NOTES ON THE ERYSIPHACEAE 103 
unequal in length (50~100 y# long) on the same perithecium, simple, 
smooth, 1-8- (usually about 5-) septate, amber-colored in the 
lower half, thin-walled throughout, about 5 » wide, apex often 
helicoid ; asci 6-12 (immature). ‘In habit, and in the large size of 
the perithecia, U. septata resembles ‘U. circinata Cooke & Peck, 
from which it is at once distinguished by the septate appendages ; 
from U. necator (Schwein.) Burr. and U. australiana McAlp.—the 
_ only species of the genus at present known which possess colored 
(septate) appendages—the large perithecia. with the crowded ap- 
pendages at once distinguish the present species. The absence of 
Spores in the ascus shows that the specimens examined are im- 
Mature ; but I have no hesitation in describing the plant in this 
Condition, as the presence of densely crowded septate appendages 
Shows it to be quite distinct from all other species at present 
known. The appendages when well developed cover more or less 
completely the upper half of the perithecium—just as is the case 
In U. circinata. Seen in the mass, the appendages are of a pale 
amber tint ; very probably they acquire towards the base, on ma- 
“use a deeper shade of brown, like those of U. ecator.” Salm.

U. septata was first found associated with ‘“ Sphaerotheca Ku- 
Sana P, Henn., of Shirai,” on a leaf of Quercus glandulifera, ina 
Specimen sent to me by Dr. Hennings. _I have since, through the 
Kindness of Dr. Hennings, been able to look over all the original 
material of “ S. Kusanoi,” but have not been able to find any 
Perithecia sufficiently ripe to contain spores ; I have observed, how- 
€ver, that the appendages are frequently 10-septate. Professor 
Shotaro Hori has sent me a specimen of S. /anestris (“‘ S. Kusa- 
700") or Quercus glandulifera from Mt. Tsukuba (coll. T. Nishida, 
jis, 2, 1900), and on the leaf a few immature perithecia of U. 
ala occur. Itis interesting to find that in this, its second known

otheca,
