Jelly Ear

Description:

The fruit body of A. auricula-judae is normally 3 to 8 centimetres (1.2 to 3.1 in) across, but can be as much as 12 centimetres (4.7 in). It is distinctively shaped, typically being reminiscent of a floppy ear, though the fruit bodies can also be cup-shaped. It is normally attached to the substrate by the back surface of the cup, though there can also be a rudimentary stem. The species has a tough, gelatinous, elastic texture when fresh, but it dries hard and brittle. The outer surface is a bright reddish-tan-brown with a purplish hint, often covered in tiny, downy hairs of a grey color. It can be smooth, as is typical of younger specimens, or undulating with folds and wrinkles. The color becomes darker with age.

Habitat:

Grows upon the wood of deciduous trees and shrubs.

Notes:

Auricularia auricula-judae has been used as a medicinal mushroom by many herbalists. It was used as a poultice to treat inflammations of the eye, as well as a palliative for throat problems. The 16th-century herbalist John Gerard, writing in 1597, recommended A. auricula-judae for a very specific use; other fungi were used more generally. He recommends the preparation of a liquid extract by boiling the fruit bodies in milk, or else leaving them steeped in beer, which would then be sipped slowly in order to cure a sore throat.
