What’s Popping?

Have you noticed the smooth, cap-shaped clusters popping out of the ground recently? Mushrooms are experiencing prolific growth right now. These enigmatic beings are all around us, yet most people do not understand their origins, their role in the sophisticated network of fungi, and their importance to our ecosystem.

Mushrooms sprout out of the ground in damp conditions, like we have been experiencing lately. They grow from spores, which are tiny, single-unit cells that are capable of reproducing without fusing with another cell. Fully grown mushrooms disperse spores into the air, which are then spread by wind. In damp, humid, and dark conditions, spores can grow rapidly into new mushrooms, sometimes becoming fully formed overnight.  

Mushrooms are part of larger organisms called fungi, which are integral to healthy ecosystems. Fungi perform an essential role in the decomposition of organic matter and help cycle nutrients throughout an environment. Mushrooms are the fruiting bodies seen above ground, but they are connected to other elements of fungi called mycelium, which live underground. Mycelium absorbs nearby organic matter and breaks it down into nutrients, such as phosphorus and calcium. This is vital to the growth of other organisms in the soil. Mycelium facilitates symbiotic relationships with plants and trees. By intertwining with plant and tree roots, mycelium gains access to sugars that feed them while in turn, they provide numerous benefits to their plant and tree partners. Because mycelium has vast networks, it has greater access to different nutrients in the surrounding soil than a plant might on its own. Through their relationships with fungi, plants and trees do not have to work as hard to get their nutrients. Natural environments with abundant fungi are able to thrive.

The mushrooms that have been popping up recently reveal the hidden wonders of fungi. They also give hope that after recent extreme environmental conditions, nature can regenerate and thrive again. So, as you walk around Oakland, take notice of the evidence of the fungi that are helping make the nature around us healthier.
