MATERIA MEDICA OF THE ANCIENT CHINESE. 419 
5.—The ™ | hei (black) chi, called YF | haan 
(dark) chi in the Pen king—it is also called $$ | su — 
chi—grows on the Ch‘ang shan mountain [in Chi li, 
App. 8]. Taste saltish. Non-poisonous. 
6.—The 3& | tse‘ (purple) cht, which is called 
As | mu (wood) chi in the Pen king, grows on the 
Kao hia shan [mountain, unknown to Tao Hunc- 
KING]. Taste sweet. Non-poisonous. 
It is believed that the felicitous plant chi, or plant of 
immortality of the ancient Chinese, is the 9 3 ling chi 
(divine ch?), a branched Agaricus which is now sold in Chinese 
drug-shops [see Bot. sin., Il, 41]. In the P. [XXVIIL, 
35] ling chi is given as a synonym of #4 FH shi rh (mush- 
room which grows on stones). The name ling chi appears 
first in the Ling yuan fang [11th cent.] 
In the Cust. Med. the drug ling chi is twice mentioned, 
[p. 206 (324)] as imported to Ning po from Han kow and 
[p. 808 (502)] as imported to Amoy. It is identified there 
with bird’s excrement.

267.— Ff mu rh. P., XXVIII, 26. 7., LU. 
Pen king :—Mu rh (woody ears,—mushrooms produced 
on trees), Taste sweet. Nature uniform. Slightly poisonous. 
Pie lu:—There are five kinds of mw rh, which grow in 
Kien wei [in Sz ch‘uan, App. 140]. They are gathered 
in the rainy season, in the 6th month, and dried in the sun. 
T‘so Hune-xing :—The Pie Iu does not say on what 
trees these mushrooms grow. The 3 FH sang (mulberry 
tree) rh grows on old mulberry trees and is of a green, 
yellow, red or white colour. The mushrooms called mu rh 
are gathered by the people and pickled for food, but not 
used in medicine.
