Suillus tridentinus, the orange larch bolete, is an uncommon, edible mushroom in the genus Suillus, found mainly at higher altitudes beneath larches on chalk.

The bolete is considered endangered in the Czech Republic.

[1] The cap is convex, orange to rusty red, slimy and often covered with dark brown scales.

The stipe is rusty orange like the cap, with a hint of a slimy, yellowish-white ring that soon disappears.

An extract of Suillus tridentinus exhibits inhibitory activity on thrombin.
