Shipping policy

Delivery delay :

We work with living products (mycelia) which have a limited lifespan. We try to send the mycelia as soon as they are ready, at maximum vigor. This is why most of our products are made to order, which can take 2-3 weeks. This is the time it takes for the mycelium to develop.

For the most commonly requested products we generally have stock and can send it more quickly (oyster mushrooms for example). For other non-living products (bags, dry substrates for example), we generally send the products within 2-3 working days.

Delivery takes 1 to 5 working days depending on the carrier and destination.

We fully reflect carrier prices, and we make no margins on transportation.

Confirmation: You will receive an email confirming receipt of your order. If this is not the case, first check your spam folder, otherwise contact us about this. You will receive a second email when your order is shipped, with a tracking number. With Mondial Relay, you also receive an email and/or text message confirming the arrival of the package at the drop-off point.

Carriers: Shipments are made via La Poste, Colissimo or Mondial Relay. Depending on the destinations and the type of shipment, the customer chooses their carrier. Shipping costs depend on the weight of the products and the destination. The price is indicated after indicating your address, before payment.

If you do not receive confirmation or notification about shipping from us, please check your spam folder first.

Risks and responsibilities: Delivery is included from the moment the packages are picked up by the carrier.

Depending on the destinations and times of year, temperatures can be detrimental to the proper preservation of the mycelium during transport (>25°).

Delivery is the responsibility of the customer. Odyssey mushrooms is not responsible for any possible deterioration of products during transport, due to temperature, late delivery, customs blockage or storage conditions at the collection point for example (non-exhaustive list).

Odyssey mushrooms is not responsible if the package could not be delivered due to a wrong address indicated by the customer, its absence during delivery, or a delay exceeded at the relay point for example.

We have the option of sending refrigerated transport if necessary (shipping costs are higher).

Returns: Concerning live products (mycelia), there are no returns possible. Transport conditions cannot be guaranteed (temperature, shaking, etc.). Upon return, the mycelia support a second transport and would not support a third transport, they are therefore considered lost and to be replaced.


The importer takes responsibility for the various problems that may arise during transport (in particular customs blockages).

We also provide the packing slip and the order invoice, which are necessary for customs clearance.

For shipments outside the EU we favor liquid cultures (in syringes) which are more resistant to transport.
