Mushroom (pronounced muhsh-room)
(1) Any of
various fleshy fungi including the toadstools, puffballs, coral fungi, morels
etc; any of several edible species, especially of the family Agaricaceae, as
Agaricus campestris meadow mushroom, or field mushroom, cultivated for food in many
places.
(2) A
fungus producing such fruiting bodies.
(3) Anything
of similar shape or correspondingly rapid growth.
(4) As ellipsis
of “mushroom cloud”, a large, mushroom-shaped cloud of smoke or rubble, formed
in the atmosphere as a result of an explosion (or other sudden release of
energy), especially a nuclear explosion.
(5) Of,
consisting of, or containing mushrooms.
(6) Resembling
a mushroom in shape or form; to have or assume the shape of a mushroom.
(7) Of
rapid growth and often brief duration (to spread, grow, or develop quickly).
(8) To
gather mushrooms (typically as “mushrooming”, practiced by a mushroomer).
(9) As “magic
mushroom” (used typically in the plural), any mushroomlike fungus that after
ingestion induces psychedelic effects (“shrooms” to users, “psilocybin mushroom”
to clinicians in some jurisdictions where prescription is now lawful).
(10) In ballistics
(of a bullet), to form the shape of a mushroom when striking a soft target.
(11) In bar
billiards, any of the mushroom-shaped pegs.
(12) In architecture,
a concrete column with a thickened portion at the top, used to support a slab.
(13) In
slang, an individual who rises rapidly from obscurity or poverty (now rare and
displaced by “upstart”); the figurative sense of something that grows very
quickly or seems to appear suddenly remains in use.
1350–1400: Following
the usual conventions in English, it may be expected the construct was mush- +
-room but those words wholly are unrelated and the ultimate source is unknown. Mushroom was an alteration (by folk
etymology) of the Middle English muscheron
& musseroun, from the eleventh
century Middle French mousseron, from
the Anglo-Norman musherum & moscheron, from the Old French moisseron, from the Late Latin mussiriōn- (stem of mussiriō). The Old French
word had a murky history and etymologists suspect it was from the Old French mosse & moise (moss (from which modern French gained mousse (on the basis of the first known use being of a type of
fungus which grows in moss))), from the Frankish mosu (moss) or the Old Dutch mosa
(moss). The Old French was akin to the Old
High German mosa (moor, swamp), the Old
High German mos (moss, bog) & mios (moss, mire), the Old English mēos (moss) & mōs (bog, marsh), the Old Norse mosi
(moss) & myrr (bog, mire), all
from the Proto-Germanic musą, muso & miuziz (mosses, bog), from the primitive Indo- European mews- (mosses, mold, mildew). It displaced the native Old English swamm.
The clipping shroom is a synonym (most popular with users of magic
mushrooms) and the spelling mushrump is
long obsolete (the modern spelling more or less standardized by the
1560s). Mushroom is a noun, adjective
& verb, mushroomed is a verb, mushrooming is a noun & verb, mushroomer
is a noun, mushroomic, mushroomless, mushroomlike, mushroomoid & mushroomy
are adjectives; the noun plural is mushrooms.
Ingredients
3 tablespoons olive oil or butter
3 cups thinly sliced baby portabella mushrooms or white button mushrooms
½ cup finely chopped onion
1-2 cloves garlic, minced
3 tablespoons all-purpose flour or cup for cup gluten-free flour
3 cups beef broth/stock or vegetable stock
Salt and pepper to taste
Instructions
(1) In a large skillet, heat oil over medium-high heat. Sautee mushrooms and onions until they are nicely browned (should take around 7 minutes). Add in garlic and stir until fragrant (about 30 seconds).
(2) Stir in the flour and cook for 1 minute. Whisk in the broth, remembering to scrape from the bottom of pan all the "browned bits" (the best part). Reduce to a simmer and simmer until thickened, then remove from heat. Taste for salt and pepper and season to taste.
The alternative etymology (noting the Ancient Greek μύκης (múkēs) (mushroom) suggests the Old French may be of pre-Roman origin and it remains a matter of debate among etymologists (almost all lexicographers stick to “of uncertain origin”). What is agreed is the noun “mushroom” was at first applied to almost any of the larger fungi but later to the agaricoid fungi (especially the edible varieties). The figurative use for something or someone that makes a sudden appearance in full form dates from the 1590s; it was applied especially an upstart person (bounder) or family (those who rose rapidly from a low station in life). All that was based on the mushroom’s impressively rapid rate of growth and by the 1740s the figurative use substantially has lost the “upstart” sense and came to be used generally of “expanding or increasing rapidly; to rise suddenly in position or rank”. The famous (or infamous) “mushroom cloud” was first widely described in 1916 (World War I (1914-1918) a time & place of big explosions witnessed by many with cameras) but the OED (Oxford English Dictionary) cites the first use as dating from US in 1902. It thus long pre-dates the nuclear-age but the phenomenon would for millennia (long before there were explosives) have been observed by those watching volcanic eruptions. After photographs of the immediate aftermath of the A-bombing of Hiroshima & Nagasaki (August 1945) widely were publicized, the term became popular and spread to many aspects of popular culture including film, art and T-shirts.
