Featured Creature: Turkey Tails

Which fungi creature gets its name from a bird, helps heal internal wounds, and benefits people worldwide?

Turkey tails!

This year I took two trips – one to Nashville, Tennessee and another to the Northeast, specifically to White Mountain National Forest in New Hampshire (Abenaki Penacook land). Both of these places have more trees than I’m used to in Southern California, so I was instantly amazed by everything that grew throughout these forest wonderlands, especially the turkey tails.

A Bird Fungus

Turkey tails have three scientific names (depending on whom you ask): Trametes versicolor, Coriolus versicolor, and Polyporus versicolor. The common name, turkey tail, derives from the mushroom’s bands that resemble a wild turkey’s tail in color and shape. The ‘versicolor’ in the scientific names refers to the mushroom’s cap and its many colorations, from white, red, orange, to dark brown. This part of the mushroom has a fuzzy texture, almost as if it had tiny hairs all over, and is extremely flexible so you can bend it without breaking it. The ‘trametes’ in one of the scientific names refers to the genus, and the ‘polyporus’ refers to the placement of the pores. Turkey tails are a type of mushroom with pores on their undersides, in contrast to other mushrooms that have gills on their sides. 

Polyporous mushrooms tend to grow on dead logs. Turkey tails can be found on fallen trees in nearly every forest worldwide. They grow year-round, but will be extra easy to spot when it’s time to release their spores (in North America, this happens between May and December). You can identify a family of turkey tails by their banding pattern – all the offspring of one individual will sport the same pattern as their ‘parent.’ It’s a fungal fingerprint!

Healthy Tails

Apart from their colors and tail-like shapes, turkey tails are extra intriguing for their health benefits. They contain numerous properties, including:

  • Antioxidants, such as phenols and flavonoids, which reduce inflammation and oxidative stress (an imbalance in our systems when we’re unable to detoxify).
  • Protein-bound polysaccharides (carbohydrates), one being Krestin which promotes immunity to toxins and regulates immune responses. It also activates white blood cells which protect our bodies from harmful bacteria.
  • Prebiotics, which foster beneficial bacteria. They also regulate our gut microbiome, leading to better digestion and lower cholesterol.
  • Fiber, found in many mushrooms, which also promotes better digestion.

People who consume turkey tail extract report better athletic performance, less fatigue, and when combined with chemotherapy, increased effectiveness of cancer treatments. By promoting our body’s natural production of beneficial compounds, and counteracting substances that harm us, turkey tails improve overall health when taken as a supplement.

Turkey Tea

There are some mushrooms you can eat right after foraging, but turkey tails are not one of those. To receive the many benefits from Trametes versicolor, you’ll need some prep work.

Due to the thick and woody structure of turkey tails, they’re extremely difficult to consume and, therefore, essentially inedible. However, when you dry them out and grind them to create a powder, you can reap their benefits in no time. After letting them dry, and cleaning them to ensure no dirt or insects remain, you can grind them up. The resulting powder can be put into capsules to be taken as a pill-based supplement, or you can brew some tea to extract the most beneficial compounds. Other mushrooms require a process that involves alcohol before eating, but not turkey tails! 

If you’re feeling creative, you can also add the powder to your everyday meals. Since these mushrooms are relatively plain in flavor, people will add the extract to smoothies, oatmeal, or soup to add taste. The powder can be stored for years as long as it’s in an airtight container and kept in the pantry, away from the heat and sun.

We can thank ancient teachings for these turkey tail tips. Traditional Chinese medicine is the first documented time people practiced the art of extracting beneficial compounds from turkey tails. They originally used the extract to treat lung, liver, and spleen issues.

If you try any of these recipes, let us know your experience (you can email us at staff@bio4climate.org)!

A word of caution: If you do decide to forage, for turkey tails or any other organisms, please do so with consideration for the local ecosystem’s health. Only forage what you need, so as to not exploit natural resources.

It’s also best to forage with others when starting out (and it’s more fun this way!). You could join a local foraging group to gain access to resources regarding ecosystem health and potential contaminants in the area. This way, you can learn how to forage without causing harm to your body, other people, or the landscape.

Tea time, anyone?

Featured Creature: Clamworm

What sort of worm is festooned with sensitive tentacles all the way down its sides and – though it can’t bark – has a nasty bite?


That would be the “clam worm” or alitta succinea, a denizen of estuarial waters.

Alternative names

I’ve always called them “seaworms” but they are normally known as “clam worms,” “ragworms,” “sand worms” or “pile worms”, and they are a species of annelid, the phylum of segmented worms.

Size and habitat

The clam worm can reach up to 15 cm (almost 6 inches) but most are smaller. This worm is reddish-brown in color, and has four eyes, tentacles or flaps all the way down its sides which can also function as gills, and sensory feelers at its head. 

