102 SALMON: SUPPLEMENTARY 
Distrib.—Japan : Tokyo, Botan. Garten. (Kusano no. 151, Oct. 
27, 1899). Prov. Szumo (Tanaka, Nov. 29, 1900). 
Hosts.—Rhus succedanea (fruit), R. vernicifera (leaves). 
Hennings (/. c.) gives the following diagnosis: ‘‘ amphigena; 
maculis fuscis effusis, mycelio arachnoides tenui, albido ; perithe- 
ciis gregariis subglobosis, atris 100-1104; appendiculis 12-16, 
simplicibus, subulatis interdum apice cirrhatis 100-150 x 6-10/4 
hyalinis ; ascis (2-3) ellipsoideis, vel subovoideis vix stipitatis, 8 
sporis 40-50 X 35-454; sporis ellipsoideis, utrinque rotundatis, 
1 guttulatis, hyalinis, laevibus 17-20 x 9-11. Die Art is 
mit U. flexuosa Peck und U. aceris DC. verwandt, durch die viel 
weniger askenreichen Perithecien u. s. w. verschieden.”’ 
Dr. Hennings sent me a specimen of his species (from Tokio), 
and on this I have remarked (‘‘ Erysiphaceae of Japan,” 68, P. 
440). ‘The specimen sent is too immature to enable me to give 
a full description of the plant. It appears, however, a distinct 
species, showing affinity with U. Sengokni Salm., but differing ™ 
the thicker walled appendages, slightly narrowed upwards to the 
closely coiled frequently helicoid apex.” 
I have since received from Professor Shotaro Hori an Uncinula 
which proved on examination to be the above species on the fruit 
of Rhus succedanea. The mycelium of the fungus covers the 
numerous depressions which occur in the fruit of the Rhus, and 
in the specimen sent bears only a few immature perithecia. The 
appendages are sometimes as few as seven in number; they a 
not swollen upwards, and terminate in a closely coiled oft 
helicoid apex ; towards the base they become refractive and thick- 
walled. 
U. seprata Salm.

Host.—Quercus glandulifera.

1899, no. 123 (in part); Mt. Tsukuba (T. Nishida, Nov. 2, 1900) 
‘“‘Hypophyllous : mycelium evanescent ; perithecia more e 
less scattered, large, rounded-lenticular, 160-210 yp in diametet 
cells of outer wall of perithecium distinct, small, 5-10 wide; ap" 
pendages crowded, very numerous, 100-170 or more in number .
