Florida is home to a diverse array of beautiful and fascinating wildlife, including an assortment of unique and colorful mushrooms. However, some of these eye-catching fungi are not only dangerous but can be potentially life-threatening if ingested. In this guide, we will discuss some of the most poisonous mushrooms found in Florida and how to identify them, as well as provide guidance on what to do if you suspect that you or someone you know has consumed a poisonous mushroom.

Identifying Poisonous Mushrooms in Florida

Florida is home to many different kinds of mushrooms, but only a handful of them are truly hazardous to humans. Some of the most toxic mushrooms found in Florida include:

Amanita Phalloides (Death Cap)

This highly poisonous mushroom is commonly found in Europe, but has also been reported in Florida. Its cap is usually 2-6 inches in diameter, and ranges in color from greenish-yellow to olive-brown or white. The gills are white, while the stalk is beige. Consuming this mushroom can lead to severe liver and kidney damage, as well as potentially fatal complications.

Galerina Marginata (Deadly Galerina)

This small, unassuming brown mushroom is found in various regions across Florida. It is often found growing on rotting wood, such as logs and stumps. The cap is brown, while the gills and stalk are both beige. This mushroom is particularly dangerous due to its resemblance to many edible fungi, and it contains a potent toxin that can lead to liver and kidney failure if ingested.

Chlorophyllum Molybdites (Green-spored Lepiota)

Commonly found in Florida’s lawns and fields, this large, white mushroom is notable for its green spores. The cap is white with light brown scales, while the gills may appear white to gray or greenish in color. Although not typically fatal, consuming this mushroom can result in severe gastrointestinal distress.

What To Do If You Suspect Mushroom Poisoning

If you believe that you or someone you know has ingested a poisonous mushroom, it is crucial to seek medical attention immediately. Symptoms of mushroom poisoning can vary but may include:

  • Nausea and vomiting
  • Diarrhea
  • Abdominal pain and cramping
  • Weakness and dizziness
  • Jaundice (yellowing of the skin and eyes)
  • Seizures

Do not wait for symptoms to appear, as they may not manifest until several hours after consumption, and the delay in treatment can be dangerous. If possible, safely collect a sample of the suspected mushroom for identification by medical professionals or mycologists.


While Florida is home to many fascinating and visually appealing mushrooms, it is essential to exercise caution and make sure to properly identify any wild mushroom before consumption. By being vigilant and knowledgeable about the deadly and poisonous mushrooms found in Florida, you can avoid dangerous situations and possible tragedy.
