The Hidden World of Tiny Fungi in Margaret River: Marasmius, Mycena, and Rickenella Fibula

Margaret River is renowned for its breathtaking landscapes—its rugged coastline, towering forests, and lush vineyards. However, there is another hidden gem within this picturesque region: the tiny fungi that thrive in its forested trails. For those willing to venture off the beaten path and get low to the ground, a world of miniature wonders unfolds. The region’s rich biodiversity offers the chance to observe some of the most delicate, fascinating species of fungi—like Marasmius, Mycena, and Rickenella fibula—if you have the eagle-eyed attention to spot them.

Getting Low and Staying Alert

When hiking the Margaret River forests, if you want to discover the tiny treasures that lie at your feet, you need to slow down, focus, and get low. Fungi are often small, delicate organisms that can easily be missed if you're walking too quickly or not paying attention to the forest floor.

A good strategy is to crouch down and scan the ground carefully. Fungi often hide in the nooks of fallen logs, mossy patches, or the leaf litter that carpets the forest floor. You might need to bend down to get a closer look, and sometimes even lie flat to peer into the shadows where these mushrooms grow.

Pinwheels and Parachutes: Marasmius

One of the most striking fungi to be found in the Margaret River region is the pinwheel mushroom. These little gems have a unique, spiral-shaped cap that makes them resemble tiny, natural pinwheels. The caps, which are often white or pale-colored, curve and twist in mesmerizing patterns, creating an almost artistic appearance. They’re small—sometimes only a few centimeters in diameter—and often grow in clusters, making them look like a group of miniature windmills scattered across the forest floor.

Pinwheels can be tricky to spot, as they often blend into their surroundings. Their subtle colors and delicate shapes can be camouflaged by the forest litter. That’s why having a keen eye and patience is key. Once you spot a pinwheel, take time to marvel at its beauty, as these tiny fungi are incredibly intricate. They grow in a variety of habitats, but you'll most often find them in damp, shaded areas where moisture helps them thrive.

Mycena sp. A very common fungi species on the Margaret River trails.

Mycena: The Glimmering Wonders

Another remarkable type of fungus you'll encounter on the trails is the Mycena genus. These fungi are often tiny, with bell-shaped caps that can range in color from translucent white to pale lavender or pink. Mycena mushrooms have a delicate, almost ethereal quality, as their small, translucent caps often shimmer in the dim light of the forest.

Some species of Mycena are bioluminescent, which means they emit a faint glow in the dark. While you’re unlikely to see this glow during the daytime, these fungi still have an otherworldly quality. The small size of Mycena mushrooms—often only a few millimeters across—requires a sharp eye to spot them. They frequently grow in clusters, hidden beneath the decaying leaves or nestled among moss-covered rocks. So, get down to eye level, and take your time inspecting these hidden gems of the forest.

Rickenella Fibula: A Pop of Color

One fungi species that is hard to miss, thanks to its vibrant hues, is Rickenella fibula. This small mushroom, which typically grows in clusters, stands out due to its brilliant orange color. The bright, almost fluorescent appearance of Rickenella fibula is striking against the forest floor's otherwise muted browns, greens, and grays. Its slender stems and tiny caps make it an incredibly dainty species, yet it can create a dazzling display in the right lighting.

Rickenella fibula is often found growing on decaying wood or in mossy areas, making it another fungi that prefers a damp environment. When hunting for these fungi, pay close attention to the decaying branches or fallen trunks of trees, as this is where they tend to thrive. While they might catch your eye with their bright color, their small size means you need to get close to truly appreciate their intricate beauty.

The Art of Fungi Spotting

Fungi are often overlooked by hikers and trail-goers, but for those who take the time to appreciate the forest’s smallest details, they offer an entirely different perspective on nature. While the towering trees and expansive views are undoubtedly breathtaking, it’s the tiny fungi that add a layer of wonder to the experience.

To truly enjoy the process of spotting these minuscule marvels, slow down and be mindful of the world around you. The Margaret River Trails are teeming with life in every corner, from the tallest trees to the tiniest mushrooms. Pinwheels, Mycena, and Rickenella fibula are just a few examples of the fungi that call this place home. So, next time you venture out on a trail, remember to get low and keep your eyes peeled—you never know what tiny treasure you might discover at your feet.
