Clitocybe odora

Species of fungus

Clitocybe odora, commonly known as the blue green anise mushroom, This odor can give away the mushroom's presence before it is observed by eye.

First described by the French mycologist Jean Baptiste Francois Pierre Bulliard (1742–1793). The specific epithet odora is from the Latin meaning "perfumed".

Young specimens have a light blue texture on the cap which fades to grey in age. The gills and stem are white with no ring. Full grown specimens have blue green, flowery, cup shaped caps; the gills are creamy white, or reflect the blue green color of the cap. The cap's surface feels rough. The stem is thick, is attached to the gills with no rings, and is textured, with a pale yellow colour. The younger ones have a bell shaped cap with a light blue or icy blue colour. The gills and stem are white, or bluish green. It has a strong scent and taste of aniseed, hence its name. There is a white variety (Clitocybe odora var. alba Lange) that has the same strong odour.

Found in both deciduous, and coniferous woods, it is widespread in the temperate zones, occurring in Asia, Europe, and North America. On the East Coast of North America it favours oak woodland, but it is often abundant in the coniferous forests of the Pacific Northwest.

The caps can be dried, and used as a condiment, or used fresh for flavouring. Mushroom hunters should be sure to pick mature ones, mainly because the younger ones can be confused with several similar poisonous ones that grow along with this mushroom. Every part of the mushroom should be examined before collecting for the table. Also, the stem and the cut cap should be checked to see if there are any fly larvae. Some guides recommend avoiding eating the species.
