The Prince Agar Plate (Agaricus augustus)

Agaricus augustus, famously called The Prince, is a rare and highly regarded gourmet mushroom known for its impressive size, nutty aroma, and rich flavour. Found naturally on forest edges and composted soils in cooler climates, this species can be cultivated under the right conditions—making it a unique addition to Sri Lanka’s specialty mushroom offerings.

This research-grade culture is grown on nutrient-rich agar and produced under sterile lab conditions. Each plate contains vigorous, contaminant-free mycelium, ready for grain spawn expansion or long-term culture storage. It’s a perfect choice for farms targeting high-end markets or experimenting with non-commercialized species.
