Candy cap mushrooms are small to medium-sized fragile mushrooms known for their aromatic properties and frequently used in cuisine for flavoring rather than as an item of sustenance. Candy caps have a latex that resembles very watery milk; this does not change the color of the flesh and does not change color even when exposed to air. Candy caps are often used in dried forms, and when re-hydrated, produce a sweet liquid that can be used in pancakes, waffles, cookies, and bread. Candy cap also compliments many savory dishes such as fish and pork, in particular smoked dishes. Due to their versatility, they are a favorite mushroom among chefs. On the downside, it is quite laborious to collect sufficient quantities of these fragrant mushrooms.
There are different Candy caps, but the three that are most referred to for their sweetness are Lactarius fragilis, Lactarius camphoratus and Lactarius rubidus. Lactarius camphoratus, is not nearly as strong in flavor; some suggest it is a good substitute, but others argue that once you have experienced the ‘real thing’ of Lactarius rubidus you would not go back. All three of these Candy cap species are found in North America, more Candy Caps may be revealed in the future. Lactarius rufulus is another contender for the Candy cap, but this is not agreed by all due to earlier reports of the flavor being subacrid and lack of the maple-like aroma. It is also a larger species of the ‘Candy cap’ which tends to have a redder caps and is found only under oak trees.
These mushrooms are primarily known for their odor, and the chemical that causes this scent was identified in 2012 by William Wood, from extracts of Lactarius rubidus. The compound was identified as quabalactone III. When Lactarius rubidus dries quabalactone III hydrolyzes and becomes sotolon, the smell is even more potent, and this is what gives maple syrup and curry their scent. The smell is so strong that they are reported to leave their scent in a large room for several days.
Lactarius camphoratus tastes more curry-like than Lactarius fragilis and L. rubidus; it is very mild in comparison. Lactarius camphoratus is also found in Midwest America, unlike the other Candy caps; it is also found in Northeastern America, Europe, and Asia. Lactarius camphoratus is darker than its fellow Candy caps with a deeper shade of reddish-brown. It grows up to 4cm in diameter and up to 6cm tall.
Lactarius fragilis is a lighter color than its fellow Candy caps, appearing reddish-brown to a light brown with yellow tones on its gills. Lactarius fragilis is found in Northeastern America. The maple-like smell is strong even when fresh, becoming stronger when dried. Grows up to 4cm in diameter, and up to 6cm tall like Lactarius camphoratus.
Lactarius rubidus is an attractive mushroom colored burnt orange and frequently seen growing on rotting conifer wood. Found in Northwestern America and also in California among conifer and oak trees. The maple-like smell of Lactarius rubidus is strong, but only when dried, not fresh, this may cause confusion during identification. Lactarius rubidus can become slighter larger than its fellow Candy caps growing up to 8cm in diameter and up to 7cm tall. It also has orange tones on its gills.

Candy Cap Mushroom Look-Alikes
The Galerina mushrooms are little brown mushrooms that must not be confused with Candys caps because Galerina marginata is deadly; it has a rusty brown spore print when compared to the white or pale yellow spore print of Candy caps. Candy caps can be identified from other types of little brown mushrooms by their stipe, which is brittle and snaps off rather than being flexible. For this reason it recommended that the Candy caps are gathered by hand and broken at the stem. The brittleness is caused by cells called sphaerocysts, which are specific to Lactarius. Another defining feature is the milky latex produced by the Candy cap, which remains white even when oxidized.
Lactarius xanthogalactus is commonly misidentified as a Candy cap; this impostor is found in the Western USA. The cap of Lactarius xanthogalactus is more grey than Candy caps, although still orange. Furthermore, its lactose quickly turns yellow, unlike Candy caps, which remain white. Lactarius xanthogalactus is poisonous, so correct identification is necessary; the confusion arises because it grows near Candy caps. Lactarius helvus and Lactarius aquiflus are very aromatic, Lactarius helvus smells of fenugreek; however, they should be avoided because they may be mildly toxic.
