Bird’s nest fungi (genus Nidulariaceae) resemble small nests filled with “eggs,” which are actually spore packets. These saprotrophic fungi thrive on decomposing wood, such as old Douglas-fir cones. When raindrops land in the cup at the right angle, the spore packets are splashed out, dispersing and continuing their life cycle. Photo by Ian Nelson.

The Fungi Kingdom is a truly fascinating and somewhat mysterious group of organisms that includes an extraordinary variety of life forms such as yeasts, molds, lichen, and, of course, the ever-popular mushrooms. While many people see fungi primarily as “decomposers” that break down organic material, their contributions to human society are profound and far-reaching.

Fungi play a crucial role in nutrient cycling within ecosystems and provide essential food products that many of us enjoy, like bread, wine, and cheese. Moreover, their medical applications are significant, particularly with the discovery of antibiotics like penicillin — a breakthrough that has saved countless lives.

Summer’s Journey

My family and I have been photographers for as long as I can remember. I enjoy spending time taking an abundance of photos of the same subject in hopes of capturing that elusive perfect shot. It’s the combination of angle, subject, and lighting that produces a one-of-a-kind image. I have far more plant photos on my phone than anything else, as they are such obedient subjects; I can always rely on them to stay still!

Shaggy mane (genus Coprinus) mushrooms can quickly change from solid to a black gooey mess as they liquify their gills to disperse spores more effectively. This process gives them the nickname “Inky Cap.” Photo by Summer Swallow.

My own journey into the world of fungi began during a biology lab course at Santa Rosa Junior College. It was there that I first delved into the evolutionary biology and ecological roles of fungi, examining various specimens through a microscope. This hands-on experience sparked a curiosity and appreciation for these remarkable organisms that I hadn’t expected.

Studying the Fungus Amongus

I encourage you to step outside and explore the fungi growing in your neighborhood throughout different seasons. Pay particular attention to the base and trunks of older or dying trees; these areas often reveal a hidden world of fungal life that thrives after rainfall. You might be astonished by the diversity of shapes, sizes, and colors you encounter. Perhaps, like me, you will feel inspired to delve deeper into the study of these intriguing organisms that flourish in the damp conditions following winter rains.

If you’re interested in fungi and other organisms, I recommend visiting iNaturalist.org. It’s a community-driven platform where you can upload and share photos of mushrooms and creatures you find. You’ll receive feedback from experienced mycologists and connect with fellow enthusiasts. Also, consider downloading the iNaturalist app, which is great for learning about local biodiversity and connecting with nature lovers. It’s a valuable resource for exploring the fascinating world around you.

Pixie cup lichen, belonging to the genus Cladonia, is part of the family Cladoniaceae and is found globally. Cladoniaceae is one of the largest families of lichen-forming fungi, with over 500 species described. These lichens are characterized by red dots, which are actually their apothecia, structures that contain millions of spores. Photo by Summer Swallow.

FUNgal Facts

• The fungal body consists of a network of tiny filaments called hyphae. Mycelium, an interwoven mass of these hyphae, is often found beneath the surface. So, next time you dig up a mushroom or flip over a rotting log, look for loose white threads — that’s mycelium!
• The cell walls of fungi are made of chitin, a material providing strength and flexibility. Interestingly, chitin also constitutes the exoskeletons of insects and arthropods.
• Mushrooms are akin to the apple you pick from an apple tree; they’re the fruiting body. The “tree” of the mushroom is actually the mycelium, which is underground.
• An incredible 95% of flowering plants establish a mutually beneficial relationship with fungi known as mycorrhizae. These fungi attach to plant roots, enhancing the plant’s ability to acquire nutrients from the soil while receiving carbohydrates in return.
• Lichens are not just a single organism; they are a fascinating community of organisms living together, including fungi and photosynthetic partners like algae and cyanobacteria!
• The green color of lichens comes from their photosynthetic partners—algae or cyanobacteria—that use sunlight to create food!
• Want to know what mycorrhizae means? It comes from Greek, where “myco” means fungus and “rhizas” means root!
• Research has shown that yeasts and bacteria are also part of the lichen community. Yeasts play a crucial economic role, especially in agriculture-focused areas like Sonoma County. Without our yeast friends, we wouldn’t have beer or wine!
• Fungi are essential decomposers in our world, as they break down organic matter into smaller pieces that other organisms can utilize.
• While over 100,000 fungi species have been identified and named globally, it’s estimated that there may be closer to 1.5 million fungi species awaiting discovery!

Tube lichen (genus Hypogymnia) is a common type of lichen found in various habitats throughout California. This genus is notable for being hollow inside! If you break open one of its branches, you’ll discover that it is indeed hollow, and you’ll also notice the color of the inner wall, which can help in identifying the specific species.
