The chanterelle is a mushroom everyone loves: it rarely goes maggoty, it keeps for days, and it is hard to confuse with anything dangerous. Hard, but not impossible. It is worth knowing the two mushrooms that can impersonate a chanterelle, and the single feature that unmasks them.
Ridges, not gills
The chanterelle, Cantharellus cibarius, has a uniform yellow-orange colour across the whole fruit body: cap, stem and underside alike. The cap is convex at first, then funnel-shaped, with a wavy, inrolled margin. The key feature is underneath: these are not gills but thick, forking ridges, that is folds, which run smoothly far down the stem. The flesh smells fruity, faintly of apricot, and does not blue.
The false chanterelle: a gentle impostor
The false chanterelle, Hygrophoropsis aurantiaca, earns its name. It has a more intense orange colour, a velvety cap, and underneath, true gills: thin, crowded and regularly forked, sharply set off from the stem. It is not deadly, but it upsets some people’s stomachs and, beyond that, it simply does not taste like a chanterelle.
More dangerous is Omphalotus olearius, the jack-o’-lantern, a lookalike that grows in clusters on wood and stumps, with sharp, crowded, non-forking gills. In Poland it is rare and heat-loving, but confusing it with a chanterelle leads to severe poisoning. The key is the same: gills versus ridges, and the substrate, because a chanterelle grows from the soil, not from wood.
Uniformly yellow-orange, stem and underside too
Thick, forking ridges running down the stem
Fruity smell, faintly of apricot
Grows from the soil, singly or in groups
Intensely orange, velvety cap
Thin, crowded, regular gills, sharply set off from the stem
Bland smell, not fruity
Often on conifer litter and rotting wood
One observation is enough
Underside of the cap: thick, blunt, forking ridges mean chanterelle, thin sharp gills mean false chanterelle.
Transition to the stem: on a chanterelle the ridges run smoothly down, on the impostor the gills stop sharply.
Substrate: a chanterelle grows from the soil, clusters on wood are a warning sign.
Smell: a chanterelle smells fruity, the impostors are bland or featureless.
The chanterelle is a mycorrhizal mushroom and grows from the soil, in symbiosis with trees, never massed on a trunk or log. Treat bright orange mushrooms sprouting in clusters straight from wood with suspicion, however tempting the colour looks from a distance.
The good news is that once you learn to look at the ridges instead of the colour, the chanterelle becomes one of the safest mushrooms in the forest. That is exactly why it is recommended to beginners, but the recommendation only holds once you know the difference between a ridge and a gill.
Cut a chanterelle lengthwise in half. A real one is pale, fibrous and solid inside, and the colour of the ridges flows smoothly into the stem. The cut also reveals any maggot trails, which chanterelles rarely have anyway.
