Aniseed Toadstool Identification – Clitocybe odora

Heads up

This post is part of our “100 Plants and Mushrooms” series. Here, you’ll see the mushroom’s main parts – its cap, gills or pores, stipe, and more – all with key identification features.

Aniseed Toadstool, or scientifically known as Clitocybe odora, doesn’t just surprise with its look but also with its scent. It has a unique and strong scent, similar to the spice aniseed. This scent comes from specific chemicals, namely p-anisaldehyde and a bit of benzaldehyde.

How to identify Aniseed Toadstool

Cap: Young Aniseed Toadstools start off with a light blue cap, which fades to grey as they get older. As they mature, the cap takes on a blue-green color, looking somewhat like a cup. It’s rough to touch. Its size can range from 1-3 inches across. With time, it becomes funnel-shaped and may even have wavy edges.

Gills: These are the underparts of the cap, where the spores come from. For the Aniseed Toadstool, they’re paler than the cap and fade as the mushroom gets older. These gills attach directly to the stem. This style of attachment is called “adnate”. Sometimes they might even run slightly down the stem, which we term as “decurrent”.

Stipe: This is the part that holds the cap up. It’s thick and textured with a pale-yellow shade. It stands 1.5-2.5 inches tall. It has no rings (those skirt-like structures on some mushrooms), and near the bottom, you might see it’s covered in white, soft fibers.

Spores: If you look under a microscope, the Aniseed Toadstool’s spores are smooth and oval-shaped. Their size is about 6-9 x 3.5-5.5µm.

Spore Print: The spore print of this mushroom is white.
