White Saddle (Helvella crispa) is a distinctive and widespread fungus found across Britain, particularly from late summer through autumn. It is readily recognised by its irregular, saddle-shaped cap, which is typically white to pale cream and divided into several wrinkled and wavy lobes. The cap sits on a pale, deeply ridged and furrowed stem, giving the entire fruiting body a somewhat crumpled appearance.
It occurs in a variety of habitats, although it is particularly associated with deciduous woodland and areas near trees. It can also be found along woodland edges and tracks, in hedgerows, parks, gardens and grassland, especially where the soil is calcareous. The fruiting bodies are usually encountered singly or in small groups.
White Saddle is generally regarded as edible when thoroughly cooked, but it is not considered a highly desirable edible fungus. Identification should be certain before consumption because other saddle fungi can look similar, and some Helvella species may contain harmful compounds. It has a mild, generally pleasant fungal or earthy fragrance and is best regarded as a fungus of interest for its distinctive appearance rather than for its culinary qualities.
White Saddle (Helvella crispa)
White Saddle (Helvella crispa) is one of Britain's most distinctive saddle fungi. Its pale, convoluted fruiting body can look remarkably like a small piece of crumpled white or cream-coloured fabric rising from the woodland floor. The unusual appearance makes it easier to recognise than many of the smaller fungi encountered during the autumn months, although its shape can vary considerably between individual specimens.
It is a widespread fungus in Britain and Ireland and is particularly associated with broadleaf woodland. Beech and oak are among the trees with which it is commonly found, and it is frequently encountered beside woodland paths and other areas of disturbed ground. Despite its distinctive appearance, it can be surprisingly easy to overlook when growing among fallen leaves and other woodland debris. On a bright day, however, its pale fruiting bodies can stand out conspicuously against the darker woodland floor.
What does White Saddle look like?
The most obvious feature of White Saddle is its irregular, saddle-shaped cap. Rather than forming a conventional mushroom cap, the upper part of the fungus consists of several lobes that are folded, twisted and curled into an elaborate saddle-like structure. There are usually two or three major undulations, accompanied by numerous smaller wrinkles and contortions.
The cap is generally white, cream or pale yellowish-cream, although individual specimens can sometimes develop pinkish or pale ochre tones. The upper surface is usually relatively smooth, while the underside can be slightly downy. The combination of the pale colour and heavily folded shape gives White Saddle a distinctive appearance that is quite unlike the familiar rounded caps of most woodland mushrooms.
The cap is typically around 3–8 cm across, although its size and shape are quite variable. It is supported by a pale stem that is often similar in colour to the cap. The stem is particularly distinctive because it is deeply furrowed and fluted, with prominent longitudinal ridges and channels. It is hollow and has thin, elastic flesh. The stem is generally around 4–8 cm long and 2–4 cm wide.
The combination of a pale, irregular saddle-shaped cap and a deeply grooved white stem is the key to recognising this species in the field.
Why is it called White Saddle?
The common name is a straightforward description of the fungus's appearance. The pale colour accounts for the White part of the name, while the strongly folded cap resembles a miniature saddle, giving rise to White Saddle.
The scientific name is equally descriptive. The species name crispa comes from Latin and means curled or wrinkled, referring to the contorted and folded appearance of the cap. The genus name Helvella is an ancient term associated with an aromatic herb.
Fungi in the genus Helvella are also sometimes collectively known as Elfin Saddles, a name that reflects the strange saddle-like appearance of many species in the group.
Where does White Saddle grow?
White Saddle is principally a woodland fungus and has a particular association with broadleaf trees. It is especially associated with beech and oak, and specimens are often found on or close to woodland paths.
It can occur in several different situations, including:
-
Deciduous woodland
-
Mixed woodland
-
Beech woodland
-
Oak woodland
-
Woodland edges
-
Woodland paths and tracks
-
Hedgerows
-
Grassy areas beneath or close to trees
-
Parks and gardens
-
Other areas of disturbed ground
It is particularly noticeable beside well-used paths, where the vegetation and leaf litter have been disturbed. Finding White Saddle beside a woodland path is therefore not unusual.
The species is believed to be mycorrhizal, meaning that it forms an association with the roots of trees. This may help explain its close relationship with broadleaf woodland and its frequent occurrence beneath or near trees.
When does White Saddle appear?
White Saddle is primarily a fungus of summer and autumn. Its fruiting bodies can therefore be encountered during the warmer part of the year and into the autumn fungi season.
The appearance of individual fruiting bodies is relatively short-lived compared with the perennial trees and plants among which they grow. The visible saddle is the reproductive fruiting body of the fungus, produced when conditions are suitable for the fungus to release its spores.
After appearing above ground, the fruiting body eventually deteriorates and disappears, while the underground fungal organism can remain associated with its habitat.
A fungus that is easy to recognise
White Saddle is fortunate in that its appearance provides several useful identification features at once. The pale colour immediately distinguishes it from many of the darker saddle fungi, while the strongly wrinkled and irregular cap gives it its characteristic shape.
The deeply furrowed stem is another valuable feature. When viewed from the side, the combination of the pale saddle-like cap and the heavily fluted stem is particularly distinctive.
Nevertheless, colour alone should never be relied upon when identifying a fungus. White Saddle belongs to a genus containing several species with similarly shaped fruiting bodies, and individual specimens can be surprisingly variable.
