The representatives of the subsection are relatively small pigeons. Their mild meat usually has a typical fish or crab odor; it turns yellow or brown with age, if it is injured or when cut. It reacts green with iron sulfate and reddish to orange with aniline. The spore powder is cream-colored or ocher. The spores are thorny or warty and hardly reticulate. They differ from the other herring deafblings primarily in their location; the deafblings occur in the alpine zone above the tree line (+ 2300 m), where they live in a symbiotic relationship with silverwort , herbaceous willows or other dwarf willows.
