Tricholoma pessundatum

Tricholoma pessundatum 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 Tricholoma pessundatum rather than just read about it. In short: Tricholoma pessundatum is a mushroom of the agaric genus Tricholoma. Taxonomy First described as Agaricus pessundatus by Elias Magnus Fries in 1821, it was transferred to the genus Tricholoma by Lucien Quélet in 1872.

Key takeaways

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

Reference excerpt

Tricholoma pessundatum is a mushroom of the agaric genus Tricholoma.

Taxonomy First described as Agaricus pessundatus by Elias Magnus Fries in 1821, it was transferred to the genus Tricholoma by Lucien Quélet in 1872.

Description The orangish cap is up to 18 centimetres (7 in) across, with a lighter margin, and is viscid when wet. The gills are white but develop stains and vary in attachment. The stem is up to 14 cm (5+1⁄2 in) long. The spore print is white. It has a sour meal odor.

Similar species A very similar species to the European mushroom is Tricholoma muricatum, which differs only in microscopic details.

Toxicity It contains toxins which can cause severe gastrointestinal upset.

Worked examples

Example 1 — a first encounter with Tricholoma pessundatum

Start with the simplest possible case. Write down what Tricholoma pessundatum 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 Tricholoma pessundatum 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 Tricholoma pessundatum 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 Tricholoma pessundatum

In research: Tricholoma pessundatum 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 Tricholoma pessundatum 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: Tricholoma pessundatum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fungi described in 1821, Fungi of North America, Fungus species, so understanding it makes those chapters shorter.
In everyday life: Look for Tricholoma pessundatum 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.
