Peter Darbishire Orton (28 January 1916 – 7 April 2005) was an English mycologist and schoolteacher who became a leading authority on British fungi, particularly agarics (mushrooms and toadstools).
Background and education
Orton was born in Plymouth, Devon, the son of marine scientist J. H. Orton. He was educated at Oundle School and Trinity College, Cambridge, where he read Natural Sciences, Music and History, receiving his degree in 1937. He then studied at the Royal College of Music, with his studies interrupted by wartime service in the Royal Artillery. After completing his studies, he obtained a position as a music teacher at Epsom College in Surrey.
Researches in mycology
Orton became interested in fungi through fellow amateur A. A. Pearson, who was also a keen musician. Specializing in agarics, Orton developed considerable expertise in identifying species. In 1955, he received a Nuffield Foundation grant to work with Dr R. W. G. Dennis, head of mycology at the Royal Botanic Gardens, Kew, and F. B. Hora at Reading University on a revised checklist of British agarics and boletes. The resulting New Checklist, published in 1960, was accompanied by 300 pages of descriptive and revisionary notes by Orton entitled Notes on Genera and Species, which included new species. It remained the standard reference work for 45 years.
In 1960, Orton took up a position at the newly opened Rannoch School in Perthshire, Scotland, where he taught biology, English, and music. He remained there until his retirement in 1981. During this period, he published many papers on Scottish agarics, particularly those collected in the Caledonian pine woods around Rannoch. He also contributed, with Prof. Roy Watling, to the British Fungus Flora series, published by the Royal Botanic Garden, Edinburgh. He frequently visited his friend and fellow mycologist T. J. Wallace in Membury, Devon, publishing a number of new agaric species from Dawlish Warren and other Devon localities.
In 1986, he moved to Crewkerne, Somerset, where he continued to collect and publish on agarics, his last paper appearing in 1999.
Legacy
Orton published extensively on British and European agarics and boletes, describing well over 100 species new to science from the British Isles. The agarics Cortinarius ortonii and Entoloma ortonii are named after him. His collections are retained in the mycological herbaria at the Royal Botanic Garden, Edinburgh, and the Royal Botanic Gardens, Kew.
The standard author abbreviation P.D.Orton is used to indicate this person as the author when citing a botanical name.
