Suborder Auricularine.*:. — Family Auriculariace^. — The 

 fungi of this family are saprophytes, or wood-inhabiting parasites. The 

 basidia are borne directly on the mycelium, or in variously formed fruit 

 bodies in which the basidia form a layer. The basidia are transversely 

 divided into four cells. Auricularia includes about forty species of 

 which the best known \% Auricularia (Hirneola) Auricula J udeB, the Jew's 

 ear fungus, which develops its fruit body on rotten wood. When wet it 

 is gelatinous; when dry, it appears as a dry crust. It is a rather gelatin- 

 ous, flabby-looking, thin expanded cup or saucer-shaped fungus of 

 a brownish color when expanded smooth inside, veined and plaited so 

 as to have the resemblance to a human ear. It grows on a variety of 

 trees: elm, maple, hickory, balsam, spruce and alder and up to 1900, 

 it had been collected in Ohio, Maryland, Indiana, New Jersey, Pennsyl- 

 vania and West Virginia. Outside it is velvety and grayish-olive.
