Product Information

Note: we cannot stress strongly enough the caution with which you should approach mushroom identification. Some mushrooms are edible, but some are deadly, and identification can be very difficult. As Geoffrey Kibby says below, if in doubt, throw it out!). Other stem features have manifestations on the stem and, to some extent, on the cap too; these are the presence or absence of veils – more or less filmy sheets of tissue produced on the fruit bodies of some agaric species. They are of two types, partial veils and universal veils. A partial veil covers the gills of an agaric fruit body as it emerges from the substrate, stretching from the cap edge to the stem. As the cap grows and expands, this veil tears in one of two main ways. An arachnoid (spider or cobweb-like) veil splits radially leaving fibrils on the cap edge and sometimes adhering across the gills too. By contrast, a membranous veil tears concentrically around the cap, sometimes leaving flaps of tissue conspicuously on the cap edge and more importantly a ring of tissue (called the ring) on the stem itself. In many fungi the ring is barely detectable but in others it forms a very obvious feature, important in identification. The ring may take several forms; if it joins only loosely to the stem, it is called movable, if more tightly adhering, attached. If it is on the upper part of the stem, a ring is called superior; if on the lower half, inferior; a ring with a cotton wool-like roll of tissue on the underside is referred to as double. Sometimes there is no proper ring, only a ring-zone or slightly rougher tissue and contrasting colour on the stem. Established permanent grasslands, meadows, commons, lawns and parkland are very different however. These are relatively undisturbed habitats, although the grass itself may be grazed or mown. The soil temperature is relatively uniform, protected by the grass swards, but may be prone to drying out in summer. Among major agaric genera, Agaricus, Clitocybe and Hygrocybe are especially frequent on these grasslands, and representatives of all groups that do not have an obligate mycorrhizal association with trees or that depend on wood as nutrient source may be expected. The sub-division of grasslands is less straightforward than that of woodlands, and although certain well-defined types can be recognised, there are less obviously characteristic mycobiotas in each. 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 Digital Reads A Curse For True Love : the thrilling final book in the Once Upon a Broken Heart series

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: Ocr tesseract 5.0.0-1-g862e Ocr_detected_lang en Ocr_detected_lang_conf 1.0000 Ocr_detected_script Latin Ocr_detected_script_conf 1.0000 Ocr_module_version 0.0.14 Ocr_parameters -l eng Old_pallet IA-NS-2000541 Openlibrary_edition Living organisms are given names and are classified into groups; fungi are no exception. The scientific names used for organisms today are based on a binomial or two-name system based on Latin and other languages and using Latin grammar derived from one devised by the Swedish biologist Linnaeus (Carl von Linné, 1707–1778). The binomial of each organism does more than signify its uniqueness, however, as it also attempts to indicate its relationship to other similar forms. Whilst each group of basically identical individuals is called a species, designated by the second of the two names, the larger groups to which similar species are considered to belong are called genera (singular genus) and it is the genera that contribute the first name. So, the fungus genus Lepiota includes species like Lepiota lilacea, Lepiota magnispora and Lepiota obscura. The specific or trivial name often attempts to give some information about the organism, for example lilacea signifies a lilac-coloured fungus and magnispora one with large spores, although sometimes, as in obscura, it does no more than recognise some undefined peculiar feature. Many species can only be distinguished with certainty by using a microscope to examine their spores and other microscopic structures, or by the application of specific chemicals to produce colour reactions. More technical monographs are needed for these.

Collins Fungi Guide: The most complete field guide to the mushrooms & toadstools of Britain & Ireland Supply information to local and national databases and retain ‘voucher specimens’ for deposit in museum collections. 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.

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. 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 featuresThe list of those species that are classed as magic mushrooms is only provisional and there is uncertainty about the validity of some of the chemistry on which it is based. Nonetheless, it does have legal standing. The relevant species are indicated in the text of this Guide. Equipment For collecting

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:Finally, it should be noted if the gills are deliquescing or self-liquefying and turning inky, a characteristic of many species in the genera Coprinus, Coprinopsis, Coprinellus and Parasola.

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.Mushrooms is my personal take on the world of fungi in Britain, about the pleasures of searching for mushrooms and toadstools, and why they matter. I have written it as a narrative, in current TV parlance as a ‘journey’, beginning with the extraordinary diversity of fungi and the ways in which they exploit the natural world to the history of the fungus foray and the controversy over gathering wild mushrooms for the pot. In the process I zoom in on the nature of names, both Latin and English, at the places which hold the greatest diversity of fungi, and our attempts to conserve rare and vanishing fungi. It is, I hope, a refreshing and amusing look at this ‘third world’ of life, written without jargon and in lively style. I hope it can be read with pleasure by anyone. It is full of lovely colour photographs. A few types of Basidiomycete such as the jelly-like members of the family Dacrymycetaceae do not dry satisfactorily, and although they can be preserved in alcohol, formaldehyde or other liquid, the results are not very satisfactory. Most types of Ascomycete, apart from a few terrestrial species, are much less fleshy than most large Basidiomycetes and will dry very adequately in the air at room temperature. Identification 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.
