Collins Fungi Guide: The most complete field guide to the mushrooms and toadstools of Britain & Ireland

Product Information

Fungi are not related to plants or animals because they differ from them in many important ways. Whereas the basic structural elements of plants and animals are cells which, en masse, form tissues, fungi are built up of uniquely different microscopic tubular thread-like bodies with multiple nuclei called hyphae; and collectively hyphae form, not tissue, but mycelium (although the word ‘cell’ is used widely in relation to small fungal structures that look like cells). The reproduction of fungi also differs greatly from plants in that they produce, not seeds, but microscopic structures called spores. Note the relationship of the fruit bodies one to the other. This is especially important with agarics which may occur as solitary individuals, attached to each other in various ways in tufts or clumps, or trooping (groups of isolated individuals growing close together but not obviously attached). Identification: One of the most iconic toadstools depicted in fairy-tale illustrations. It has a shiny, scarlet red or orange cap with white wart-like spots dotted across. Cap is 8-20 cm across. The gills are white and free, and the stem is swollen with rings of scales. At home, it is possible to begin a systematic examination of your specimens, but whilst numerous macroscopic features of the fruit bodies and microscopic details of their structure can be recorded, not all are needed to identify every fungus and each individual species description in this book uses only some of them therefore. The basis of this account is the identification of agarics which will comprise the bulk of the harvest from most collecting expeditions. Additional and different features needed for other groups are described here.

Identification: Are cup-shaped and scarlet, however can also be bright orange. Stems attach to the leaf litter making them appear as hollow bowls lying on the woodland floors. Cups are roughly 4cm across. Collins Fungi Guide: The Most Complete Field Guide to the Mushrooms & Toadstools of Britain & Ireland From mould to yeast, fungi are a diverse kingdom with over 15,000 species in the UK. Fungi are made up of different microscopic thread like bodies called hyphae, and collectively hyphae form mycelium. Mushrooms or toadstools are the reproductive, umbrella shaped fruiting bodies of certain fungi. These organisms can be found in almost every natural habitat, but more kinds of macro-fungi tend to be found in woodlands, as they provide a rich and continuing nutrient source and a wide range of microhabitats. Some fungi cannot be identified without a microscope, however those in this blog can be identified using macro characteristics displayed by the fruiting body. Most are umbrella or mushroom shaped with gills on the cap underside. Below are some key characteristics to look out for when identifying:Fungi are able to exploit most of the natural – and many of the artificial – raw materials of the world as nutrient sources; and to tolerate most of the environmental variables the earth can offer. Of all the natural habitats able to support life of any type, almost all are inhabited by some species of fungi. But whilst many genera of larger fungi certainly occur predominantly in one type of habitat, there are few that are wholly characteristic of individual types of woodland, grassland or other community. Nonetheless, there are certainly some fungal genera, and, more significantly, some associations of genera, that do give each habitat a characteristic mycobiota. Amanita, Lactarius and Russula for instance, which are mycorrhizal associates of trees, are predominantly woodland genera, while Hygrocybe is usually found in grassland. And a species list including Mycena capillaris, Russula fellea, Craterellus cornucopioides and Boletus satanas conjures up an image of a beech wood to a mycologist in much the same way as a list including bramble, dog’s mercury, foxglove, holly and violet helleborine might to a botanist. Woodlands Always remember that it is far better to identify with certainty ten species and so enrich your fund of knowledge and experience than return home wastefully with fifty or more unknowns, most of which there will never be any prospect of naming. Within these broad divisions, however, there is a wide range of environments. Broad-leaved woodland for instance embraces such disparate habitats as the almost pure stands of beech on the chalk downs with their extremely sparse ground flora, the rich oak wood with a ground flora dominated by early season species like blue-bells that flower before the canopy closes, and the carr, dominated by alder and willows and with almost permanent standing water. Copses and hedgerows are among several other more specialised types of woodland habitat. Each woodland type will be considered briefly in turn. Over much of Britain, mixed broad-leaved woodland, containing greater or lesser numbers of oaks, beech, limes, hornbeam, elms, birches, ash and alder, is the native vegetation type. Many fungi are associated with particular types of broad-leaved tree, and some tend to occur only in more or less pure woodland of individual species – Russula fellea, for example, occurs almost exclusively in old beech woods. Others, like Leccinum scabrum, which is always found with birch, noticeably goes wherever the tree goes, whether in pure or mixed woodland, in copses or as isolated individuals in parkland. Birch woodland and birch trees in general have quite characteristic fungal associates and there are perhaps more common species invariably associated with birches than with any other single tree genus or species. Other fungi by contrast are found in company with any of a range of broad-leaved trees. Many kinds, for instance, occur commonly with both beech and oaks; old broad-leaved woodland, such as that in the New Forest, Hampshire, which contains both these types of tree, probably supports the richest diversity of fungal species to be found in any British habitat.

Firstly, let’s be quite clear: there are an awful lot of fungi! Just including those generally referred to as the larger fungi – those just a few millimetres across all the way up to species that can reach a metre or more – there are around three thousand species recorded in Britain. The identification of fungi is not inherently any more difficult than the identification of other organisms but it requires a degree of patience and there are a number of unique factors. One major problem lies with the ephemeral nature of most fungal fruit bodies and the fairly irregular appearance of some from season to season. Thus, in many instances, there are only a few weeks each season in which to practise identification and some species may only be seen once every few years, even in the same locality. Beginners should take comfort therefore from the fact that even experienced field mycologists have to re-learn a great deal each autumn. Only the professional or very serious amateur with access to a fungal herbarium has year-round availability of material for study.

Forget about the ‘little brown fungi’ for now. Try getting to know an accessible group such as the waxcaps or the boletes, or the puffballs and their ‘relatives’. It will teach you a lot about the differences between species and the places to look for them.
