‘ink’ as it ages.

Magpie fungus doesn't exist everywhere in the UK, but it's easy to see in some spots in its localised distribution.

Yellow stagshorn fungus (Calocera viscosa)

Yellow stagshorn fungus

Height 2-10cm. Yellow stagshorn fungus can be found in coniferous woods, in small clumps on rotten logs and stumps. Slimy when wet; when dry a deeper shade of orange.

Yellow stagshorn fungus is common and widespread.

Coral spot fungus (Cectria cinnabarina)

Coral spot fungus. Felicity Rose Cole

Bright orange or pink polka-dot pustules. Widespread everywhere on smaller branches and twigs.

Many-zoned polypore (Trametes versicolor)

Many zoned polypore. Felicity Rose Cole

Banded brackets with pale edges; fresh brackets often purplish ‘bloom’. Common on rotting logs.

The goblet (Pseudoclitocybe cyathiformis)

The goblet. Felicity Rose Cole

Cap: 5–8cm. Deciduous woodland, among leaf litter or on well-rotted logs; often persists well into winter.

Plums and custard (Tricholomopsis rutilans)

Plums and custard.Felicity Rose Cole

Cap: 4–12cm. On conifer stumps, especially pine. In spite of its name, bitter-tasting and not edible.

Lilac bonnet (Mycena pura)

Lilac bonnet. Felicity Rose Cole

Cap: 3–5cm. Often under beeches, but also in mixed woodland. Smells strongly of radishes.

Purple jelly disc (Asocoryne sarcoides)

Purple jellydisc. Felicity Rose Cole

Cluster width: up to 10cm. Often on rotting logs of beech and other trees. Brain-like clusters glisten when wet.

Collared parachute (Marasmius rotula)

Collared parachute. Felicity Rose Cole

Cap: about 1cm. On dead roots, twigs and branches of deciduous trees. Gills resemble wheel spokes.

Clouded funnel (Citocybe nebularis)

Clouded funnel. Felicity Rose Cole

Cap: up to 20cm. In deciduous and coniferous woods, forming large fairy rings. Smells fruit-like, but poisonous.

Sulphur tuft(Hypholoma fasciculare)

Sulphur tuft. Felicity Rose Cole

Cap: 4–8cm. Abundant in all types of woodland, on decaying stumps in big golden groups. Blackens with age.

The prince (Agaricus agustus)

The Prince. Felicity Rose Cole

Cap: up to 20cm. In open woodland, under conifers or deciduous trees. Delicious – highly prized. Scare: searching needed

King Alfred’s cakes (Daldinia concentrica)

King alfred's cakes. Felicity Rose Cole

Blackish fruiting bodies; when sliced reveals concentric rings. On tree trunks, especially ash and beech.

Sessile earthstar (Geastrum fimbriatum)

The sessile earthstar has a dimeter of only two centimetres, and becomes grey with age. It has between five and nine rays, which are cream in colour. It occurs across the UK, but is more common in England than the other countries.

It can be found on undisturbed woodland floor, often near hazel. The fruiting body comprises an acorn-like spore sac and curling rays. Usually seen between August and November.
