Reference excerpt

Inocybe corydalina var. corydalina, commonly known as the greenflush fibrecap, is a member of the genus Inocybe which is widely distributed in temperate forests. It is a small mycorrhizal mushroom which contains a small amount of the hallucinogen psilocybin.

Description Cap: 3.5–5 cm diameter, buff to brown, often with greenish tones, conic to convex or plane in age, with or without an umbo, with appressed fibrillose squamules on the cap which are more frequent towards the center, and an incurved margin. The center of the cap is darker brown to greenish, sometimes black and the flesh is white. Gills: adnate and very numerous, pale cream brown to grayish buff. Spores: Smooth and lemon shaped, measuring 8 x 5.5 micrometres, dull brown, often with a bluish-grayish stem base. Stipe: 2.5–10 cm long, 4 to 6 mm thick, and is equal width for the whole length, sometimes with some swelling at the base. The upper part of the stem is smooth and the lower part is fibrillose. Has a cortinate partial veil which soon disappears. Taste: Odor: Aromatic. Microscopic features: Pleurocystidia 33-70 by 9-21 micrometers, clavate cylindrical. Cheilocystidia are not common and look like pleurocystidia.

Distribution and habitat Inocybe corydalina var. corydalina is widespread across Europe and the British Isles. It usually fruits in the fall under deciduous trees but can also be found under conifers.

Edibility Gurevich and Nezoiminogo reported that this mushroom contains the mycotoxin muscarine but no psilocybin; other researchers have been unable to confirm this result. Chemical analysis by Stijve and Kuyper shows that it contains 0.032% psilocybin, a very low concentration.

Worked examples

Example 1 — a first encounter with Inocybe corydalina var. corydalina

Start with the simplest possible case. Write down what Inocybe corydalina var. corydalina claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 corydalina var. corydalina 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 corydalina var. corydalina 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 corydalina var. corydalina

In research: Inocybe corydalina var. corydalina appears in science 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 corydalina var. corydalina 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 corydalina var. corydalina is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fungi of Europe, Fungi of North America, Inocybe, so understanding it makes those chapters shorter.
In everyday life: Look for Inocybe corydalina var. corydalina 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.
