Show Me Pictures of Mushrooms: How to Tell What You’re Actually Looking At

Show Me Pictures of Mushrooms: How to Tell What You’re Actually Looking At

You’re walking through a damp forest after a heavy rain, and suddenly, there they are. Little pops of white, red, and brown poking through the leaf litter. Your first instinct? Grab your phone and search for someone to show me pictures of mushrooms so you can figure out if you've found dinner or a trip to the emergency room.

It’s a wild world down there on the forest floor.

Mushrooms aren't just plants. In fact, they aren't plants at all. They are the fruiting bodies of fungi, a kingdom of life that is more closely related to humans than to sunflowers. When you look at a photo of a mushroom, you're only seeing the "apple" of a much larger "tree" that lives underground as a web of mycelium.

The Most Photogenic (and Dangerous) Mushrooms

Most people, when they want to see pictures of mushrooms, are looking for the iconic red one with white spots. That’s the Amanita muscaria, or the Fly Agaric. It looks like it belongs in a Mario game or a fairy tale. And while it’s beautiful to photograph, it’s actually toxic. It contains ibotenic acid and muscimol, which can cause hallucinations, nausea, and a generally bad time.

Nature is funny like that. The prettiest things are often the most "stay away."

Then you have the Morel. If the Fly Agaric is the beauty queen, the Morel is the wrinkled, brain-looking cousin. Foragers go absolutely nuts for these in the spring. They have a pitted, honeycomb-like cap that is truly unique. If you see a picture of a mushroom that looks like a tiny, beige sponge on a stick, you’re likely looking at a Morchella species. They are delicious, but here’s the kicker: there are "False Morels" (Gyromitra) that look similar but can actually be fatal if prepared wrong.

Basically, never trust a photo alone.

Identifying by the Gills and Pores

If you really want to get into the nitty-gritty of mushroom photography and identification, you have to look under the hood. Or, well, under the cap.

  • Gilled Mushrooms: These are what most people think of. Think of a White Button mushroom from the grocery store. Underneath the cap, there are thin, paper-like ridges called gills.
  • Pore Mushrooms (Boletes): Instead of gills, these have a spongy surface made of tiny tubes. If you see a picture of a mushroom with a thick stem and a yellow or brown "sponge" underneath, it’s probably a Bolete. The King Bolete (Boletus edulis) is the holy grail for many.
  • Teeth Fungi: Some mushrooms, like the Hedgehog mushroom, have tiny little "teeth" or spines hanging down. It’s kinda weird looking, honestly.

Visuals are a great starting point, but expert mycologists like Paul Stamets or the late Gary Lincoff always emphasize that photos are just one piece of the puzzle. You need to know the smell, the texture, and even what kind of tree it was growing next to.

Why Some Mushrooms Glow in the Dark

Ever seen a picture of a mushroom that looks like a neon green lamp? That isn't Photoshop. It’s bioluminescence.

Species like the Jack O’ Lantern mushroom (Omphalotus olearius) or the Ghost Fungus (Omphalotus nidiformis) contain an enzyme called luciferase. It’s the same stuff that makes fireflies glow. Why do they do it? Some scientists think it’s to attract insects that will then spread the mushroom's spores. It's basically a neon "open" sign for bugs.

If you’re looking at pictures of these, they usually require long-exposure photography to capture the glow, so don't expect them to look like a flashlight if you find one in the woods at night. It’s more of a ghostly, faint green shimmer.

The Weird Ones: Slime Molds and Bird's Nests

Sometimes, people ask to see pictures of mushrooms and they end up seeing something that looks like it's from another planet.

Have you ever seen the Bird's Nest fungus? It literally looks like a tiny bird's nest with "eggs" inside. The eggs are actually peridioles, which contain the spores. When a raindrop hits the nest, it splashes the eggs out, spreading the fungus.

Then there’s the "Bleeding Tooth Fungus" (Hydnellum peckii). It’s a white, lumpy mushroom that oozes a thick, red liquid that looks exactly like blood. It’s not blood, of course—it’s just a result of a process called guttation—but it makes for a terrifyingly cool photo.

Getting the Best Photos Yourself

If you’re out there trying to take high-quality pictures of mushrooms, you need to get low. Like, stomach-in-the-mud low.

Most people take photos from a standing position, looking down. That’s boring. To get that "National Geographic" look, you want to get the camera level with the mushroom. This shows the scale and the detail of the stem (stipe) and the gills.

Use a piece of white paper or a small reflector to bounce some light under the cap. Mushrooms often grow in dark, shaded areas, so the underside is usually in a deep shadow. A little reflected light can reveal the intricate patterns of the gills that make the photo pop.

The Importance of Spore Prints

When photos aren't enough, experts use spore prints.

You take the cap of the mushroom, lay it gills-down on a piece of paper (half white, half black is best), and leave it overnight under a bowl. In the morning, you’ll have a "dust" pattern. The color of that dust—white, brown, rusty, or even green—is a major identification key.

If you see a picture of a mushroom that looks like a regular field mushroom but the spore print is green, you’re looking at Chlorophyllum molybdites, also known as "The Vomiter." The name tells you everything you need to know about why identification matters.

Common Misconceptions About Mushroom Visuals

One of the biggest mistakes people make when looking at pictures of mushrooms is thinking that "if an animal eats it, I can eat it."

This is dangerously wrong.

Squirrels can eat the Death Cap (Amanita phalloides) without any issues. If a human eats it, their liver will basically dissolve. Just because a photo shows a slug snacking on a mushroom doesn't mean it's safe for your dinner plate.

Another myth? That bright colors mean a mushroom is poisonous. While many toxic mushrooms are bright, some of the most delicious ones (like Chanterelles) are bright orange, and some of the deadliest (like the Destroying Angel) are pure, innocent-looking white.

Practical Steps for Aspiring Mushroom Lovers

If you've spent the afternoon looking at pictures of mushrooms and now you're hooked, here is how you actually get started in the hobby without accidentally poisoning yourself.

First, buy a local field guide. A book written specifically for your region is worth ten times more than a general "mushrooms of the world" book. The species in the Pacific Northwest are vastly different from the ones in the UK or the Appalachians.

Second, join a mycological society. There are groups in almost every major city. They go on "forays" where you walk through the woods with people who actually know what they're doing. It’s the fastest way to learn.

Third, use apps like iNaturalist or Seek, but use them as a suggestion, not a final answer. These apps use AI to identify photos, and while they are getting better, they still make mistakes. Use them to narrow down the genus, then go to your books to confirm the species.

Finally, start a "photo herbarium." Instead of picking every mushroom you see, take high-quality photos from multiple angles: the top, the side, and the underside. Note the date, the location, and what trees were nearby. Over time, you’ll start to recognize the patterns in your own neighborhood.

The world of fungi is massive, weird, and incredibly vital to the planet's health. Whether you're just looking at pictures or heading out into the mud, there is always something new—and probably a little bit strange—to discover.
