Lobster Mushroom

• Lobster Mushroom is a mold living and feeding on the host mushroom
• Found throughout Oregon, mostly in old-growth forests

Lobster Mushroom (Hypomyces Lactifluorum) is not a real mushroom rather a mold or parasitic fungus, living and feeding on the host mushroom. The mold attacks and grows on Short-stalked White Russula (Russula brevipes) and Peppery Milky (Lactarius piperatus) transforming and changing their appearance and taste. The surface of the mushroom becomes bright orange or reddish-purple and unpalatable host mushrooms are transformed into a delicious edible.

Technically, Hypomyces Lactifluorum only parasitizes Russulas and Lactarius species. However, according to some sources, the mold could potentially parasitize some poisonous species. If you are not able to confirm the host, avoid this mushroom.


Lobster mushrooms are easily distinguishable, though, sometimes mistaken for a chanterelle. The entire body of the mushroom is fluorescent-orange (lobster-like) and smell like seafood. Older specimens can become bright-purple.

Gills of the host mushroom fused together converting into reddish blunt ridges or hard-visible pimples. The flesh is white and crisp.

Cap: Irregular, covered by bright orange to reddish mold.
Cap's Underside: Reddish blunt ridges or hard-visible pimples.
Spores & Print: Spindle-shaped, colorless.
Stem: Short, solid, covered by bright orange to reddish mold.
Flesh: White and crisp.
Habitat: Widespread in coniferous forests where Russulla and Lactarius are common.
Season: August-November.
Caution. Some guidebooks state that the host mushroom can be poisonous, making Lobster mushrooms toxic. But other sources assert that a chance that Hypomyces Lactifluorum attacks any other species is minuscule.

Where and When to Find Lobster Mushroom in Oregon

Lobster mushroom is found on the ground under a variety of trees, mostly under conifers, where its host mushrooms are common. Lobsters are found throughout Oregon, mostly in old-growth forests. In the wild, these fungi grow in coastal forests and in the woods of the Coast and Cascade Ranges.

Lobster Mushrooms are usually concealed among moss, leaf, and plant litter on the forest floor; so, look carefully.

Methods of Cooking

Lobster mushrooms are excellent for sautéing, frying, freezing, and drying. Use younger specimens.

Trim the dirty spots, carefully clean, and rinse mushrooms. Slice up the fruit bodies.
