The Aniseed Toadstool (Clitocybe odora), is a blue-green mushroom that grows near deciduous and coniferous trees. They can be found growing in small groups along the side of tree roots. Many mushroom guidebooks suggest that it is edible, but a few expert mushroom hunters insist that young specimens should be avoided as can be confused with Stropharia aeruginosa.


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. 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. It has a strong scent and taste of aniseed, hence its name.

Distribution and habitatEdit

Found in both deciduous, and coniferous woods. It is widespread, and found in the temperate zones. Occurring in Asia, Europe, and North America.On the east coast of America it favours oak, and it is often abundant in the coniferous forests of the Pacific North West.


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. Make sure you observe every part before you put it in your basket. Also, check the stem and cut the cap to see if there are any fly larvae.
