50 PROCEEDINGS OF THE 



banks of tlie Amazon and also visited Peru, Ecuador, Colombia, and 

 tlie AVest Indies. On his return to En-^'laiid he took up teaching, 

 and he continued his botanical work, making a special study of 

 Cryptogams. His artistic powers became manifest through the 

 pubhcation of his beautiful drawings in Spruce's 'Hepatiese 

 Amazonicje et Andinoe.' 



During this period of his life Massee came into contact with the 

 late Dr. M. C. Cooke, and under his guidance made great progress 

 with the study of fungi and plant diseases, a subject in which he 

 was alreiidy much interested. In later life he gracefully acknow- 

 ledged his indebtedness to Cooke by dedicating to him his 

 'European Agaricacese' (1902). Although he liad puMished several 

 important morphological and systematic papers, Massee's note- 

 worthy contributions to mycology began in 1891 with the 

 appearance of his ' British Fungi, Phycomycetes and Ustilagineae.' 

 In 1892 he published his ' Monograph of tlie Myxogastres.' In the 

 same year appeared his first volume of the 'British Fungus Flora,' 

 a work which has perhaps been the most useful of any of his 

 systematic treatises. Unfortunately four parts only of this were 

 published. 



Massee was appointed to the Kew staff in 1893. He succeeded 

 M. C. Cooke in charge of the Cryptogamic Department of the 

 Herbarium, and held the post till his retirement. 



It was witii the completion of his work for the 'British Fungus 

 Flora' that Massee appears to have turned seriously to pathology, 

 papers on tliis subject appearing continuously after 1895. Up to 

 the year 1899 the two works on plant diseases available for 

 English workers were AVortliington Gr. Smith's ' Diseases of Farm 

 and Garden Crops,' and the most useful translation of vonTubeuf's 

 ' Pflanzenkrankheiten ' by AVilliam G. Smith. The former was 

 very limited in its scope, and the latter, though comprehensive, was 

 scientific and technical and lacked the advice as to remedies so 

 eagerly sought for by gvowers. Massee's ' Text-Book of Plant 

 Diseases,' published in 1899, aimed at supplying both the means of 

 recognition of diseases and the methods of their control, and, 

 covering a large range of plants, it at once took front rank in the 

 literature of the subject. It has been very largely used by both 

 botanists and horticulturists, and a second edition was issued in 

 1903. The work brought the author into toucli with pathologists in 

 all parts of the woi-ld, and papers on tropical and colonial diseases 

 figure largely among the vast number of publications on plant 

 diseases which he subsequently produced. In 1910 his other well- 

 known work 'Diseases of Cultivated Plants and Trees' appeared. 



Despite his output on phytopathology Massee found time to 

 continue to produce works on systematic mycology. ' European 

 Agaricacese,' a concise and useful synopsis, appeared in 1902, and 

 the semi-popular ' British Fungi and Lichens ' in 1911. The more 

 general volume 'A Text-Book of Fungi' was published in 1906, 

 and his last work, ' Mildews, Kusts, and Smuts,' written in con- 

 junction with his daughter^Miss Ivy Massee, appeared in 1913.
