Key Takeaways:

Identifying Poisonous Mushrooms in Maine

Identifying poisonous mushrooms in Maine is crucial to ensure your safety while foraging or enjoying the outdoors. Here are some key characteristics to look for when distinguishing poisonous mushrooms from safe varieties:


Many poisonous mushrooms in Maine have bright and striking colors, such as red, yellow, or blue. However, some safe mushrooms can also have these colors, so it’s important to look for other distinguishing features.

Cap and Stem

Pay attention to the cap and stem of the mushroom. Poisonous mushrooms often have a slimy or sticky cap and stem, while safe mushrooms have dry caps and stems. The stem of poisonous mushrooms can also have a ring or skirt around it, which is absent in safe mushrooms.

Gills and Pores

Take a closer look at the gills or pores on the underside of the mushroom cap. Poisonous mushrooms usually have dark gills or pores, while safe mushrooms have lighter colors. Some poisonous mushrooms also bruise or turn blue when damaged, which is a helpful distinguishing feature.

Spore Print

A spore print can help determine the color of a mushroom’s spores. To make a spore print, place the cap of the mushroom on a piece of paper or glass and leave it overnight. The spores will fall onto the paper or glass, revealing their color. This can be helpful in identifying certain species of poisonous mushrooms.

Remember, these characteristics are not foolproof and should be used in combination with expert guidance and reliable resources when identifying mushrooms in the wild.

“When in doubt, throw it out!”

If you are uncertain about the identification of a mushroom or have any doubts about its safety, it’s best to err on the side of caution and discard it. Stay safe and enjoy the natural beauty of Maine responsibly.
