Pleurotus pulmonarius easy cultivares on pasteurized straw, sterile upgraded wood substrates and logs. Unlike oyster mushrooms, lung mushroom also digests coniferous substrate if it has been previously treated in a suitable manner. Decorticated coniferous small animal litter is also suitable without pretreatment. For further instructions, see my brown lung mushroom or my oyster mushroom.
Sufficient fresh air and ventilation are essential for a good result. Timely fruiting directly after incubation prevents the formation of too dense surface mycelium, on which primordia often no longer form.
Pleurotus pulmonarius also tolerates permanently high temperatures up to 28°C and then forms very large fruiting bodies at record speed, which, however, do not achieve the firmness, storability and taste as mushrooms, which you produce under cooler conditions.
Unlike plants or some bacteria and protists, fungi are unable to manufacture their own food from abiotic sources like the sun. So, in their quest for nutrients, many fungi, including Pleurotus, adopt their nutrition from other decaying organisms.
They go about this by excreting digestive enzymes through the tips of root-like extensions called hyphae. The enzymes break down their food leaving a space filled with nutrients that the hyphae can continue growing into, absorbing, and digesting again as it feeds. The hyphae branch and grow into a thicker mass called a mycelium, which maximizes the surface area through which feeding can take place.
Oyster Mushrooms has been successfully grown from a variety of substrates including sawdust, newspaper shavings, and even rolls of toilet paper. If you’re interested in growing them yourself, kits are available online. I’m not about to endorse any of them myself, but you can google it if interested. The oyster mushroom isn’t a picky fungi in nature either. Pleurotus ostreatus will grow on a variety of woods
