Come and be part of a global voice for wild plants and fungi
This autumn, help us find Britain’s most colourful and important fungi – waxcaps.
Fungi are crucial to nearly all life on Earth, but they are not given the recognition and investment they deserve. Will you join our mission to change that?
Our corporate partners benefit from 35 years of experience in nature restoration so they can achieve real impact.

Amanita muscaria
Fly Agaric can be found in woodlands and along woodland edges. They often reoccur in the same place over multiple years and are widespread throughout Britain and Ireland.
The name Fly Agaric refers to the fungus having been used as an insecticide.
If the white spots wash off the Fly agaric cap, it can be mistaken for red Russula species such as the Beechwood sickener Russula nobilis. There are also other Amanita species which look similar to the Fly Agaric but lack the distinctive red cap (e.g. The Blusher, Amanita rubescens)
Fungi underpin the health of our environment and are key to resolving the climate, ecological and societal challenges we face. Your donation could help increase understanding of fungi and get them the support they need.
Armillaria species
The term Honey fungus actually refers to several closely related species, all within the Armillaria group. The two most common Honey fungus species are Armillaria mellea and Armillaria gallica, however there are a total of seven Honey fungus species found in the UK. These fungi are often well known by gardeners, as they can cause severe disease in trees and shrubs.
As well as producing fruit bodies, Honey fungus forms distinctive bootlace-like structures called “rhizomorphs”. The tough leathery rhizomorphs are formed of bunches of fungal hyphae (root-like threads), and can commonly be seen underneath the bark of trees which have been infected with Honey fungus. Rhizomorphs vary from pale yellow and red, becoming brown or even black as they age.
Honey fungus grows in dense clusters on dead or dying wood, and can be found in woodlands, gardens, and parks.
The different species of Honey fungus can be easily confused with each other.
Armillaria mellea are bioluminescent, their gills glow in the dark! The glow from Honey fungus is very weak however, and is usually too faint to be seen by the naked eye in a woodland environment.
This autumn, help Plantlife find Britain’s most colourful and important fungi – waxcaps.
Laccaria amethystina
Often occurring in large, crowded groups and usually found growing amongst leaf litter in coniferous or deciduous woods, commonly with Beech, Silver Birch or Oak.
The name ‘amethyst’ refers to the purple colouring of the young mushrooms and Laccaria means ‘lacquered’, referring to the shiny appearance of the fresh caps.
Laetiporus sulphureus
This fungus is a common find in woodlands across the UK. They are found mainly on deciduous trees, for example oak, sweet chestnut and beech. Often they are quite high up on the tree trunk, so its worth casting your eyes upwards!
The flesh of this bracket fungus has a texture similar to cooked chicken, hence the common name!
The Giant polypore (Meripilus gigantus) can form similar bracket structures. However, the underside of Giant polypore turns black when damaged, which cannot be seen in Chicken of the Woods.

Daldinia concentrica
Find this fungus growing on dead or dying wood, particularly Ash and Beech.
There are many other fungi which produce tough black crusts on deadwood, however most of these produce much smaller fruit bodies than King Alfred’s Cakes.
The common name of this fungus refers to its appearance resembling burnt cakes! As the story goes, a woman giving shelter to Alfred asked him to watch her cakes cooking. He let the cakes burn, and tried to hide the evidence by scattering them in the woodland.
This fungus also makes a great firelighter! The fruit bodies can smoulder for a long time when lit, so may also have been used to transport a flame when on the move.
Hypholoma fasciculare
This fungus grows in dense clusters on dead or dying wood, and can be found on deciduous or conifer trees.
The Brick Tuft (Hypholoma lateritium) is very similar, but typically has a darker reddish cap, and its gills are more yellow rather than the green-ish tinge of Sulphur tuft gills.
Sulphur tufts are bioluminescent, that is they glow in the dark! They don’t glow strongly, so the effect is best seen using a long camera exposure, or by shining the fruit bodies with a UV light.

Lamium purpureum
Red Dead-nettle is traditionally known as the ‘bumblebee flower’ in some British counties as bumblebees love it! Other names include ‘sweet archangel’ and ‘bad man’s posies’. Red Dead-nettle is related to the stinging nettle but has no sting – hence the ‘dead’ in ‘dead-nettle’.
Red Dead-nettle has whorls of pink-purple flowers clustered amongst leaves towards the top of the plant. The aromatic leaves are hairy, heart-shaped and have toothed edges. Some leaves near the top of the plant take on a purple tint. This plant can be mistaken for henbit dead-nettle which has similar flowers. They can be differentiated because Red Dead-nettle leaves have short petioles (leaf stalks).
Found throughout the UK, Red Dead-nettle likes arable and waste land and can also be found in gardens, hedgerows and on roadsides.
Red Dead-nettle has a long flowering season that can begin in February and last until November.
Taxus baccata
A mature yew is compelling for its dense, dark evergreen foliage and buttressed trunk that has a colour close to mahogany.
Yew has a unique and remarkable association with churchyards where it was planted over graves to protect and purify the dead, and also for more mundane reasons such as being planted on a protected site to provide wood for long bows and to keep poisonous foliage out of reach of browsing cattle. It is also used for providing decoration for churches.
Yew is concentrated in south-east and central England. It is primarily found in churchyards and woodland.
It is principally a species of well-drained chalk and limestone soils. In ancient woods it grows alongside ash, maple and beech.
The best time to spot Yew is over the winter, specifically in November, December and January.
It’s important to note that every part of the yew is poisonous except the flesh of its red berrylike fruit (the aril), although even that contains a toxic seed. The aril is slightly sweet which makes it tempting for children. Eating just a few seeds or a handful of leaves causes gastrointestinal problems, a dangerous drop in pulse rate and possible heart failure. Many victims are found dead and therefore are never able to describe their symptoms. Suicide by Yew was a way of avoiding defeat in Ceasar’s Gallic Wars.
However, Yews do contain an alkaloid named taxol which seems to be effective against ovarian, breast and lung cancers. Drug companies and research laboratories are offering to buy the foliage in bulk.
Usnea articulata
It is most common in the south west’s temperate rainforest zone.
Favouring well-lit conditions and dry, open situations, it is most often found in tree canopies or on lower branches where trees are well-lit, in woodland or on scattered trees in open moorland. You can also find it on the ground after stormy weather.
Other large, bearded lichens include Usnea ceratina, Usnea dasopoga and Usnea hirta but these lack the sausage-like lobes.
Largely restricted to south-western parts of the UK with most records in south-west England.
Microglossum olivaceum
Rare but when found usually on unimproved grassland, often mossy between late summer and autumn.
The latin name for Olive Earthtongues is Microglossum Olivaceum. Microglossum means small tongue, while olivaceum refers to the hint of olive to most of the fruitbodies (but note that the colour is very variable with some being much browner than others).
