Mushrooms Are Not in the Bible — but Mould Is, in Leviticus

Mushrooms are not in the Bible. No Hebrew or Greek word in Scripture names a fungus of any kind, and the absence is more interesting than it sounds.

Scripture names a great deal of the natural world — dozens of plants, trees, birds, animals and insects, often in lists precise enough that translators still argue over individual entries.

Fungi are absent from all of it. There is no edible mushroom, no poisonous one, no truffle.

The likely reason is simply diet and geography. The region’s food culture was built on grain, pulses, olives, figs, dates and fish, and wild fungi did not have the place in it that they held further north.

Leviticus deals at length with something that behaves like a fungus, and it is not treated as food.

Chapters 13 and 14 cover a condition affecting people, fabrics and the walls of houses. The Hebrew term is the same in each case, usually translated “defiling mould” or “mildew” for the fabric and the house.

The house procedure is unexpectedly practical. The owner reports it, the priest inspects, the house is closed for seven days, affected stones are removed and replaced, the walls are scraped and the scrapings dumped outside the town. If it returns, the house is demolished.

Whatever the underlying biology, the response is quarantine, remediation and, failing that, removal — which is not a bad protocol for a growth in a wall.

The suggestion turns up periodically that manna was a fungus. The text does not support it.

The people of Israel called the bread manna. It was white like coriander seed and tasted like wafers made with honey. (Exodus 16:31)

Numbers adds that it could be ground in a mill or crushed in a mortar, boiled and made into cakes, and tasted like something made with olive oil (Numbers 11:8).

That is described as a grain-like substance, and it is handled like one.

The name itself is a question. When they first saw it they said man hu — what is it? — for they did not know what it was (Exodus 16:15). The thing is named after the fact that nobody could identify it, which is a detail worth more than any of the modern identifications.

There is a body of writing proposing that biblical or early Christian experience was driven by psychoactive fungi. It surfaces periodically and has never found support among scholars of the texts or the period.

The honest summary is that it rests on speculative etymologies and on reading imagery as pharmacology. No manuscript, no archaeological find and no ancient witness supports it.

Saying so is not defensiveness. It is the same standard applied to any claim about the ancient world: what is the evidence, and does it carry the weight.

It is a small reminder about how to read Scripture.

The Bible is a collection of documents written by particular people in a particular place, who wrote about what was in front of them. They named the plants they ate and the birds they saw. Where something is missing, the usual reason is that it was not there.

That is not a limitation to be apologised for. A book that mentioned everything would be a book from nowhere.

Are mushrooms mentioned in the Bible?

No. No Hebrew or Greek word in Scripture names a fungus.

Why not?

Most likely diet and geography. The region’s food culture was built on grain, pulses, olives, figs, dates and fish.

Is mould in the Bible?

Yes. Leviticus 13-14 covers a defiling growth in fabrics and house walls, with a procedure of inspection, closure, removal of stones, scraping and — if it returns — demolition.

Was manna a mushroom?

The text describes something grain-like: white as coriander seed, tasting of honey wafers, ground in a mill and made into cakes. The name means “what is it?”
