The Crimson Classic

​Add a splash of rare color to your lab with the Colombian Rust. This variety is a true “genetic gem” originally isolated from a classic Colombian strain. It is famous worldwide for one very specific, stunning trait: it produces rust-colored spores. While almost every other variety in the world has dark purple or black spores, this one stands alone with its unique, reddish-brown “rust” hue.

​What Makes Colombian Rust Special:

​Unique Spore Color Under the microscope, the Colombian Rust is a total game-changer. The vibrant, rust-colored spores provide a completely different visual experience for researchers and taxonomists. It’s a “must-have” for any serious spore library.

​Rock-Solid Reliability Despite its exotic spore color, this strain is a sturdy, dependable Cubensis. It is very easy to work with and isn’t “picky” about lab conditions, making it a great choice for researchers of all skill levels.

​Aggressive Growth This culture is known for its vigor. It produces strong, healthy white mycelium that colonizes with purpose. It is a reliable performer that doesn’t leave you guessing.

​Classic Colombian Heritage It carries the robust traits of its South American ancestors—thick stems and beautiful, cream-to-caramel caps that contrast perfectly with the unique spores they drop.

​If you’re looking for a strain that combines “easy-to-study” reliability with a rare, colorful twist, the Colombian Rust from Marvelous Mike’s is the perfect addition to your Forge.
