About the black mushrooms:

mu er means tree mushrooms. There are at least three species, the two 
most common being Auricularia polytricha and Hirneola auricula judae. A. 
polytricha is much larger and is referred to be the Chinese as Woolly 
wood ear (mao mu er). Fresh mushrooms can be as large as 25 cm. They 
typically have a haired side. 
The small ones (less than 2 cm in a dried stat) are probably Hirneola 
auricula judae
