Among the specimens of Erysiphaceae sent to me by Professor 
Kingo Miyabe, there occurs a Sphaerotheca on Veronica which 
must be referred to the S. humuli type. This occurrence is specially 
interesting on account of the fact that up to the present only the 
var. fuliginea of S. humuli has been known on species of Veronica. 
In Europe, Siberia and Asia, and North America S. humult 
Fuliginea occurs on Veronica Virginica (Rab.-Wint. Fung. Eur. 
3657, from Missouri, U.S. A., sud S. Castagnet Lév.); on ¥, 
Spicata (Roumeg. Fung. gall. exsicc. 2741, from Rouen, France, 
sub S. Castagnei Lév.): on V. longifolia (Syd. Myc. March. 1239, 
from Berlin, Germany, sud S. Castagnei Lév.), (Rab. Fung. Eur. 
2026, from Saxony, sub Erysiphe Castagnei forma veronicarum), 
(de Thiim. Myc. univ. 1839, from Minnussinsk, Siberia, occid., 
oS: Castagnet Lév.). In all the above-cited examples the 
fungus is typical S. humuli Suliginea, with perithecia measuring 
©M 60~70 yp in diameter, and the cells of the outer perithecial 
ie: averaging 25 ft wide. The Japanese plant, of which two 
: &xamples have been sent—‘on the skins of Veronica Virginica
