Organic Zhu ling - Polyporus umbellatus - SPAWN FOR ORGANIC / BIO CULTIVATION ON Wood logs

Syn.: Umbrella polypore, Zhu Ling, Chorei-maitake, Tsuchi-maitake, Chinese sclerotium

The Polyporus umbellatus creates bushy fruiting bodies, composed of numerous round single standing fruiting hats. These can reach diameters of 20 to 40, sometimes 50 cm and weigh several kilograms. The individual stems converge in a common stalk. The stalk arises from a black-brown sclerotium, which is located close to the soil surface. The individual hats are coloured pale yellow to grey-brown and have a width of 1 - 4 cm. They have a rough surface and are mostly immersed in the middle. The edge is wavy bent and relatively thin. On the bottom of the hats is a whitish porous layer that can run far down the stem. The pores are round and the tubes are one to two centimeters long. The flesh is also whitish, fibrous and brittle. It smells like flour, pleasant when young; aged, however, it has an unpleasant odor.

Organic Zhu ling - Polyporus umbellatus - Mushroom spawn for wood logs
Certified for organic mushroom cultivation according to Regulation EC 834/2007 and 889/2008
( Organic control station: AT-BIO-701, Biko Tyrol)
1 autoclave bag approx. 1.8 kg - 3 liter
Suitable for inoculation of 12 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 are: maple, birch,  beech or oak.
This strain is fruiting in late summer to early fall.

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.
