Unique, remarkably diverse and essential to life on Earth, fungi form an entire biological kingdom. Scientists estimate that between 2.2 and 3.8 million fungal species may exist worldwide, although most have yet to be formally identified.
Fungi are found almost everywhere. Mushrooms rise from damp forest floors, mould spreads across food and decaying material, and microscopic yeasts ferment sugars as bread dough rises.
Unlike plants, fungi cannot produce energy from sunlight. Instead, they release digestive enzymes into their surroundings. These enzymes break complex organic materials into smaller substances that the fungus absorbs for energy and growth. This distinctive feeding method makes fungi important recyclers in ecosystems around the world.
Explore the kingdom of fungi through three broad groups: basidiomycetes, moulds and yeasts.
BASIDIOMYCETES
Basidiomycetes include mushrooms, puffballs and bracket fungi. Their name comes from the basidium, a microscopic, club-shaped structure on which spores are produced.
In a typical cap-and-stem mushroom, millions of spores develop beneath the cap, often along thin structures called gills. The gills provide a large surface area for spore production. Mature spores are released and carried away by air currents. If one reaches a place with suitable moisture, temperature and nutrients, it may begin to grow.
The mushroom above the ground is only the reproductive fruiting body of a larger organism. Most of the fungus remains hidden in soil or wood as microscopic threads called hyphae. Together, these threads form a spreading network known as a mycelium.
Not all basidiomycetes resemble ordinary mushrooms. Bracket fungi form tough, shelf-like structures on tree trunks and fallen logs. Tiny pores on their undersides are lined with basidia that produce and release spores.
Puffballs disperse spores more dramatically. As a puffball matures, its interior fills with millions of powder-like spores. A raindrop, passing animal or gentle touch can compress it, forcing a visible spore cloud through an opening at the top. Wind carries the spores to new locations.
Many basidiomycetes decompose dead wood and leaf litter, returning nutrients such as nitrogen and phosphorus to the soil. Without decomposers, dead material would accumulate and nutrients would remain unavailable to other organisms.
Others form partnerships with plant roots called mycorrhizae. The fungus helps the plant absorb water and minerals, while the plant supplies sugars produced through photosynthesis. These mutually beneficial relationships support plant growth and healthy forests.
MOULDS
Moulds often appear as fuzzy, spreading colonies on food, soil and other organic materials. Their bodies consist of branching hyphae that form a mycelium. Reproductive, spore-containing structures arise from this feeding network.
Bread mould, or Rhizopus, is a common example. Penicillium may appear as blue or green patches on bread and fruit. Some Penicillium species produce the antibiotic penicillin, while others help create the colours, textures and flavours of certain cheeses.
Moulds release enormous numbers of lightweight spores. These travel through the air and begin growing when they land somewhere with suitable moisture, nutrients and temperature. New hyphae spread through the material, releasing digestive enzymes and absorbing nutrients.
Although many moulds are harmless or useful, others spoil food, damage buildings or cause disease. Mould spores may irritate the eyes, skin and respiratory system, particularly in people with allergies, asthma or weakened immune systems. Visible mould in human environments should be treated carefully.
YEASTS
Unlike most fungi, yeasts are unicellular, meaning each organism usually consists of one cell. Many reproduce through budding: a small outgrowth forms on a parent cell, enlarges and eventually separates.
Yeasts are important to humans because of fermentation. In baking, yeast consumes sugars and releases carbon dioxide. Gas becomes trapped in the dough as bubbles, causing it to expand and rise. In brewing and winemaking, yeasts ferment sugars to produce alcohol. Humans have used these processes for thousands of years.
WHY FUNGI MATTER
Fungi connect many parts of the living world. They decompose dead organisms, recycle nutrients, support plant roots, improve soil health and provide food for other organisms. Some fungi are eaten directly, while others help make bread, cheese and fermented drinks. Fungal compounds have also contributed to medicines and scientific research.
From colourful mushrooms and explosive puffballs to fuzzy mould colonies, microscopic yeasts and hidden mycelial networks, fungi take many forms. Whether recycling dead material, supporting plant growth, producing medicines or helping us make food, fungi are essential to ecosystems and human life.
