Portobello Mushroom (Agaricus bisporus) Liquid Culture for Mushroom Cultivation on Grain or Agar

I ordered two spore syringes: one Portobello and one White Button. Unfortunately, the Portobello syringe was contaminated—the mycelium inside had a clumpy, slimy texture, clearly unsuitable for use. I’ve contacted the seller and am waiting for a refund for this syringe. On the positive side, the White Button syringe was perfect, with clean and healthy mycelium. Update: The refund process worked perfectly, and the seller took the time to address my concerns in a very professional and friendly manner. I am happy to update my review to 5 stars.

Arrived with a large amount of bacteria colonizing the syringe.

The liquid culture needle was not sterilized or the LC was bad. Unfortunately no spawn green and horribly infected..I'm done with edible mushrooms for now I want to try a really good "magic"mushroom grow. Idk I'll see if I wanna chance it again😞

I did get the white stuff but failed to get any mushrooms. Totally my fault because I didn't know what I was doing. Think my area was too cold. The item arrived quickly and did produce so I'm giving it 5 stars.

Worked well

Great spores! And came early. Not alot of options to finding these spores because they are such a common mushroom.

Unfortunately, on substrate and agar, huge contaminants. Unable to grow.

All I can say is yummy!

I purchased this liquid culture and then cloned it in a 1 liter bottle of culture. The entire bottle was filled with robust mycelium in a little over two weeks. This will be used to inoculate rye spawn and later the appropriate substrate. I highly recommend this vendor's products.
