Pleurotus columbinus is a widespread, very tasty mushroom. It is actually parasitic, but can quickly switch to a saprobiontic lifestyle and is therefore easy to grow.

One of the main reasons for its success is its ability to digest all possible and impossible substrates. The peculiarity of being able to utilize various organic wastes makes it an indispensable source of food, especially in the third world.

You can grow Blue Oyster Mushrooms on banana stumps or on waste paper. They grow just as well on your old boiled jeans as they do on soaked bales of straw. Toilet paper rolls and compost piles are also not spurned.

The special ability of Pleurotus columbinus to train it to a particular substrate predestines it for biological decontamination. This type of organic remediation, known in English as mycoremediation, is increasingly being used around the world. Oyster mushrooms can be used to purify water, decontaminate heavily contaminated industrial subsoils, recycle used baby diapers, and much more.

Pleurotus columbinus grows on over-broiled straw pellets and other simple substrates, as well as on logs and stumps. There are no limits to your imagination in the choice of substrate, oyster mushrooms digest various raw materials, for which you may not even have to pay money. You will achieve the best breeding success with a sterile, well enriched substrate based on hardwood. You do not have to plan for long incubation times, the fungus usually fruits immediately after colonization of the substrate is complete. You can also achieve beautiful results in autumn/winter outdoors

Like all species of seitlings, the pigeon blue oyster mushroom likes good air exchange as well as good air movement (fanning) in the growing room.

Maintaining a CO² level below 1000 ppm in the room air and sufficient ventilation will ensure that the fruiting bodies develop without the stalk becoming long and thus tough. As classic side-fruiters, the fruiting bodies naturally develop in clusters without much stem content.

Although not mandatory, this genetic line also benefits from a 24-hour cold shock, which you can do just before opening the culture, called “birthing”.

Rather, avoid exposing the substrate to large areas for fruiting. By doing so, you will only encourage the formation of abortions, which will not develop into real fungi and will only cost the culture unnecessary strength. More yield you definitely do not have a larger surface area. In addition, the culture dries out much faster. You should avoid subsequent watering as much as possible during the first wave of harvest. Unless you want to invite bacteria, yeasts, molds, and insects to mushroom early on.

1. Dissolve the malt extract and agar in distilled water.
2.  Sterilize the solution by autoclaving at 121°C for 15-20 minutes.
3. Pour the sterilized media into petri dishes or other containers under sterile conditions.
4. The Yeast is optional, but you can add it to any recipe for nutritions, same for Peptone.

Pleurotus columbinus stems and the hat skin are very tough

Pleurotus columbinus grows in temperate biomes globally, especially in North America, Europe, and Asia. Recently, it's even been observed in South America.

mostly on dead coniferous wood, autumn, cultivated all year round
