Rhodofomes cajanderi is a widely distributed species of bracket fungus.

Commonly known as the rosy conk due to its rose-colored pore surface, it causes a disease called a brown pocket rot in various conifer species.

[1] It may be identified by its small-to-medium-sized, fleshy, tough fruit-body, with a downy or crust-like top.

[3] The top surface is a pink colour becoming to grey, brown, or black, with a clear margin.

[4] This species of polypore is morphologically similar to its relative, Rhodofomes roseus.
