Where To Find

Grows scattered in deciduous woods. Eating raw wild mushrooms is never recommended, but if you think you might have found a Lactarius piperatus (that is, if your mushroom fits the description as an all-white funnel-shaped mushroom with very crowded white gills), you can touch a tiny drop of the "milk" to your tongue, then spit it out. If it is spicy-hot, you have a peppery milky!

Considered edible. While this is an edible mushroom, it is really too peppery to eat and enjoy. However, it can be dried and ground to a powder to use like pepper.

Life Cycle

This species is mycorrhizal: It exists most of the time as a network of cells (mycelium) connected to tree roots, in a symbiotic relationship with the tree. (Many trees fare poorly without their fungal partners.) When ready to reproduce, the mycelium sends up the mushroom — this is the reproductive structure. Spores are produced in these structures and are released to begin new mycelia elsewhere. The mycelium of a mushroom can live for decades.

Humans have eaten mushrooms for thousands of years, in many cultures, for various purposes. Sometimes they are eaten as food or for medicinal properties. This mushroom can be used as a seasoning. Be absolutely sure of your identifications before you consume wild mushrooms!

This is one of many fungus species that help nourish forest trees through symbiosis. The netlike fibers of the fungus cover the surface of a tree’s roots, increasing the surface area and the roots’ ability to absorb water and nutrients. In return, the tree shares nutrients with the fungus.

About Mushrooms in Missouri

Mushrooms are a lot like plants, but they lack chlorophyll and have to take nutrients from other materials. Mushrooms are neither plants nor animals. They are in a different kingdom — the fungi. Fungi include the familiar mushroom-forming species, plus the yeasts, molds, smuts, and rusts.

Always be cautious when eating edible mushrooms. Be absolutely sure of the ID, and only eat a small amount the first time you try it to avoid a reaction..
