Gymnopilus braendlei

Gymnopilus braendlei 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 Gymnopilus braendlei rather than just read about it. In short: Gymnopilus braendlei is a species of agaric fungus in the family Hymenogastraceae that contains the hallucinogens psilocybin and psilocin. It was originally described by mycologist Charles Horton Peck as Flammula braendlei, from specimens found in the District of Columbia in 1902.

Key takeaways

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

Reference excerpt

Gymnopilus braendlei is a species of agaric fungus in the family Hymenogastraceae that contains the hallucinogens psilocybin and psilocin. It was originally described by mycologist Charles Horton Peck as Flammula braendlei, from specimens found in the District of Columbia in 1902.

Description Pileus: 2.5–5 cm, hemispheric becoming convex, sometimes slightly umbilicate, hygrophanous, purplish when young then pinkish and lighter towards the margin, becoming yellowish in age with greenish stains, fibrillose, sometimes squamulose toward the center, flesh whitish, thin, staining greenish. Gills: Adnate, sometimes slightly sinuate in attachment, broad, close, whitish when young, becoming bright orangish brown to mustard yellow, becoming bright orangish brown in age. Spore print: Orangish brown. Stipe: 2.5–4 cm x 3–4 cm thick, more or less equal, pallid, sometimes yellowish at the base, fibrillose above, stuffed or hollow, veil fibrillose, sometimes leaving a silky zone but not forming an annulus. Taste: Bitter Microscopic features: Spores 6 x 8.5 x 4.5—5 μm ellipsoid to ovoid in face view, dextrinoid, verruculose, no germ pore. Pleurocystidia 22—33 x 6—7 μm, cheilocystidia 20—34 x 3—7 μm, no caulocystidia, clamp connections present. Bruising: Green or blue bruising at the base or on the pileus, and green spots on pileus likely.

Distribution and habitat Gymnopilus braendlei is found growing solitary or cespitose on tree stumps from June to November. It is widespread in the eastern U.S, and present in the western U.S.

Worked examples

Example 1 — a first encounter with Gymnopilus braendlei

Start with the simplest possible case. Write down what Gymnopilus braendlei 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 Gymnopilus braendlei 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 Gymnopilus braendlei 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 Gymnopilus braendlei

In research: Gymnopilus braendlei 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 Gymnopilus braendlei 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: Gymnopilus braendlei is common in secondary-school and first-year university syllabi. It links to neighbouring topics Entheogens, Fungi described in 1904, Fungi of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Gymnopilus braendlei 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.
