Inocybe aeruginascens

Inocybe aeruginascens is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Inocybe aeruginascens rather than just read about it. In short: Inocybe aeruginascens is a member of the genus Inocybe which is widely distributed in Europe. The species was first documented by I.

Key takeaways

Inocybe aeruginascens belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Inocybe aeruginascens to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Inocybe aeruginascens from memory before moving on to harder problems.

Reference excerpt

Inocybe aeruginascens is a member of the genus Inocybe which is widely distributed in Europe. The species was first documented by I. Ferencz in Ócsa, Hungary on June 15, 1965.

Description Inocybe aeruginascens is a small mycorrhizal mushroom with a conic to convex cap which becomes plane in age and is often fibrillose near the margin. It is usually less than 5 cm across, has a slightly darker blunt umbo and an incurved margin when young. The cap color varies from buff to light yellow brown, usually with greenish stains which disappear when the mushroom dries. The gills are adnate to nearly free, numerous, colored pale brown, grayish brown, or tobacco brown. The fruit body has greenish tones and bruises blue where damaged. The spores are smooth and ellipsoid, measuring 6–9.5 x 4.5 micrometres and forming a clay brown spore print. The stem is 2–7 cm long, 3 to 8 mm thick, and is equal width for the whole length, sometimes with some swelling at the base. It is solid, pale grey, becoming bluish green from the bottom up. The stem is fibrous and appears to be covered with fine powder near the top. It has a partial veil which often disappears in age and an unpleasant soapy odor.

Distribution and habitat Inocybe aeruginascens is widely distributed in temperate areas and has been reported in central Europe and western North America. It grows in moist sandy soils in a mycorrhizal relationship with poplar, linden, oak and willow trees.

Edibility No toxicology information exists on Inocybe aeruginascens currently, however a minimum of "23 unintentional intoxications" were reported in 1982 by Drewitz and Babos. Unintentional consumption could be due to the similarity of Marasmius oreades. The symptoms of "intoxication" were hallucinogenic, leading Gartz and Drewitz to eventually discover the first source of psilocybin in any Inocybe species. There are no known deaths directly related to consumption, however edibility is not yet conclusive.

Biochemistry Inocybe aeruginascens contains the formerly known alkaloids psilocybin, psilocin, baeocystin, as well a newly discovered indoleamine 4-phosphoryloxy-N,N,N-trimethyltryptamine. Jochen Gartz named this new substance aeruginascin after the mushroom species. Aeruginascin is the N-trimethyl analogue of psilocybin. Inocybe aeruginascens and Pholiotina cyanopus are the only known natural sources of aeruginascin.

Worked examples

Example 1 — a first encounter with Inocybe aeruginascens

Start with the simplest possible case. Write down what Inocybe aeruginascens claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Inocybe aeruginascens before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Inocybe aeruginascens ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Inocybe aeruginascens

In research: Inocybe aeruginascens appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Inocybe aeruginascens in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Inocybe aeruginascens is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fungi described in 1968, Fungi of Europe, Fungus species, so understanding it makes those chapters shorter.
In everyday life: Look for Inocybe aeruginascens outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