Germania,
Berlin’s sandy soil and the “mushroom” used to test for sinkage
Until in the twenty-first century the CCP (Chinese Communist Party) began doing things at a scale once thought unsustainable, the urban-redevelopment plan imagined on a grandest scale was that for Berlin designed by Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945). What was the be the capital of the Third Reich (and, in the minds of the most delusional of the Nazis: “of the world”) would be renamed Germania and, as Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) told Speer’s wife: “Your husband is going to build buildings for me the likes of which haven't been built for 4,000 years.” Prone to lies and exaggeration, this was one of the occasions the Führer was being truthful and although there was little the plans for Germania that was original, what was impressive was the scale, Speer taking reference points from architectural history (the Pantheon in Rome, the Arc de Triomphe in Paris) and making the German versions bigger. Although at the time much taken with what he called the regime’s “Empire style”, in his (sometimes reliable) post-war memoirs (Erinnerungen (Memories or Reminiscences) and published in English as Inside the Third Reich (1969)) he admitted the stylistic failure, above all because the architecture wholly was disconnected from the human scale.
Of all that
Speer planned for Hitler's megalomaniacal vision of Germania, only small
fragments remain but the strangest and largest relic is the Schwerbelastungskörper (heavy
load-bearing body) a concrete structure 30 metres (100 feet) tall and weighing
12,650 tons (11,476 tonnes); locals nicknamed it der Pilz (the mushroom).
Located on the city’s southern edge (near modern day Südkreuz station),
the giant concrete cylinder was in 1941 erected to test the suitability of
Berlin’s sandy soil, something of great significance because most of Germania’s
large, representational buildings would be constructed from granite, concrete
& steel; although structural engineers could solve the challenges the
architects designs presented, the only way to be certain the soil could handle
such weight was to conduct a practical, real-time, full-size experiment. While the data were required for much of
what was planned, of particular interest was intended landmark of the Victory
Arch which, at 117 metres (384 feet) tall and 170 metres (558 feet) wide would
obviously exert much pressure and, having the foundations sinking into the sandy
soil was less than ideal. With a
footprint of exactly 100 m3, Speer’s giant, reinforced concrete
“mushroom” was placed in a way that would as closely as possible emulate the
forces involved; it sat 18 metres (60 feet) deep with the above-ground extending
14 metres (46 feet) high while inside there were a number of measuring devices
recording movement. As things transpired
the instruments recorded sinking between 110-180 mm (4.3-7.1 inches) across the
six measuring points and that was well beyond the 60 mm (2.4 inches) deemed by
Speer as the upper limit of acceptability.
Whether the findings would have compelled a change to the arch or indeed
any of Germania’s other gargantuan designs will never be known because, as the
tide of war turned, the resources devoted to the project were re-allocated to
more urgent tasks and by 1943 Speer, by then also minister of armaments and war
production, quietly shut-down the Germania planning office. So little was built and less survived but the
“mushroom” remained and is now a tourist attraction and a site visited by many
organized tours.
The
mushroom cloud
As the photographs suggest, the mushroom clouds generated by large volcanic eruptions and the detonation of nuclear weapons can look similar because the same atmospheric physics are operating despite the underlying energy-release mechanisms being completely different and, counterintuitively, there is no precise TNT (abbreviation of trinitrotoluene (an explosive substance used in blasting)) equivalent threshold above which every explosion produces a mushroom cloud. A mushroom cloud is principally a consequence of buoyancy and atmospheric fluid dynamics, rather than merely a product of energy released, thus the phenomenon can occur with nuclear explosions, large conventional explosions, volcanic eruptions and even especially intense fires. What an explosion does is produce a very hot, rapidly expanding mass of gas and entrained material and this rises because the air above has less resistance than the ground below; it rises because it has acquired enormous upward momentum and, as it rises, it entrains surrounding air. The most important mechanism in the ultimate generation of a mushroom cloud’s distinctive shape is a phenomenon plasma physicists call “thermal buoyancy”.
Physics of a mushroom cloud (left), the fluid dynamics an interplay of energy, matter & air temperature and a mushroom cloud T-shirt (right), the images used sometimes for political messaging and sometimes just for dramatic effect.
