Organic Jew's Ear - Auricularia auricula judae - Sawdust-Spawn
Synonyms: Mu-Err, Wood ear, Jelly ear
This mushroom has a firm texture and little inherent flavor, making it particularly receptive to the aroma of spices. In Asia, in is traditionally used in sauces and soups because it releases substances while cooking that thicken the soup or sauce, making it creamier. The Judas' ear mushroom has a gelatinous cap shaped like an ear. Generally, the cap, which can be 2 - 15cm wide, ranges in color from purple-grey-brown to dirty brown. It is surrounded by a framework of fine hairs. The surface is smooth and folded towards the center. Sometimes, this mushroom is also marketed as the Chinese morel; However, the Judas' ear is not related to morels.
Sawdust spawn is always made fresh on demand. Production time: 3 - 6 weeks.

Suitable cultivation methods:
wood logs, spawn bags in indoor greenhouses
Suitable substrate: hardwood
Suitable woods: birch, beech, alder, elderflower, elm and walnut
Outdoors: this strain produces fruiting bodies in late summer up to early winter
You receive fully colonised sawdust spawn based on organic raw materials (wood, rye bran from organic cultivation) in bags specifically suitable for sterilisation.
Information for cultivation on straw and substrate:
1 autoclave bag with app. 3 litres of mushroom spawn is suitable for inoculating 1 straw bale or 5 - 15 substrate bags
1 autoclave bag with app. 6 litres of mushroom spawn is suitable for inoculating 2 straw bales or 10 - 30 substrate bags.
Information for cultivation on wood:
When using our equipment
(inoculation stick or hand inoculator) the sawdust spawn bags are suitable for:
1 autoclave bag with app. 3 litres of mushroom spawn is suitable for inoculating 12 - 15 linear metres of wood
1 autoclave bag with app. 6 litres of mushroom spawn is suitable for inoculating 25 - 30 linear metres of wood
For quantities of 10 logs or more, inoculating with sawdust spawn ins usually more efficient than working with spawn dowels. The raw materials sawdust and wood chips are by-products and therefore more cost effective and sustainable than specially manufactured wooden dowels. As a result, sawdust spawn can also be produced cost-effectively in large quantities. Sawdust spawn is suitable for the drilling method and the cut inoculation method.
The expected yield is up to 10% of the fresh wood weight, divided into several harvest waves over a period of 3 - 5 years
When utilising the drilling methode we recommend using a mushroom dirll and an inoculation stick or hand inoculator.
Suitable for beginners.
Large quantities for commercial mushroom cultivation available upon request.
