Jew's ear - Auricularia auricula-judae - SPAWN FOR ORGANIC / BIO CULTIVATION ON Wood logs

Synonyms: Mu-Err, Wood Ear, Jelly Ear, Auricularia polytricha

This mushroom has an unusual, appealing texture. When eaten by itself, is not remarkably flavourful. Nevertheless, he is highly prized in Asia and is commonly used in soups as it takes on the taste of condiments very well. Jew's Ear is a gelatinous cup fungus, ear-shaped, generally purplish grayish brown to dingy brown and 2-15cm broad. Covered by a medulla of fine hairs. The surface is smooth, wrinkled towards the center.

This mushroom is sometimes called the chinese morel, although it is not related to morels

Jew's ear - Auricularia auricula-judae - Mushroom spawn for wood logs - small 
Certified for organic mushroom cultivation
(Organic control station: AT-BIO-301, Austria Bio Garantie)
1 autoclave bag approx. 1,8 kg - 3 liter
Suitable for inoculation of 16 to 20 linear meters of wood.


You receive ready colonized mushroom spawn made from organic raw material (wood, rye bran from organic farming) for inoculation of wood logs. Suitable woods hard-woods, especially oak, beech, birch, alder, elder or walnut.

For quantities of 10 or more logs inoculation with sawdust spawn is usually more efficient than working with dowels. Sawdust is a byproduct and more cost efficient and environmentaly sustainable than dowels that have to be produced. Because of this large quantities of spawn can be produced for a lower price. Sawdust spawn is suitable for the borehole inoculation method and the cutting inoculation method. Expected harvest yield is up to 10 % of the fresh woods weight divided on several flushes over 3 to 5 years.

For the borehole-method we recommend the usage of a mushroom drill, and an inoculation stick or a hand inoculator.
Larger quantities for commercial mushroom growing on request.
