Recognizing their characteristics is essential for any forager to ensure a safe and enjoyable experience.

The Amanita genus includes some of the most notorious poisonous mushrooms, such as the Death Cap (*Amanita phalloides*) and the Destroying Angel (*Amanita bisporigera* and *Amanita ocreata*). These mushrooms often have a distinctive cap and stem structure, with a volva (cup-like base) and gills. The Death Cap, for instance, typically has a greenish-yellow or olive cap and can resemble edible species like young puffballs or other gilled mushrooms. Ingesting even a small amount of these Amanitas can cause severe liver and kidney damage, often leading to fatal outcomes. Foragers should avoid any Amanita species unless they are absolutely certain of their identification, and even then, extreme caution is advised.

Another highly toxic group to avoid is the Galerina genus, often referred to as "deadly skullcaps." These mushrooms are smaller and less striking in appearance but are just as dangerous. Galerina marginata, commonly found in Chicago's wooded areas, grows on decaying wood and has a brown cap with a rusty-brown spore print. Its unassuming look can make it easy to mistake for edible species like honey mushrooms. However, Galerina contains amatoxins, the same deadly toxins found in Amanitas, which can cause severe gastrointestinal symptoms, organ failure, and death within days of ingestion.

To avoid these toxic varieties, foragers should adhere to strict guidelines. First, never consume a mushroom unless you are 100% certain of its identification. Second, always cross-reference findings with reliable field guides or consult experienced mycologists. Third, pay close attention to key features like the presence of a volva, gill attachment, spore color, and habitat. Lastly, when in doubt, throw it out—it is better to err on the side of caution than risk poisoning. By staying informed and vigilant, foragers can safely enjoy Chicago's diverse mushroom population while avoiding the deadly Amanita and Galerina species.

In Chicago's wooded areas, such as the North Park Village Nature Center or the Cook County Forest Preserves, these toxic mushrooms can thrive alongside edible varieties, making proper identification paramount. While exploring these habitats, remember that toxic mushrooms often mimic edible ones, and their presence can vary by season and environmental conditions. For instance, Amanitas are more commonly found in late summer and fall, while Galerina species may appear year-round on wood debris. By familiarizing yourself with their characteristics and adopting a cautious approach, you can protect yourself and others from the dangers posed by these deadly fungi.
