Species Profile

Willow Pioppino (Agrocybe aegerita) grow in clusters.  They have tan caps and are very fragile.  The whole mushroom is edible.

Grows best on sterilized, nutrified sawdust.  Fruits in cooler temperatures, (13oC to 18oC)  with very high humidity.  They fruit within a couple of weeks of opening the bag.  Best if top fruited.


Our 1kg bags of grain spawn are grown using mycelium cultures in our lab. We use sterilized organic rye grain sourced from the Canadian prairies through Grainworks. We make your spawn to order.

We incubate your freshly made spawn between 2-4 weeks to ensure it is strong and healthy. We then ship via Canada Post or notify you for pickup.


Grain spawn must be mixed
with a bulk substrate to fruit mushrooms.

We recommend:

Experienced growers: Use this spawn to inoculate sterilized nutrified sawdust in filter bags. under sterile conditions. At a 10% inoculation rate, 1 bag of grain spawn (1kg) will inoculate about 10 to 12 14A Unicorn filter bags of sterilized substrate.


If you are new to growing, we highly recommend you take a workshop or buy a book on mushroom cultivation.

Care information

If you do not plan to use your spawn immediately, store it in a clean, undisturbed corner of your fridge for up to 6 weeks.