When hungry, it uses a long internal mouthpart called a proboscis, along with two hooks that unfold to capture and then draw prey into a mouth at its front end. These worms are themselves an important food source for fish and crustaceans, and are widely used as fishing bait. Their typical habitat is rocks, vegetation, reefs, and mud. They burrow into the mud or sand, or hide under rocks, to be safe from many potential predators.

My own first encounter 

In my early teens, my father and I used to fish for striped bass with a flashy lure with a seaworm strung on a hook behind it. “Here’s how you do it,” my father counseled me. “Just poke the worm in its mouth and, as soon as it opens, insert the hook point.”

“Owww!!!” I exclaimed. “This worm bit me!” My father laughed, almost as hard as during one of my earlier ‘learning moments’ in a Maine field, when halfway over an electric fence I got shocked! On neither occasion did I expect the bite, but I eventually learned to be more careful. Those pincers were sharp! 

The pincers’ zinc content makes them strong while keeping them very lightweight. They certainly drew my blood that first time! The fish surely liked these worms, but eventually I gave them up for flies (less messy and easier on the worms).

Spawning behavior 

During the full and new moon tides in the late spring and early summer, these clam worms undergo a process called epigamy, which enlarges their parapodia (tentacles) so they can swim more easily to the surface to release their eggs and sperm, at which point their bodies rupture and disintegrate. Talk about dying to reproduce! One hopes at least they have fun on their way out. Their fertilized eggs then settle to the bottom and hatch into a new generation.

Replacement parts 

These worms can replace various body parts, and make new worms from broken pieces, such as when their tails are pulled off by a predator. But rear body segments are more readily repaired than heads, which are much harder to replace – those of us our heads still on can probably relate!

Check out a short video on clam worms and their special properties:

Their role in marine ecosystems 

The tunneling and boring of marine worms irrigate and oxygenate the shallow water pools encouraging beneficial plant and algae growth. Whether it’s in tide pools, lowland waters or oceanic reefs, the marine worm’s primary ecological contribution is as sustenance for aquatic animals further up the food chain. Species of these worms respond quickly to increased amounts of pollution in the water and on the ocean bottom. Their presence or absence may indicate important changes in the marine environment.

Some subspecies are at risk, but clam worms are OK 

Most of this species is doing just fine, at least when not being used for bait or eaten by humans. However, you might just want to think twice before skinny dipping on May-June new or full moon tides!

What brainless creature can learn, problem solve, and even hold down a job? 

The slime mold!

Slime molds are eukaryotic organisms (a type of organism with membrane bound organelles, like nuclei) that can live either as single-celled individuals or clumped together in large aggregates, called plasmodial slime molds. These strange creatures have long fascinated humans, and it’s no surprise why. 

The individuals of the species Physarum polycephalum live as solitary cells for a period of time and then come together as plasmodial slime molds, before splitting again to reproduce. Because of this strange cellular structure across their life cycle, they have been a challenge to classify, and were previously grouped as fungi. There are over 900 different species of slime molds, which come in different shapes, sizes, and colors.

Since they are single-celled organisms, slime molds do not form nervous systems or organs like a brain. However, when they live as plasmodial slime molds, the many nuclei form a network within a single cell membrane that can process sensory information independently and share that information with each other. In this way, they have been shown to learn where displeasing or toxic substances are within an area and then avoid that area in the future, remembering such stimuli and passing it on. They can play the world’s most successful game of “telephone”!

How have slime molds become known for problem solving? 

Because of their ability to group together and send out strands of slime, slime molds are adept problem solvers. They can sense the chemical traces of food sources in the air the way that we sniff out food with our senses of smell, and pulse out toward that signal. 

Researchers have set up experiments where they placed oat flakes, a food greatly enjoyed by slime mold, at different points in a dish, and observed the slime mold find the shortest route between them. Slime molds can map out the most efficient network of pathways between dozens of different points of interest, organically figuring out the solution to a problem of tremendous computational complexity. In different experiments, they have mimicked the Tokyo train network, as well as British and Iberian road networks.

Take a look at their movement and decision making:

What else can slime molds do?

Scientists fascinated by slime molds’ power have wondered about the possibility of “computing” with slime molds. A graduate student in the UK has powered a microchip with a slime mold sample, and other British researchers have created a robot that is controlled by a slime mold at its center reacting to light, which it likes to avoid. 

Perhaps strangest still is the decision by Hampshire College to give slime mold a faculty appointment. A sample of Physarum Polycephalum is the school’s resident non-human scholar, and it does research on problems posed to it by students modeling various policy questions. 

Though their intelligence is quite different from our own, it is certainly worthy of respect, and can teach us a thing or two. For more interesting looks at slime mold, check out the work of Heather Barnett, who spoke at our Voices of Nature conference in 2018, and recorded a popular TED Talk on the subject. As research on this intriguing creature reminds us, intelligence comes in many life forms.