Familiar
from many conditions in climate science, as hot material rises, the heated gas being
less dense than the surrounding atmosphere, the rising plume entrains cooler
air, increasing its volume while reducing its average temperature, a process
that continues until its density approaches that of the surrounding atmosphere
at which point, the rising material spreads laterally, producing the mushroom
cloud’s characteristic “cap”, the outer regions circulating downwards, maintain
the shape of the stem. There are scaling relationships between explosion energy and the size,
height and evolution of the resulting plume and consequently, as a general
principle, as explosions become larger, a mushroom cloud becomes increasingly
likely under appropriate atmospheric conditions. So the mushroom cloud is a product of the
environment; the same release of energy in different conditions (an explosion
deep underground; a large underwater explosion; an explosion in a confined
structure; energy released over a sufficiently long period rather than
instantaneously) will tend not to create one whereas a relatively modest release
of energy can produce one if the geometry and atmospheric conditions are favourable. So, a mushroom cloud is a thing not of yield
but of atmospheric conditions.
In 2023,
Australian mother of two Erin Patterson (b 1974) murdered three of her relatives and nearly
killed a fourth by preparing for them a lunch of Beef Wellingtons laced with highly
toxic death cap mushrooms. Amanita
phalloides (the more evocative “death cap” the common name) is a basidiomycete
fungus and mushroom (one of many in the genus Amanita) and although originally
from Europe, it has spread around the planet as have many species (zoological &
botanical) in the age of mass-movement of people and goods. Dangerously, the death cap closely resembles a
number of (variously bland and delicious) edible mushrooms used in many dishes
so mushroomers must take care when mushrooming (harvesting wild mushrooms). They’re the most poisonous of all known
mushrooms and a single example contains enough toxin to kill an adult human;
unsurprisingly, death caps are estimated to be responsible for as many as 90%
of the annual death-toll from eating toxic mushrooms. Quite what is the extent of the annual loss
of life is uncertain because in rural parts of Asia (where foraged mushrooms
are common in diets) the statistics are not reliable but it’s believed the numbers
bounce-around between 100-300. The principal
toxic constituent (hardly affected by cooking or freezing) is α-Amanitin which
causes liver and kidney failure.
It was severe liver failure that was the cause of the death of Erin Patterson’s three victims, all of whom died within a week of falling ill (despite one receiving a liver transplant); the sole survivor recovered after several weeks of treatment. The trial was conducted before a jury that delivered a guilty verdict on all three charges and the judge handed down a sentence of life imprisonment with a non-parole period of 33 years; there was immense international interest in the case and it was the first sentencing hearing in the state of Victoria to be live-streamed. In what was anyway a macabre tale, one interesting aspect was the way Erin Patterson chose to learn about the nature of the death cap; some will have drawn the conclusion: “When researching murder-methods, don’t use one’s own digital devices.” The case currently is on appeal, the defense seeking a retrial on several procedural and technical grounds while the state is arguing the sentence was “manifestly inadequate” and there should be no possibility of parole. On X (formerly known as Twitter), some were even more unforgiving, suggesting: “She should get the chair.”
In her cell, “mushroom lady” (the public's choice of dub upon the case being publicized) is said to pass the hours crocheting, an intricate, time-consuming business but for those serving long prison sentences, time is relative in a way different to that made famous by Albert Einstein (1879-1955) and for the seven Nazis incarcerated in Spandau prison after the first Nuremberg Trial (1945-1946), “time” often came up in their sometimes awkward conversations. Grand Admiral Erich Raeder (1876–1960; head of the German Navy 1928-1943) served as prison librarian and, responding to a complaint from one of his fellow inmates that his handing out the four permitted (and by 1954 uncensored) newspapers (one selected by each of the powers administering the prison (France (Kurier), the UK (Frankfurter Allgemeine Zeitung), US (Die Welt) & USSR (Berliner Zeitung) bound in one folder meant “It will take too long for one person to read all four newspapers”, answered “That doesn't matter. You've got plenty of time, after all.” Despite that uncompromising start, within two days the admiral relented, averting the threat of mutiny by distributing the papers singularly.
One unexpected coda to the trial was the announcement mushroom lady has been granted access to taxpayer-funded Ozempic (a GLP-1 (glucagon-like peptide-1) appetite suppressant), the official explanation being her inability to pursue an exercise regime while in solitary confinement; because of the nature of her offences, it's expected she'll remain in solitary confinement for the foreseeable future (33 years presumably within the vista of “foreseeable”). Unfortunately, her previous exercise techniques were not disclosed, something that would have been of interest to many pursuing weight-loss. Doubtlessly anticipating some public outrage at the thought taxpayers would be footing the bill for mushroom lady to get free “fat jabs”, a spokesperson for Victoria’s Department of Justice issued a statement confirming weight loss drugs were just another medicine and would be provided to prisoners based on a clinician's advice: “Prescriptions are only given by clinicians when there’s a clear medical need - like preventing serious conditions such as type 2 diabetes. Access to prescribed weight loss medication was introduced in response to recommendations from the Coroner following a death in custody linked to obesity.” The convicted mass-murderer had told the court she “had a problem” with body image and binge-eating, a perhaps unnecessary confirmation given some of the photographs circulated by the media.
