How to...

identify the common fungi of autumn

Pick up any guide to British fungi and one of the first things that strikes you is just how many different shapes, sizes and colours of species there are - over 2500 larger species in the UK! So how do you begin to get familiar? Justin Smith is a mycologist (fungi expert) who works with us on our botanical training programmes, and here he passes on top tips to help you identify ten of our more commonly encountered species.

Identifying spore-colour
This is easily done by cutting the stem off and laying the cap, gill side down, on white paper and leaving it for a few hours. A pattern will form, like a bicycle wheel, showing the spore colour.

Useful fungi guides
Justin recommends books with good illustrations and descriptions with as wide a range of species featured as possible, such as:

Mushroom and other Fungi - Roger Phillips (Pan 1981)
Mushrooms and Toadstools of Britain and Europe - R Courtecuisse and B Duhem (Collins Field Guide 1996)

There is also a local fungus group which leads forays and helps in identification. Details from Justin Smith 07810694835.

What's in a name?
In the past the word mushroom denoted fungi that was useful to man ie edible - and a toadstool was most definitely not! Nowadays, however, use of these words is archaic and mushrooms and toadstools are known as gill fungi.

Amethyst deceiver A dark violet species found on beech wood litter, and named for its amethyst colour and similarity to many other similarly-coloured species. Like the scarlet hood this is another white-spored species.   Scarlet hood A bright red species, one of a group of 'wax caps' typically found in grazed meadows. They can be spotted from quite a distance as they occur in swarms of scarlet caps in autumn.
Beef steak fungus A large fleshy bracket fungus found on old, living oaks. Typically 'flesh-like' in appearance , yielding a red juice. The Spanish call it cow's tongue!   Shaggy scale cap Another tuftal species, tawny yellow in colour, but both the cap and stem are covered in coarse scales. The shaggy scale cap is typically found on beech and has rusty brown spores. It forms colonies as large as the honey fungus, up to one metre wide.
Clouded funnel cap The clouded funnel cap differs from many other 'mushroom' types in being funnel-shaped rather than umbrella-shaped. It is a large grey species that forms fairy rings in woodland in late autumn. Again, the clouded funnel cap has white spores.   Stump puffball These suggest unopened 'mushrooms' but release their spores via an opening in the cap and not from their gills. It grows in cluster on tree stumps.
Ear fungus A reddish brown fungus shaped like an ear, jelly-like in texture when fresh and hard and crusty when dry - it can revive on re-moistening. Very commonly found on dead elderberries.   Sulphur tuft Also forms large tufts at the base of trees, but this species feeds on dead wood only. The caps are much smaller than the honey fungus and bright sulphur yellow in colour, hence the name. This species has purple-brown spores.
Honey fungus A very common parasite of many trees and the bane of both the forester and gardener, it typically forms huge tufts of honey-coloured 'mushrooms' at the base of the host tree. The white spores of this species can often be seen on the caps within the tuft (see below for how to find the colour of spores!)   Velvet shank A late autumn to winter species, typically most common on dead elm trees in hedgerows. The velvet shank also forms tufts but has a greasy orange cap with dark brown velvety stem. Like the honey fungus it also has white spores.

Note: although the above fungi are not poisonous, never eat fungi without consulting an expert.
