Description
Black Poplar Mushroom (Cyclocybe aegerita) Grain Master
For sale is a 1-quart jar of Black Poplar Mushroom Spawn. This is a generation 1 grain master mushroom spawn jar used for expansion of isolate mycelium, optimized for spawn run times and bio efficiency.
Out Grow has isolated this Black Poplar culture, also sold as Pioppino, for its reliable clustered fruiting on sterilized hardwood and its deep brown cap colour.
What a G1 Grain Master Is
A grain master is a jar of fully colonized grain made to be transferred, not consumed. Generation 1 means the mycelium in this jar came directly from one of our agar plates rather than from another bag of grain, so it sits one step from the culture library instead of three or four. That matters because every transfer is another opportunity for contamination to ride along, and because a G1 jar still has the full expansion runway ahead of it. One quart can seed several more quarts of sterile grain, and those can seed your bulk substrate.
How to Use This Jar
Rest, break, recover, transfer. Black Poplar colonizes grain steadily and expands cleanly. Spawn to sterilized supplemented hardwood sawdust or Master's Mix.
Black Poplar Growing Conditions
Black Poplar colonizes grain in 14 to 28 days at 70 to 77F and fruits cool, from 50 to 65F. It is a reliable indoor fruiter on sterilized hardwood provided you can hold a cool fruiting room, and it simply will not perform at oyster temperatures. Clusters come as dark brown caps on long pale stems, and unlike most cultivated species the stems are worth eating. It is one of the better flavoured mushrooms in this collection and considerably more interesting on a plate than another oyster.
| Spawn run | 70 to 77F |
|---|---|
| Grain colonization | 14 to 28 days |
| Fruiting temperature | 50 to 65F |
| Substrates | Supplemented hardwood sawdust, Master's Mix, straw |
| Difficulty | Intermediate |
| Season | Cool season |
| Also known as | Pioppino |
Storage and Shelf Life
Refrigerate at 35 to 40F. Warm to room temperature for a day before transferring. Do not freeze.
In the Kitchen
Firm stems and a genuinely savoury, almost meaty cap. It holds up to long cooking better than most and is the classic mushroom for Italian braises and ragu.
Guarantee and Live Shipping
Every jar is inspected before it leaves our lab and guaranteed to arrive alive and contamination free. If it does not, photograph the jar sealed and unopened and contact us within 48 hours of delivery for a replacement or refund. Live spawn is temperature sensitive, so we hold shipments during extreme heat and cold rather than sending something that will not survive the trip.
