In China the FUJi-ling is made into edible cakes, which are Indian Bread, 

 frequently sold in the streets ; it is also reputed medicinal in a 

 variety of disorders. In America it has also been used as an 

 article of food, whence the name Indian Bread.

Tuberiform bodies of much smaller size, less regular shape, as 

 well as less ponderous than the preceding ; they are covered 

 with a thin, black, more or less shrivelled cuticle, which closely 

 invests a homogeneous, corky, yellowish-brown substance. The 

 microscopic structure of these quasi-tubers resembles that of 

 the Fuh-ling ; but the threads by which their substance is tra- 

 versed are more interwoven and more branched, and have not 

 the appearance of being the mycelium of a fungus. The same 

 irregularly shaped bodies as seen in Fuh-ling, are also present, 

 but their dimensions are smaller. In a few specimens, an 

 abundance of doubly prismatic crystals has been noticed. 

 " Treated with the same chemical tests as the Foo-ling" remarks 

 Mr. Berkeley, "it [the Choo-ling'] exhibits precisely the same 

 reaction. There is not the slightest trace of starch or cellulose, 

 and it is evident that the structure is not accordant with that of 

 any fungus or phaenogamous tuber." 



The Choo-ling is stated by Chinese authors to be parasitic 

 on a tree, beneath which it is picked up in spring and autumn, 

 many fanciful virtues not worth repeating are attributed to it.
