Red Chanterelle Agar Plate Culture FAQs
What is a Red Chanterelle mushroom agar culture?
A Red Chanterelle agar plate culture contains living mycelium from the Red Chanterelle mushroom, Cantharellus cinnabarinus, growing across a nutrient-rich agar medium. It can be used to expand the culture onto fresh agar or to inoculate sterilised grain and hardwood-based substrate.
Red Chanterelles are mycorrhizal mushrooms. Unlike common saprophytic species such as oyster mushrooms, they form a beneficial relationship with the living roots of compatible host trees. They are therefore more difficult to establish and are not normally grown in standard indoor fruiting blocks.
How do I use a Red Chanterelle agar plate?
Work in the cleanest environment possible, ideally in front of a laminar flow hood or inside a still-air box.
Using a sterile scalpel:
Cut a small wedge from the healthy outer edge of the mycelium.
Transfer the agar wedge into sterilised grain, sterilised hardwood substrate or onto a fresh agar plate.
Seal the receiving container immediately.
Allow the mycelium to establish before using the colonised material around the active root zones of a suitable host tree.
Additional transfers can be made using our Light Malt Extract Agar Plates.
Can I inoculate sterilised grain directly from the agar plate?
Yes. Small wedges of colonised Red Chanterelle agar can be transferred into a pre-sterilised grain bag.
Adding several small agar wedges at different points inside the bag can help the mycelium establish more evenly. Always use sterile tools and minimise the amount of time the bag remains open.
Once the grain is well colonised, it can be planted into the soil around the active root zones of suitable host trees.
Can Red Chanterelle be grown on hardwood substrate?
Yes. Red Chanterelle mycelium can be introduced into sterilised hardwood sawdust or a supplemented hardwood substrate as an intermediate growing medium.
You can use a Sterilised Hardwood Mushroom Grow Bag or our 2 kg Hardwood and Wheat Bran Bulk Substrate.
After the hardwood material has become colonised, it should be planted around the active feeder-root zones of a suitable host tree. The aim is to help the chanterelle mycelium contact living roots and establish a mycorrhizal relationship.
Which trees can host Red Chanterelle mushrooms?
Red Chanterelles are associated with compatible woodland trees, particularly suitable deciduous species. Potential hosts may include:
Oak
Beech
Birch
Other compatible mature woodland trees
Choose a healthy, established tree in an area with suitable soil, moisture and woodland-like conditions. Results can vary because successful establishment depends on the mycelium forming a compatible relationship with the living roots.
Where should I plant colonised Red Chanterelle material?
Plant colonised grain or hardwood substrate around the active root zone of a suitable host tree, rather than directly against the trunk.
The most suitable area is generally beneath the outer canopy where fine feeder roots are active. Create several small planting holes, add the colonised material and cover it gently with the original soil and leaf litter.
Keep the area naturally moist but not waterlogged. Avoid heavy digging or disturbing the roots.
How long does Red Chanterelle mycelium take to colonise grain or substrate?
Red Chanterelle mycelium is generally much slower than oyster mushroom mycelium. Colonisation may take approximately four to eight weeks or longer, depending on:
The amount of agar transferred
The grain or substrate used
Incubation temperature
Moisture levels
Sterile technique
The overall vitality of the culture
Do not expect the same rapid, dense growth commonly seen with oyster mushroom species.
What temperature is best for Red Chanterelle mycelium?
Red Chanterelle mycelium generally performs well at moderate indoor temperatures of approximately 18°C to 23°C during initial agar, grain or substrate colonisation.
Keep the culture away from direct sunlight, radiators and large temperature fluctuations.
How should I store my Red Chanterelle agar culture?
Store the sealed Red Chanterelle agar plate in a refrigerator at approximately 2°C to 8°C until you are ready to use it.
Do not freeze the culture. Keep the plate sealed and protected from repeated temperature changes. For the strongest growth, use the culture as soon as reasonably possible after delivery.
How long will the Red Chanterelle agar culture remain viable?
A properly sealed and refrigerated Red Chanterelle agar plate can remain viable for several months. However, cultures are best used while they are fresh and actively growing.
Every Artisan Mushrooms agar culture is made fresh to order to help provide maximum freshness, vitality and healthy mycelial growth.
Please allow up to two weeks before dispatch while your culture is prepared, colonised and checked.
What does healthy Red Chanterelle mycelium look like on agar?
Healthy Red Chanterelle mycelium is normally white to pale cream and may appear:
Fine and wispy
Slow growing
Uneven around the original transfer point
Feathery around the outer growing edge
Less dense than oyster mushroom mycelium
Appearance can vary depending on the age of the culture, agar recipe and incubation conditions.
What are the signs of contamination on an agar plate?
Possible signs of contamination include:
Green, black, pink or unusual brightly coloured growth
Wet or greasy-looking patches
Unusual bacterial slime
Strong yellow or brown discolouration
Growth that appears separate from the intended mycelium
Do not open or use a plate that appears contaminated. Keep it sealed and contact Artisan Mushrooms with clear photographs.
Can I make more agar plates from this culture?
Yes. A small piece of healthy Red Chanterelle mycelium can be transferred onto a fresh agar plate to expand and preserve the culture.
Use a sterile scalpel and transfer a small wedge from the clean, actively growing outer edge of the colony. Our Light Malt Extract Agar Plates are suitable for making additional culture transfers.
Is Red Chanterelle agar suitable for beginners?
Red Chanterelle is better suited to patient growers who understand that mycorrhizal mushrooms are more difficult to establish than common gourmet species.
Beginners can still work with the culture, but successful outdoor establishment is not guaranteed. Sterile technique, a compatible host tree, suitable soil conditions and long-term patience are essential.
How long does Red Chanterelle take to fruit?
Red Chanterelles may take several years to establish and produce mushrooms outdoors, even when suitable host trees and soil conditions are present.
Fruiting cannot be guaranteed because success depends on the mycelium forming a compatible mycorrhizal relationship with living tree roots and adapting to the local environment.
Can Red Chanterelle be grown indoors like oyster mushrooms?
No. Red Chanterelles are not normally grown as conventional indoor block-fruiting mushrooms. Their natural life cycle depends on a relationship with living host-tree roots.
The agar culture is best used to produce colonised grain or hardwood material that can then be introduced into suitable outdoor root zones.
