Description
Please watch our video to learn more about P1, P2 and P3 cultures.
Professional Range
P1 cultures, also known as master liquid Cultures, are the most vigorous cultures available on the market.
P2 Cultures are made from P1 cultures by expanding them 10 folds, so 10 ml to 100 ml.
Commercial Range
P3 Cultures are made from P2 cultures by expanding them 10-fold, so 10 ml to 100 ml.
Orientation-Top fruiting. Ivory Shimeji is a wood-loving mushroom. Grow on Sawdust 80% and bran 20% or a master mix(Mix of Sawdust and Soy hulls) substrate. The substrate needs to be Sterelised.
Mushroom farms grow them in 3-4 Kg blocks in a grow bag.
Ivory shimeji mushrooms have a mild, slightly nutty flavour and a firm, crunchy texture. They are often described as savoury and umami-rich, with subtle buttery and sweet notes. They are a bit milder in taste than brown shimeji, and they are best enjoyed cooked in dishes like soups and stir-fries.
Ivory Shimeji (Hypsizygus tessulatus) Also known as Hon Mushroom and White Beech. Gourmet Fruiting temp: 12°-18°C
Store Ivory Shimeji in the fridge at 2°C.
Incubate at 22°C. Maintain humidity at 90-100% for pin formation and drop by 5-10% during fruiting. If the fruits start to turn yellow, decrease the temperature. If the fruits start to turn leggy, increase the airflow.
This strain is used for gourmet purposes.
The liquid culture can be used in various cultivation techniques. You may introduce the liquid culture into sterilized grain jars/bags, agar Petri dishes, or even another nutrient Sterile jar to expand into the more liquid culture.
This mushroom liquid culture is made with the best strain we can find. It is checked every six months for its vigour and ability to fruit on a commercial scale. Each jar is tested before it is sent out. We give a 100% guarantee on our culture.
We offer High-Quality Disposable Gloves and Masks, essential for maintaining sterile conditions in your mycology projects. We also recommend you buy Biodegradable MEA agar cups for those testing liquid cultures or spore syringes before inoculating their bags. Do you need a sterile workspace? Have a look at our Still Air box (SAB).

Importing Mushroom Cultures into New Zealand
If you’re in New Zealand and want to bring in mushroom cultures from Rootlab, whether that’s liquid culture, agar plates, or spawn, you’ll need an MPI import permit first. Here’s exactly how it works.
Step 1: Check the species is approved
MPI only allows import of the following species (current as of June 2026):
**A to C**
– Agaricus bisporus (Portobello/White button)
– Agaricus bitorquis
– Auricularia cornea
– Boletus edulis
– Chlorophyllum rhacodes (Macrolepiota rachodes)
– Coprinus comatus (Shaggy mane)
**D to O**
– Flammulina velutipes (Enoki/Golden Enoki)
– Flammulina filiformis
– Lactarius deliciosus
– Lentinula edodes (Shiitake)
– Marasmius oreades
– Morchella esculenta
– Morchella importuna (Morel)
**P to Z**
– Pleurotus djamor (Pink Oyster)
– Pleurotus ostreatus (All various types of oyster)
– Pleurotus pulmonarius (Phoenix oyster)
– Stropharia rugosoannulata (Wine cap/Golden wine cap)
– Trametes versicolor (Turkey Tail)
– Volvariella volvacea (Paddy Straw)
These can be imported as mother culture (pure culture on agar or in sterile broth), spawn (pure culture on a sterile plant-based carrier), or substrate (sterile plant-based product inoculated with spawn).
Rootlab website shows what we currently stocks, the full MPI list above is what’s allowed, not necessarily what we carry or make available for sale.
Requirements mentioned here:

Step 2: Send us your details
Email us with:
– Your full name
– Company name (If applicable)
– Full delivery address
– Mobile number
– The cultures you’d like, picked from the species we stock
Our email: info@rootlab.co.nz
Step 3: We send you a Manufacturer’s Declaration
Once we have your details, we’ll send through a Manufacturer’s Declaration. You’ll need this when you apply for your import permit.
Step 4: Apply for your permit and pay the fees
Once your permit is approved, you can place your order at www.rootlab.co.nz. We take care of the export paperwork and freight from there.
The only thing you need to do is apply for the permit, all the details you need will be in our Manufacturing Declaration, then choose which products you want to import. Everything listed on our website is already permitted, so you won’t find anything on there that isn’t allowed.
Tip: a colonised agar plate takes 3 to 4 weeks to prepare, which lines up with permit processing times. So you can place your order as soon as you’ve applied for the permit, no need to wait for approval first. If your permit doesn’t come through, we’ll give you a full refund.