One species that can cause confusion is Elastic Saddle (Helvella elastica), which can also have a saddle-shaped cap but generally has a smoother, tougher stem without the pronounced channels seen in White Saddle. Fluted Bird's Nest Fungus (Helvella lacunosa) is another member of the genus, but its cap is generally greyish-brown to black rather than the pale colour characteristic of White Saddle.
White Saddle and other saddle fungi
White Saddle belongs to the family Helvellaceae and is an ascomycete fungus, rather than one of the more familiar basidiomycete mushrooms. This is an important distinction because fungi that look superficially like mushrooms can belong to quite different groups.
Its scientific classification is:
Kingdom: Fungi
Phylum: Ascomycota
Class: Pezizomycetes
Order: Pezizales
Family: Helvellaceae
Genus: Helvella
Species: Helvella crispa
The species has also had an interesting taxonomic history. When Giovanni Antonio Scopoli described it in 1772, he placed it in the genus Phallus, using the name Phallus crispa. This meant that he considered it related to stinkhorns. It was subsequently transferred to Helvella by Elias Magnus Fries in the nineteenth century. White Saddle is not actually closely related to stinkhorns; stinkhorns are basidiomycete fungi, whereas White Saddle is an ascomycete.
How common is White Saddle?
White Saddle is considered common in Britain and Ireland and is widely distributed across mainland Europe. It has also been recorded in parts of North America.
Although it is common, that does not mean that every woodland walk will produce a sighting. Fruiting can depend on local conditions, the presence of suitable trees and the amount of suitable habitat. Its tendency to grow among leaf litter can also make it less conspicuous than its pale colouring might suggest.
Look particularly carefully along woodland paths during the summer and autumn. The pale caps can sometimes be spotted from several metres away, especially where they contrast with dark soil, brown leaves or green vegetation.
The smell of White Saddle
White Saddle is not noted for having a strong or particularly distinctive smell. Its odour is described as faint, and there is no distinctive taste.
This is useful to bear in mind when identifying the species. Unlike some fungi whose smell is one of their most obvious characteristics, White Saddle is principally identified from its appearance, particularly its pale, convoluted cap and deeply furrowed stem.
Is White Saddle edible?
White Saddle has traditionally been described in some field guides as edible when thoroughly cooked, although it is generally regarded as a poor-quality edible fungus. There are important reasons to be cautious about treating it as a food species.
White Saddles have been reported to cause stomach upsets when insufficiently cooked. Thorough cooking is therefore considered necessary by sources that discuss the species as edible. However, even when cooked, the fungus is not generally regarded as particularly worthwhile from a culinary perspective. Its texture and flavour offer little incentive to take unnecessary risks.
There have also been concerns about potentially harmful compounds occurring in Helvella fungi. Consequently, White Saddle is better regarded as a species to admire and photograph rather than one to collect for the pot.
Anyone considering eating a wild fungus should be absolutely certain of its identification and should use current specialist guidance rather than relying solely on a photograph or a general website. Similar-looking fungi can have very different properties.
White Saddle in the woodland
One of the pleasures of encountering White Saddle is the way its unusual appearance contrasts with the familiar surroundings in which it grows. A woodland floor is often dominated by relatively predictable shapes: rounded mushroom caps, fallen leaves, mosses, twigs and decaying wood. White Saddle breaks that pattern with its strange, pale and heavily folded fruiting body.
Its resemblance to a tiny saddle is especially apparent when the fruiting body is viewed from the side. The folds and lobes can give individual specimens an almost sculptural appearance, with no two specimens necessarily looking quite alike.
The fungus can also change considerably as it ages. Young fruiting bodies may appear relatively compact, while older specimens can become increasingly expanded, distorted and discoloured. This variation is one reason why photographs in field guides can sometimes make identification appear easier than it is in practice.
Looking for White Saddle
If you want to find White Saddle in the wild, deciduous woodland is a good place to start. Concentrate on areas containing mature broadleaf trees, particularly beech and oak, and examine the ground carefully around the edges of paths.
The best time to look is during the summer and autumn fungi seasons. A slow walk is much more productive than simply passing through the woodland at normal walking speed. Look for pale cream or white shapes among fallen leaves, particularly where the ground has been disturbed.
Once you recognise the characteristic saddle shape, White Saddle becomes considerably easier to spot. Its pale colour can make it surprisingly conspicuous in the right conditions, although specimens growing among pale leaves may blend in.
It is also worth examining the stem rather than concentrating entirely on the cap. The deeply fluted, channelled stem is one of the most useful characteristics separating White Saddle from some of its relatives.
A distinctive British fungus
White Saddle is a good example of why fungi can be so fascinating. It is common enough to be encountered by ordinary woodland walkers, yet its appearance is sufficiently unusual to attract attention once you know what to look for.
Its pale, saddle-shaped cap, convoluted lobes and deeply furrowed stem make it one of the more recognisable members of the British Helvella genus. Its preference for broadleaf woodland, particularly beneath beech and oak, also makes it a characteristic species to look for during summer and autumn woodland walks.
Although it has sometimes been regarded as an edible fungus, its poor culinary reputation and the potential risks associated with consuming Helvella species mean that there is little reason to collect it for food. Its real appeal is as a fascinating woodland fungus to observe, photograph and learn to identify.
For anyone developing an interest in British fungi, White Saddle is an excellent species to become familiar with. Once you have learned its distinctive combination of a pale, wrinkled saddle and strongly fluted stem, you are likely to start noticing it in places where you previously walked straight past it.
