Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures

Product Information

In the webcap group, many toxic Cortinarius toadstools are described with pictures, including the deadly poisonous Cortinarius rubellus and Cortinarius orellanus. Gymnopilus junonius, Inocybe geophylla, and Galerina marginata are also poisonous. Deaths and serious poisonings including murders result from being fed fungi from this deadly bunch. The biological kingdom of fungi is enormous, containing at least a million species and perhaps ten times that number. Fewer than 100,000 species (17,000 in Britain) have so far been described scientifically and given binomial (Genus + species) names.

Entangled Life: How Fungi Make Our Worlds, Change Our Minds

The questions grow more complicated. Mycorrhizal fungi are species whose mycelia penetrate and entangle themselves with plant roots. A symbiotic exchange occurs, in which the photosynthesising plant feeds the mycelium with carbon, and receives from it nitrogen, phosphorus and other nutrients. I nearly wrote “receives in return”. Descriptions of this relationship can barely reject the language of bargains. There is frequent adjustment. Plants funnel chemical information from the air to the fungus, whose mycelia bring similar signals to the plant from underground. In woodland, the network, involving numerous species, can be so extensive and dense that trees detect what happens to each other across long distances. Some people call this the “Wood Wide Web”. Microscopic examination and/or chemical tests are necessary to identify some of the more difficult type of fungi. See our introductory guide to microscopy and the use of chemical reagents and stains... The roles and importance of fungi When we think of fungi, we probably think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that support and sustain nearly all living systems. The more we learn about fungi, the less makes sense without them.Cook, Gareth (24 June 2020). "A Poetic, Mind-Bending Tour of the Fungal World". Scientific American.

Appropriately, Sheldrake is tentative in these descriptions, and offers a range of terms and metaphors, for none seems exactly right. Each articulation seems either too anthropomorphic or too reductive. Some expressions attribute too much intelligence, choice or even feeling to the mycelium; some too little. Sheldrake is feeling his way towards new vocabularies and concepts. A great deal of ecological thought now asks us to take more note of the relationships of interdependency that embed and sustain us, including many too large or small for unaided vision. The interpenetration of these systems raises questions about the boundaries of our selfhood. It is difficult now to think simply in terms of inside and outside, or self and not-self. Sheldrake uses the term “involution”, coined recently to shift emphasis from the evolution of separate life-forms to the emergence of these systems. I fell in love with this book. Merlin is a scientist with the imagination of a poetand a beautiful writer… This isa book that, by the virtue of the power of its writing, shifts your sense of the Human… it will inspire a generation to enter mycology."Pictures, descriptions, taxonomic history, habitat and distribution information on more than 600 fungi species are available via our Sortable Index Table... New to fungus forays? Boletales are interesting, and many are edible. Boletus edulis (above), known as Cep, Cépe, or Penny Bun Bolete (King Bolete in the USA, and Porcini in Italy) is most highly rated. Other boletes with pores include Suillellus satanas, Boletus badius, Suillus luteus, Suillus bovinus, Leccinum scabrum and Strobilomyces strobilaceus (synonym Strobilomyces floccopus). Some boletoid fungi have gills - Gomphidius roseus, Chroogomphus rutilus and Hygrophoropsis aurantiaca are examples. Paxillus species have recently been split up, too, and DNA sequencing has provided the evidence necessary for recategorisation.
