Neoboletus venenatus

Neoboletus venenatus 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 Neoboletus venenatus rather than just read about it. In short: Neoboletus venenatus, known until 2015 as Boletus venenatus, is a species of bolete fungus in the family Boletaceae native to Japan and China. It was transferred to the new genus Neoboletus by Chinese mycologists Gang Wu and Zhu L.

Key takeaways

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

Reference excerpt

Neoboletus venenatus, known until 2015 as Boletus venenatus, is a species of bolete fungus in the family Boletaceae native to Japan and China. It was transferred to the new genus Neoboletus by Chinese mycologists Gang Wu and Zhu L. Yang in 2015.

Taxonomy Japanese mycologist Eiji Nagasawa described this species as Boletus venenatus in 1995. It is known in Japan as dokuyamadori or tahei-iguchi.

Description The cap is dome-shaped initially, then convex to cushion-shaped, before flattening out in maturity, attaining diameters of 7–26 cm (2.8–10.2 in), and can be various shades of yellow-grey, olvie-brown or yellow-brown. The surface is dry and slightly furry when young, and the cap margin curved inwards. The pale yellow flesh is 2–3 cm (0.79–1.18 in) thick under the cap and slowly turns pale blue on bruising. The pores are yellow to yellow-brown and stain dark blue quickly upon bruising. Covered in fine scales, the stipe is yellow-brown fading to pale yellow at the top, measuring 10–15 cm (3.9–5.9 in) tall by 2–4.5 cm (0.79–1.77 in) wide. It also stains pale blue on bruising. The mycelium is pale yellow.

Distribution and habitat Neoboletus venenatus has been found in southwestern China, specifically Laojun Mountain in Yulong County in Yunnan province and Kangding County in Sichuan province, and Japan, specifically Hokkaido and central Honshu. It grows in subalpine regions. associated with conifers such as Abies, Picea and Tsuga.

Toxicity Neoboletus venenatus is poisonous, causing severe gastrointestinal symptoms of nausea and recurrent vomiting, which can be severe enough to result in dehydration. Symptoms generally resolve in a few days. One toxic compound—bolevenine—was isolated and described by Matsuura and colleagues in 2007.

Worked examples

Example 1 — a first encounter with Neoboletus venenatus

Start with the simplest possible case. Write down what Neoboletus venenatus 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 Neoboletus venenatus 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 Neoboletus venenatus 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 Neoboletus venenatus

In research: Neoboletus venenatus 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 Neoboletus venenatus 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: Neoboletus venenatus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fungi described in 1996, Fungi of China, Fungi of Japan, so understanding it makes those chapters shorter.
In everyday life: Look for Neoboletus venenatus 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.
