Candy Cap

Lactarius rubidus

Edible

Also called western candy cap.

The candy cap is a small, rusty orange-brown milk cap from the Pacific Coast that smells of maple syrup or burnt sugar when dried. It grows in oak and conifer woods during the winter rainy season and is collected as a flavoring for desserts.

The tell

Small orange-brown milk cap with thin, watery latex that smells strongly of maple syrup once dried.

Field marks

What to look at

Cap, underside and stem show in a photo. The spore print does not, and it is often the deciding check.

Cap
Convex to flat, often with a small central bump or a shallow dip. Orange-brown to cinnamon or rusty red, dry and slightly wrinkled.
Underside
Pale orange to pinkish-buff gills, attached to slightly running down the stem.
Stem
Slender, brittle, hollow and colored like the cap. No ring and no cup.
Flesh
Thin and brittle. The latex is clear and watery, like skim milk or whey, and does not change color. Fresh specimens smell faint; dried ones smell strongly of maple syrup.
Spore print
Whitish to cream or pale yellow.
Size
Cap 3/4 to 2 1/2 inches (2 to 6 cm) wide; stem 1 to 3 inches (2.5 to 7.5 cm) tall.

Where and when

Where and when it grows

Habitat
Under oaks, tanoaks and conifers in coastal forests, often on rotting wood, needle litter or moss.
Grows on
Soil and well-rotted woody debris.
Season
Fall through early spring, during the Pacific Coast rainy season.
Range
Pacific Coast, mainly California; eastern candy caps are related species such as Lactarius camphoratus.

Lookalikes

What the candy cap gets confused with

Each card says how to tell the two apart.

  1. Compare side by side
  2. Red hot milk cap (Lactarius rufus)

    Similar color but larger, with white latex rather than watery latex, and no maple smell when dried.

  3. Eastern candy cap (Lactarius camphoratus)

    An eastern relative with a similar sweet smell when dried, found under conifers and hardwoods east of the Rockies.

Edibility

What the field guides say

Edible

Field guides list the candy cap as edible and describe its use as a flavoring, usually dried, in cookies, ice cream and syrups. The maple smell comes from sotolon, the same compound that gives fenugreek and maple syrup their scent. Its dangerous confusion is with small brown mushrooms such as Galerina, which contain amatoxins.

This page states what field guides record. It is not advice to eat, taste or handle anything, and a photo cannot settle edibility. If someone has eaten a wild mushroom that may be toxic, call poison control (1-800-222-1222 in the US) right away, before symptoms start: the deadliest species act hours later.

FAQ

Questions about the candy cap

Why do candy caps smell like maple syrup?

They contain sotolon, an aroma compound also found in fenugreek and maple syrup. The smell is weak in fresh specimens and becomes strong once the mushroom dries.

Where do candy caps grow?

In oak, tanoak and conifer forests along the Pacific Coast, mostly in California. They fruit during the rainy season, from fall into early spring.

What does a candy cap look like?

A small orange-brown cap on a brittle, hollow stem of the same color, with pale gills. Broken gills release thin, watery, whey-like latex, and dried specimens smell of maple syrup.
