Panaeolus cambodginiensis

Panaeolus cambodginiensis 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 Panaeolus cambodginiensis rather than just read about it. In short: Panaeolus cambodginiensis is a hallucinogenic mushroom that contains psilocybin and psilocin. It was described in 1979 as Copelandia cambodginiensis.

Key takeaways

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

Reference excerpt

Panaeolus cambodginiensis is a hallucinogenic mushroom that contains psilocybin and psilocin. It was described in 1979 as Copelandia cambodginiensis.

Description The cap is less than 23 mm across, with a convex shape and an incurved margin when young, expanding to broadly convex. The cap surface is smooth, often cracking with irregular fissures. The gills are gray to black. The stem is 5 to 10 centimetres (2.0 to 3.9 in) tall, 4 mm thick, and slightly swollen at the base. The spores are black, shaped like lemons, smooth, measuring 11 x 8 μm. The entire mushroom quickly bruises blue where it is handled. It can be differentiated from the similar Panaeolus cyanescens by microscopic characteristics.

Distribution and habitat Panaeolus cambodginiensis is mushroom that grows on the dung of water buffalo and other ruminants. It was first described from Cambodia and is widespread throughout the Asian subtropics and Hawaii.

Alkaloid content A srongly bluing species, Merlin and Allen (1993) reported the presence of psilocybin and psilocin, up to .55% and .6%, respectively.

Worked examples

Example 1 — a first encounter with Panaeolus cambodginiensis

Start with the simplest possible case. Write down what Panaeolus cambodginiensis 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 Panaeolus cambodginiensis 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 Panaeolus cambodginiensis 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 Panaeolus cambodginiensis

In research: Panaeolus cambodginiensis 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 Panaeolus cambodginiensis 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: Panaeolus cambodginiensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fungi of Asia, Fungi of Hawaii, Fungi of Oceania, so understanding it makes those chapters shorter.
In everyday life: Look for Panaeolus cambodginiensis 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.
