folded sheets of coloured figures representing the commonest 

 edible and poisonous species ; subsecjuent editions were called 

 for in quick succession, the fourth being issued in 1879. It 

 is now, however, out of print. 



Many of the notes and papers published during these early 

 years dealt with plant diseases due to the attacks of parasitic 

 fungi, and in 1875 the Royal Horticultural Society shewed 

 its appreciation of his work by awarding him the Knightian 

 Gold Medal for his researches into the life-history of the po- 

 tato disease fungus. In 1884 he issued a notable contribution 

 to the Fungologv of the British Isles : — " Diseases of Field 

 and Garden Crops, chiefly such as are caused by Fungi." 

 The book, as he tells us, embodies the reports of a series of 

 addresses given at the request of the officers of the Institute 

 of Agriculture at the British Museum, S. Kensington. 

 TAventy years earlier, Cooke had published " Microscopic 

 Fungi," but Smith treated the whole subject in its economic 

 aspect : he gives in detail the life-history of the parasites, and 

 suggests means to stay if not entirely to remedy the diseases. 



Worthington Smith's systematic studies and publications 

 were also of very great importance. The " Clavis Agarici- 

 norum, an analytical Key to the British Agaricini, with char- 

 acters of the genera and subgenera," was prepared for the 

 Woolhope Club and published as a thin octavo volume or 

 pamphlet in 1870. Much of it is included in his subsequent 

 works. In 1891 he published the " Outlines of British 

 Fungology, Supplement," thus bringing the earlier volume 

 by Berkeley up to date. A Guide to Sowerby's Models of 

 British Fungi in the British Museum (Natural Historv) was 

 issued in 1893 and was reissued in 1908. It is a remarkably 

 good introduction to the study of the larger fungi. The more 

 recent Museum Guide to drawings of Field and Cultivated 

 Mushrooms and Poisonous or Worthless Fungi often mis- 

 taken for Mushrooms" (1910), is accompanied by a large 

 folded sheet of coloured drawings of the Mushroom in its many 

 forms. The largest and most important of his systematic 

 works is, however, the " Synopsis of the British Basidiomy- 

 cetes," also published by the British Museum (1908). It 

 provides a standard and reliable work on the subject, but 

 suffers somewhat from necessary compression. 



Smith's skill as a botanical artist was in constant requi- 

 sition, his studies of orchids and other plants appeared from 

 time to time in the Gardener's Chronicle between the years 

 1875 and 1910.* With his illustrations of Bentham's British
