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. This book allows everyone to identify mushrooms found in Britain and Ireland. The book is illustrated with beautiful photographs throughout, featuring the species you are most likely to see.

To produce a spore print, use a fresh, mature but not over-ripe fruit body. The freshness is important because it can be difficult to obtain a print from specimens that have been kept in a fridge or allowed to dry out slightly. It is an operation that should be started immediately on returning home after a collecting expedition. Cut the cap from the stem at the apex with a sharp knife and place it gills downwards onto a piece of smooth, stiff white paper or card. Cover the cap with an inverted jar or similar cover and leave it undisturbed. Depending on the state of cap maturity, it may need to be left for anything between half an hour and 24 hours. The spores will then be discharged from the gills as described later and produce a pattern on the card; this is the spore print, and for most identification purposes the colour of the pattern on the paper, when dry, can be used. For critical genera like Russula, however, scrape the spores into a small heap with a microscope slide cover glass, flatten the heap gently with the cover glass and assess the colour of this mass of spores in daylight (take the card to a window during the daytime, because evening light in autumn and artificial light can give confusing colours). Chemical tests on the fruit body Former Head of Mycology and Plant Pathology and sometime Acting Regius Keeper at the Royal Botanic Gardens, Edinburgh] Dilute or concentrated solutions of hydrochloric, nitric or sulphuric acids. These acids are extremely dangerous chemicals and should only be used by those experienced in their handling. Microscopic features The Book of Fungi takes 600 of the most remarkable fleshy fungi from around the world and reproduces each at its actual size, in full colour, and accompanied by a scientific explanation of its distribution, habitat, association, abundance, ... Identification: A grey to fawn cap that is at first egg-shaped and then later bell shaped. The surface is smooth and splits into a few tiny scales from the apex, the edges are often wavy and split. Stem is white and hollow. Cap is around 4-8 cm across and stem is 5-15 cm tall.

The diameter to be used is the average measured in centimetres across at least two diameters of a mature cap. The height, which is used normally only with markedly conical or bell-shaped caps, is the average in centimetres of at least two heights measured from the apex to the cap edge. Cap diameter and height vary considerably with overall growing conditions, and whilst there are obviously large and obviously small types of agaric, size alone is almost never a criterion for determining the limits of a species. Moreover, the size ranges given in the species descriptions should never be considered as excluding the existence of some particularly large or small individuals. Apply a few drops of a fresh aqueous solution of 10 per cent (weight: volume) ferric chloride or ferric sulphate to the stem and observe any colour change. If it is possible to obtain a large crystal of ferric sulphate, this can be rubbed directly on the stem and so used for rapid identification of certain species of Russula in the field. It can be kept fresh when not in use by placing it in a corked tube containing a wad of cotton wool moistened with dilute ammonium sulphate. The sixth title in the bestselling Collins Guide series, this book covers the fungi of the British Isles, with considerable relevance for Europe and the wider temperate world. Leading mycological artists have been specially commissioned to ensure accurate, detailed illustrations.

Collins Fungi Guide: The most complete field guide to the mushrooms & toadstools of Britain & Ireland Whether we call them all mushrooms, as the Americans tend to do, or toadstools as we often do in Britain, they form a huge and amazing array of species. The terms mushroom and toadstool are of course very vague with no actual specific scientific meaning, encompassing both edible and poisonous species. With such a large number of species to choose from, identification can be both difficult and frustrating, and if edibility is a factor then obviously getting a correct identification is even more important; a mistake can be, and sadly has often been, fatal. Fungi are enjoyed by many people because of their beauty and intrigue. For this reason you should take care to minimise the visual effect of collecting samples.

This is because relatively few species can be named accurately in the field, other than by the most experienced collectors, and even they almost always find it necessary to collect fruit bodies for close inspection. Most fungi, moreover, require microscopic examination and sometimes simple chemical tests too, either to verify an identification based on superficial characters or, sometimes, to identify them at all. The legality of collectingAdd 8 ml concentrated sulphuric acid to 3 ml water and dissolve 1 g pure vanillin in this. A characteristic colour change occurs in some groups when this is applied to the stem. Concentrated sulphuric acid is an extremely dangerous chemical and the reagent must be prepared with the greatest care and only by those experienced in its use. 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: Remove the specimens carefully from the substrate, noting especially if the stem base is rooting (inserted deeply into the ground, rather like a carrot root). Make a record of any features that are immediately obvious and striking (a hairy cap, a smell of almonds or a bright red colour for example) and also those characters that change on handling (such as a colour change similar to bruising where the tissues have been touched, or an aroma that becomes suddenly apparent). Whenever possible, try to take at least one immature fruit body but remember that without some fully mature individuals identification will usually be impossible. It is much better to place only one collection in each container for bringing home; many toadstools look remarkably similar, especially when seen apart from their habitat, and trying to relate a mixed collection to one species can cause endless frustration. The need not to mix collections is even more important when collecting fungi to eat because an inedible or poisonous species can so easily be tossed into the pan along with the edible ones. Identification: Has a blue to violet tinged cap and gills when young, however older caps turn tan or grey from the centre. Gills are crowded and grow into the stalk and fade to brown as the mushroom matures. The cap is roughly 5-15 cm across, and the stem 5-10 cm tall. The vital role of fungi in the ecology of grasslands is becoming more widely appreciated, sparking an increasing interest in identification.

