Pleurotus pulmonarius
Pleurotus pulmonarius is more commonly known as the “Italian Oyster,” “Spring Oyster,” or simply “Brown Oyster.” This close cousin of the grey oyster has a firmer, more developed stem with a spongy or alveolate tendency, prefers milder conditions, and grows in beautiful clusters or sometimes as very large fruiting bodies from the southern Alps to the foothills of the Himalayas.
History
The brown oyster grows naturally in North America and Europe. Like all its Pleurotus cousins, it feeds on dead or diseased hardwood, but it is also found in coniferous forests above 1000 meters altitude. It seems able to adapt to the acidity of some conifer woods and to the antifungal agents produced by these trees.
In indoor cultivation, the mycelium of the Italian oyster is among the fastest to colonize its substrate, and its adaptability is truly astonishing. It has become THE mushroom to cultivate worldwide—perfect for beginners because its aggressiveness leaves little room for contamination, and for growers in tropical and subtropical regions like India or Africa, where it has become an important source of protein and income for local populations.
