Fungi are nongreen eukaryotic species that have no means of movement, reproduce by spores, and obtain food by breaking down and extracting nutrients from their surroundings. Fungi are categorized according to their form and reproduction process. Threadlike fungi, sac fungi, and imperfect fungi make up the majority of fungi species. Mold is a threadlike fungus that resembles wool or cotton in appearance. The majority of fungi in this group live in soil and decompose organic matter. Fungi known as sac fungi make up the largest community of fungi. Yeasts, powdery mildews, truffles, and morels are among them. The most well-known fungi are club fungi, which are umbrella-shaped mushrooms. All fungi species that don’t quite fit into the other groups are included in the imperfect fungi community.

This is a rare little puffball that I would never have discovered if I hadn’t been invited to participate in the mycology section of a Bioblitz this past weekend at Alderville First Nation Black Oak Savanna/Tallgrass Prairie. The site, which is situated south of Rice Lake, includes remains of Canada’s easternmost prairie. It’s one of Ontario’s most endangered plant species, so even though there hadn’t been much rain lately, I was eager to see what fungi I could find.
My friend Ulli and I accompanied our guide, Radek Odolczyk, into the grasslands, stopping first at an area that had recently undergone a prescribed burn, which was done to imitate the natural restorative grass fires that occur on tallgrass prairies. Since growth was scarce and the earth had been parched by a heat wave, the only things we discovered in this field were a couple of shriveled Agrocybe pediades and three similarly desiccated fairy ring mushrooms (Marasmius oreades). We shifted our hunt to an area with more proven growth because we were already sweating.

The oak savanna is one of North America’s most endangered habitats, with just 0.02 percent of its original area left. We investigate whether oak savanna has a distinct population of ectomycorrhizal fungi, a higher diversity of ectomycorrhizal fungi, or a higher relative abundance of ascomycete fungi when compared to adjacent areas where oak savanna has been transformed to oak forest due to a lack of fire. Cenococcum geophilum and other ascomycetes, as well as Cortinarius, Russula, Lactarius, and Thelephoraceae, dominated the overall fungal population. Aboveground (sporocarp surveys) and belowground (RFLP detection of ectomycorrhizal root tips), oak savanna mycorrhizal populations were distinct from oak forest communities; nevertheless, overall diversity was not higher in oak savanna than oak forests, and there was no evidence of a greater abundance of ascomycetes. Despite having lower local diversity than oak forests, the presence of a distinct fungal population suggests that oak savanna plays an important role in preserving regional ectomycorrhizal diversity.

Mycorrhizal networks, which weave in and out of tree roots, are almost certainly as old as the trees themselves. A basic matter of biochemistry is almost definitely the explanation for the alliance’s existence. Photosynthesis was a miraculous ability that plants possessed when they first colonized land, and it totally changed the history of life on this planet. They also need to find vital nutrients for survival, metals like magnesium, and other life-giving elements like phosphorus and nitrogen, unlike carbon, which they can simply make out of sunlight and thin air. Plants and trees needed to find someone who could get them these basic elements due to their inherent lack of mobility. Fungi was the answer. They were able to transport nutrients back and forth between trees thanks to fungal networks that stretched for miles. In exchange, the fungus could eat the valuable carbon that the tree absorbed into its body – up to twenty tons over the course of a large tree’s lifetime. It was a classic case of symbiosis, a term coined by Albert Frank, a German botanist who also coined the term mycorrhiza.
