Leavened bread
S. cerevisiae releases CO2 that lifts gluten. Wild sourdough adds lactic bacteria beside the yeast.
Darker cells mean a higher score for this topic on that metric.

Quick answers
Where should I start with Fungi?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Fungi?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Tree of microbes before English norms look universal.
Are the scores a ranking of Fungi?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Fungi to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
A kitchen already runs fungal factories: risen dough, soy sauce koji, blue cheese. The same kingdom includes athlete's foot and the oak-killing sudden oak death-adjacent stories in forests.
Chasing zero mould in a living house fights physics. Control moisture; target high-risk rooms; leave forest soils unsterilised on purpose.
Everyday uses
Koji and soy
Aspergillus oryzae builds koji for soy sauce, miso and some rice wines — East Asian domestication of a mould.
Compost networks
Saprotrophic fungi unlock lignin and cellulose. A sterile heap stays a pile of sticks.
Indoor damp
Black-stained bathrooms are often Cladosporium or similar. Fix leaks before buying a stronger scent.
Mushroom markets
Button, shiitake and oyster mushrooms are farmed fruiting bodies. Wild picking needs local expertise this page cannot supply.
Antibiotics origin story
The penicillin lineage began as a mould contaminant. Modern supply is industrial fermentation, not a windowsill protocol.
Respect water, wood and time — that is where unwanted indoor growth actually happens.

Packets of DNA or RNA that are not cells — they replicate only inside living hosts.
Familiarity 96Archaea
A prokaryotic domain that is not bacteria — methanogens, extremophiles and no known human pathogens.
Familiarity 35Bacteriophages
Viruses that infect bacteria — Earth's most abundant biological entities, and a concept-level idea in medicine.

Motile unicellular eukaryotes — a teaching grade that includes pond ciliates and a minority of serious parasites.
