Phellodon tomentosus

Phellodon tomentosus 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 Phellodon tomentosus rather than just read about it. In short: Phellodon tomentosus, commonly known as the zoned phellodon or zoned cork hydnum, is a species of tooth fungus in the family Bankeraceae. First described as Hydnum tomentosum by Carl Linnaeus in 1753, it was transferred to the genus Phellodon by Howard James Banker in 1906.

Key takeaways

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

Reference excerpt

Phellodon tomentosus, commonly known as the zoned phellodon or zoned cork hydnum, is a species of tooth fungus in the family Bankeraceae. First described as Hydnum tomentosum by Carl Linnaeus in 1753, it was transferred to the genus Phellodon by Howard James Banker in 1906. The brown cap is 1.5–5 cm wide, broad, flat, or funnel-shaped, sometimes fused with others, zoned with a white margin, dry, thin, and fragrant-smelling; the taste is mild to bitter. The spines on the undersurface are 1–3 mm long, grayish-brown with pale tips, some running down the upper portion of the stalk. The flesh is brown. The stalk is 1–5 cm tall and 2–5 mm wide. The spores are white and more or less globose and spiny. Similar species include Phellodon atratus, Coltricia cinnamomea, Sarcodon fuscoindicus. The mushroom is found in Asia, Europe, and North America. It is inedible.

Worked examples

Example 1 — a first encounter with Phellodon tomentosus

Start with the simplest possible case. Write down what Phellodon tomentosus 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 Phellodon tomentosus 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 Phellodon tomentosus 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 Phellodon tomentosus

In research: Phellodon tomentosus 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 Phellodon tomentosus 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: Phellodon tomentosus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agaricomycetes stubs, Fungal taxa named by Carl Linnaeus, Fungi described in 1753, so understanding it makes those chapters shorter.
In everyday life: Look for Phellodon tomentosus 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.
