Brown Shimeji (Hypsizygus tessellatus — Buna-shimeji)

Brown Shimeji is a refined and extremely popular gourmet mushroom known for its firm texture, deep umami flavour, and beautiful patterned brown caps. A staple in Japanese and Korean cuisine, this species produces dense, uniform clusters that are highly rewarding for home and commercial growers alike. Our cultures are produced fresh in our sterile UK lab and delivered in the format that suits your grow: liquid culture, agar plate, agar slant or ready-to-fruit grow kit.

🔥 Why Grow Brown Shimeji?

• Attractive clusters with distinctive mottled brown caps

• Rich, nutty, umami-heavy flavour — superior to white varieties

• Excellent texture: firm, crunchy and holds shape in cooking

• Reliable coloniser on grain and supplemented hardwood

• Highly resistant to contamination compared to many gourmet species

🧪 Produced in Our UK Sterile Lab
