Lentinellus cochleatus, commonly known as the aniseed cockleshell, is a wood-inhabiting fungus.
The tan cap grows up to wide, often with a darker margin and depressed in the center. It has a mild aniseed odor and flavor.
Similar species include Lentinellus micheneri and Crepidotus nyssicola.
It is widespready in Britain and the rest of Europe, on broadleaf wood, from July to December.
Some consider all members of the genus inedible due to their bitterness, but one guide suggests that it is good cooked or dried as a seasoning.
