Psilocybe guilartensis

Psilocybe guilartensis 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 Psilocybe guilartensis rather than just read about it. In short: Psilocybe guilartensis is a psilocybin mushroom which has psilocybin and psilocin as main active compounds. It is common in Puerto Rico.

Key takeaways

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

Reference excerpt

Psilocybe guilartensis is a psilocybin mushroom which has psilocybin and psilocin as main active compounds. It is common in Puerto Rico. First reported in the literature in 1997, Gastón Guzmán placed P. guilartensis in Psilocybe section Brunneocystidiatae due to its blue staining reaction, small thick-walled subrhomboid spores, and pigmented cystidia. Other mushrooms in the section Brunneocystidiatae include Psilocybe banderillensis, Psilocybe banderillensis var. paulensis, Psilocybe brunneocystidia, Psilocybe heimii, Psilocybe inconspicua, Psilocybe pleurocystidiosa, Psilocybe rzedowski, Psilocybe singeri, Psilocybe uxpanapensis, Psilocybe verae-crucis and Psilocybe weldenii.

Description Cap: 1 – 3 cm in diameter, initially subconical to campanulate (bell-shaped), expanding to plano-convex with an umbo. Cap surface dark violet brown in color, translucent-striate near the margin, hygrophanous, fading to tan as it dries. Staining blue-green to black where bruised. Gills: Cream color when young, violet brown or chocolate brown in age, with adnexed attachment. Spores: Dark violet brown, subrhomboid in face view, subellipsoid in side view, thick walled, 6 x 5 μm. Stipe: 3 – 8 cm long, 1 – 2 mm thick, central, equal with subbulbous base, hollow and cylindric, color whitish to brown, ornamented with small flattened scales towards the base. The base is covered in tiny yellow fibers which help distinguish this from similar species. Staining blue-green to black where bruised. Taste: Farinaceous, sometimes with a slight mustard taste. Odor: Farinaceous, sometimes with a slight mustard odor. Microscopic features: Pigmented cheilocystidia and pleurocystidia present. Basidia four-spored. Clamp connections common.

Distribution and habitat Psilocybe guilartensis is found growing gregariously, often on disturbed bare clay or moss. It is found along hiking trails, in coffee plantations, tropical and subtropical forests, especially in landslide areas. The mushroom is known to grow in Puerto Rico and Dominican Republic.

Worked examples

Example 1 — a first encounter with Psilocybe guilartensis

Start with the simplest possible case. Write down what Psilocybe guilartensis 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 Psilocybe guilartensis 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 guilartensis 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 guilartensis

In research: Psilocybe guilartensis 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 Psilocybe guilartensis 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 guilartensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Entheogens, Fungus species, Psilocybe, so understanding it makes those chapters shorter.
In everyday life: Look for Psilocybe guilartensis 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.
