King Trumpet
King Trumpet (also called King Oyster or Eryngii) is the premier thick-stemmed mushroom in commercial cultivation. Its massive, solid stems and small caps create a product that's instantly recognizable and highly sought after by chefs, grocery buyers, and health-conscious consumers. The dense, scallop-like texture and exceptional shelf life (up to 14 days refrigerated) make King Trumpet ideal for retail distribution. However, this variety demands tighter environmental control — cooler temperatures, top-fruiting technique, and more precise humidity management. It rewards experienced growers with a premium product that commands top dollar.
Cultivation Tips for King Trumpet
Top fruit only — cut the top of the bag and fold down. King Trumpet does not fruit well from side cuts.
Temperature control is critical. Stay between 50–60°F for the thickest, most marketable stems.
Low light and moderate CO2 (800–1200 ppm) during development promote thick stem growth. Too much fresh air creates large caps and thin stems.
Harvest when stems are firm and caps are still small relative to stem diameter. This is the most marketable form.

King Trumpet is a culinary powerhouse — the thick stems can be sliced into scallop-like medallions and seared to golden perfection. The texture is remarkably meat-like, making it the go-to mushroom for plant-based steaks and fine dining preparations. It absorbs marinades beautifully.
