Reference excerpt

Psilocybe liniformans var. americana, is a psilocybin mushroom in the family Hymenogastraceae. It is in the section Semilanceatae of Psilocybe and has psilocybin as its main active compound.

Description The cap is 1 — 2.5 cm convex to nearly plane, and is sometimes broadly umbonate but not papillate. It is smooth, dull grayish brown to slightly olivaceus, more reddish at the center, hygrophanous, and becoming straw brown when dry with the center remaining more brownish. It sometimes has a bluish green tone, or olivacous tones at the margin when young. The gills are adnexed, subdistant, broad, and dark chocolate brown to purplish brown with age. The spores are dark purple brown, ellipsoid, and 13 — 14.5 by 7.5 — 8.8(10)μm. The stipe is 1.4 — 3.0 cm by 1 – 2 mm, equal, enlarging at the base. It is whitish to very pale brownish, darker below, bruising blue, and finely fibrillose in the lower portion. The partial veil is thin and soon disappears. The taste is weak to somewhat farinaceous; The odor is strongly aromatic to farinaceous. Microscopic features: The basidia are 4-spored and pleurocystidia are absent. The cheilocystidia are 22 — 33 by 5.5 — 9 μm, lageniform and have an extended neck.

Habitat and formation Psilocybe liniformans var. americana is found scattered to gregarious in rich pastures or grasslands, fruiting from summer to early winter. It has been collected in Washington, Oregon, and Michigan, and has also been reported from Chile where it fruits in the spring. This mushroom is very close to the type variety; the main difference is the lack of a gelatinous layer on the edge of the lamellae and the terricolous habitat.

Worked examples

Example 1 — a first encounter with Psilocybe liniformans var. americana

Start with the simplest possible case. Write down what Psilocybe liniformans var. americana 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 Psilocybe liniformans var. americana 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 Psilocybe liniformans var. americana 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 Psilocybe liniformans var. americana

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