John Wright is the author of the River Cottage Handbooks Mushrooms, Edible Seashore and Hedgerow. As well as writing for national publications, he often appears on the River Cottage series for Channel 4.

He gives lectures on natural history and every year he takes around fifty 'forays' showing people how to collect food - plants from the hedgerow, seaweeds and shellfish from the shore and mushrooms from pasture and wood. Over a period of twenty years he has taken around five hundred such forays.

Fungi are his greatest passion and he has thirty-five years' experience in studying them. John Wright is a member of the British Mycological Society and a Fellow of the Linnaean Society. He lives in rural West Dorset with his wife and two teenage daughters.