The manifestations of a universal veil are somewhat different. Universal veils are not formed by all agarics but when present they envelop the entire developing ‘button’ and as the fruit body expands and matures, fragments of the veil remain as flakes on the cap surface, often in contrasting colour to the remainder of the cap. More significantly, however, the veil remains enveloping the base of the stem as a structure called a volva, the presence of which is characteristic of certain genera. The volva takes one of two main forms: when its tissues adhere closely to the stem base, it is called adherent and its surface may be loose and scaly, powdery or, sometimes, marked with characteristic concentric zones; when the volva envelops the stem base like a loose bag, it is said to be free and its tissues may then vary from very fragile to fairly tough and membranous. Many people come into mycology via a desire to try eating something a little more exotic than the shop bought mushroom. There are many edible species and they can have tastes and textures quite unlike the cultivated species. Hunting for edibles can be a wonderful experience but there are several rules to follow if your hunt is to have a happy outcome:

Although the Law and its interpretation is rather complex, and no prosecutions have yet been brought, it is clear that deliberately and knowingly collecting magic mushrooms is illegal unless you intend immediately to destroy them or pass them to someone who is licensed to hold them. Licences are held by such bodies as the two Royal Botanic Gardens at Kew and Edinburgh but are unlikely to be issued to individuals. If you collect magic mushrooms without knowing what they are, it appears you will only commit an offence if you retain them once they have been identified. You will not be committing an offence of possession if magic mushrooms are growing uncultivated on your premises. 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). 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.

Next up, Geoffrey Kibby, whose new photographic identification guide to the Genus Amanita is the fourth in a series of full colour fungi identification monographs, and is out now. In the following article Kibby discusses the finer points of mushroom identification: Spores and most other features of microscopic interest do retain their form more or less indefinitely and can be examined at leisure after small pieces of dried tissue have been macerated in warm water, Melzer’s reagent ( see here), methylene blue or cotton blue (see here). It should be remembered nonetheless, that for some fungi, such as those in the genera Lactarius and Russula, features like spore print colour, taste and smell are of such importance for identification that accurate naming of dried specimens without detailed notes on the fresh material is often impossible. Last week we published a blog post with advice on purchasing a hand lens, plus a useful comparison chart showing the various lenses you can buy from NHBS. The second edition draws on an additional three years of surveying done over a wider area, adding 23 new species to the 177 already described in the first edition Fungal nutrition is a complex subject but one aspect of it is nonetheless of particular importance in relation to their occurrence in the field. Anyone who has ever collected toadstools will have noted that many, perhaps most, occur in particular types of woodland, beneath particular types of tree or consistently in company with certain types of plant. This is not mere chance, nor the result of two species requiring a similar ecological niche. It is because of an intimate association called a mycorrhiza, which means that under certain circumstances the one cannot exist, or can do so only inadequately, without the other. A mycorrhiza is a symbiotic association between fungal hyphae and the roots of higher plants, and also, to some extent, of some Pteridophytes (ferns and their allies) and the rhizoids of Bryophytes (mosses and liverworts). The fungal mycelium forms an outer sheath around the fine rootlets and this can be seen if the rootlets are examined closely with a lens. Penetration of fungal hyphae into the root is limited and occurs only between the cells of the cortex. Precisely how the mycorrhizal mycelium assists its host plant, and vice versa, is still imperfectly understood, but it seems that the fungus obtains much of its necessary supply of carbon from the roots and, in return, acts as an intermediary in the uptake of nutrients such as nitrogen, phosphate and potash from the soil. The mycorrhizal fungus seems better able to achieve this uptake, especially from poor soils, than does the plant acting on its own. The naming and classification of fungiFungi 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. Fungi are also uniquely distinct in relation to their mode of nutrition. Plants photosynthesise, a process in which solar energy is absorbed by green chlorophyll and used to bring about the formation of nutrient substances from the raw materials of atmospheric carbon dioxide and water. No fungus can photosynthesise, and even the few species that sometimes display a green fruit body colouration or green spores do not contain chlorophyll. Fungi also have a mode of nutrition different from animals in that while animals eat, digest and then absorb the digested matter internally, fungi secrete enzymes externally from their hyphae into the environment where organic matter is broken down and then absorb the resulting chemicals from there. Like animals therefore, fungi are dependent for their nutrient source on other organisms, either living or dead. And this dictates where they grow: typically on soil, using humus and plant remains for nutrition; directly on wood or other plant matter; or sometimes parasitically on still living plants. 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.
