>>2789943Are you talking about mycelium? All mushroom mycelium looks pretty much the same. Some are more tomentose and some are more rhizomorphic, but they're all a white mass. Oysters are wood decay mushrooms. They are a white rot decayer, meaning they consume the lignin in wood. Their primary home will be in hardwood logs. They don't survive well in soil. And they only live for a couple flushes on those commercial blocks before they die.
If you have an actual log that you found in the woods and brought home, it'll fruit for around 1 year per inch of thickness, as long as you provide it the right amount of water and a proper micro climate for the mushrooms to fruit.
There are many mushrooms that grow in potting soil. Some organic soil companies add mushroom mycelium and/or spores to the mix. The mycelium helps break down humic material in the soil making it available for the plants to absorb. I seriously doubt any mycelium you're seeing in the soil is oyster. Far more likely to be coprinus/coprinopsis or a mycena variety. But there's no way to know unless you actually see mushrooms. Anyone that's grown potted plants for any significant amount of time has seen the occasional mushroom pop up. It's usually a sign of healthy soil.
