of the smaller size of the ascospores, which Sawada finds to meas- 

 ure 12-13 X 5.5-7 ju,. Sawada also revises the description of the 

 fungus as follows : " Conidiophores straight or more or less curved, 

 simple, hyaline, 16-27 ^ 3-5~4 H-l ^sci clavate-fusoid or fusoid,

 momi (erroneously spelled cinnamomii) on account of the lack of 

 the stroma which should be present in Glomerella.

1 Referring to Ideta's Handbook of Plant Diseases here quoted, the first 

 and second editions were published in 1901 and in 1902, respectively, under 

 the title Jitsuyo Shokubutsu Byorigaku (Practical discourse on plant diseases) ; 

 the third edition, issued in 1903, was greatly enlarged and largely rewritten, 

 and bears a new title, Nippon Shokubutsu Byorigaku ; it is called the third 

 edition in the German title page only. The fourth edition, which came out 

 under the same title, was issued originally in two parts, the first in 1909 (pp. 

 1-344) and the second in 191 1 (pp. 345-935. with appendices), and is really a 

 new work written under the critical supervision of Prof. K. Miyabe, who con- 

 tributed diagnoses of some of his new species published here for the first time. 

 Unaltered reprints of the fourth edition were issued in 1912 and in 1914, 

 sometimes called fifth and sixth editions.
