Deadly webcap vs golden chanterelle: the orange lookalike that destroys kidneys

Quick answer

Under the cap, the deadly webcap has true gills that turn rusty cinnamon, a cobweb-like veil on young caps and yellowish veil bands on the stem, and drops a rusty brown print; a golden chanterelle has blunt, forked ridges that run down the stem, no veil, white flesh that tears into strings, and a pale print. The webcap's cap is also conical with a pointed bump, a chanterelle's flat to vase-shaped.

Deadly lookalike

The deadly webcap can be fatal.

Unlike the golden chanterelle, the deadly webcap (Cortinarius rubellus) contains orellanine, which destroys the kidneys. First Nature records that the first symptoms are usually delayed by two or three days, then flu-like symptoms, headache and vomiting, followed by kidney failure. In an Estonian series of seven orellanine poisonings, first symptoms could appear up to three weeks after the meal; six patients needed dialysis, and ten months later three were still on it.

FAQ

Common questions

Has the deadly webcap been mistaken for chanterelles?

Yes. First Nature records that its orange cap has led people to mistake it for chanterelles, including author Nicholas Evans and three family members, who suffered serious kidney damage in Scotland.

How long does orellanine poisoning take to appear?

First symptoms are usually delayed by two or three days and can take up to three weeks, which makes the mushroom easy to overlook as the cause.
