Lung Oysters have quite a few intriguing abilities, including mycelia that can kill off and digest nematodes. It’s one of the few known carnivorous mushrooms, meaning it doesn’t thrive off of a saprophytic diet alone. ++
The Lung Oyster is a highly adaptive species that will produce clusters on several types of organic growing medium. That being said, substrate materials that have continually proven to produce the largest yields are hardwood sawdusts, cereal straws (rice, wheat), corn stalks, sugar cane bagasse, coffee grounds/waste, cotton waste, and a number of other waste by-products from forest materials or agriculture. +++ Pleurotus pulmonaris yields can be boosted, just as many others, by adding additional nitrogenous supplements, however, this advantage is often offset by an increased opportunity for contamination to set in.
Just as many other oyster mushroom varieties, the Lung Oyster often displays high sensitivity to CO2 levels in the air. Without proper monitoring of CO2 levels (ideally kept at less than 1,000 ppm), obvious fruiting body malformation occur. +++
