Clitocybe odora, commonly known as the blue green anise mushroom, or aniseed toadstool, is a blue-green mushroom that smells strongly like anise. It grows near deciduous and coniferous trees, in small groups alongside tree roots. This mushroom is edible but may resemble poisonous species.

Taxonomy

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

Description

Young specimens have a light blue texture on the cap which fades to grey in age; it measures 3–8 centimetres (1–3 in) wide. The gills run down the stem; both white with no ring. It grows up to 6 cm (2+1⁄2 in) tall.

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. The odor is due to the presence of p-anisaldehyde and a small amount of benzaldehyde.

There is a white variety (Clitocybe odora var. alba Lange) that has the same strong odour.

Similar species

Young specimens could be confused with Stropharia aeruginosa, in addition to other poisonous species.

Distribution and habitat

Found in both deciduous, and coniferous woods, it is widespread in the temperate zones, occurring in Asia, Europe (August to December), 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.

Edibility

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.
