Periglandula clandestina

Periglandula clandestina 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 Periglandula clandestina rather than just read about it. In short: Periglandula clandestina is a fungus of the genus Periglandula. It is symbiotic with the morning glory plant Ipomoea tricolor (the Mexican morning glory).

Key takeaways

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

Reference excerpt

Periglandula clandestina is a fungus of the genus Periglandula. It is symbiotic with the morning glory plant Ipomoea tricolor (the Mexican morning glory). Ipomoea tricolor seeds are hallucinogenic in humans due to the presence of naturally occurring lysergamides or ergot alkaloids like ergine (lysergic acid amide; LSA) and isoergine (isolysergic acid amide; iso-LSA). The lysergamides present in Ipomoea tricolor are produced by Periglandula clandestina that it is symbiotic with rather than by Ipomoea tricolor itself. Periglandula clandestina, isolated from Ipomoea tricolor, was discovered and first described by Corinne Hazel and Daniel Panaccione at West Virginia University in 2025. P. clandestina was quantified most abundantly in hypocotyls of I. tricolor, with lesser quantities in stems, cotyledons, and leaves. The fungus was not detected in roots, although ergot alkaloids were abundant in all tissues including roots. In each tissue, LAH was the most abundant alkaloid (77% of the measured ergot alkaloids), followed in abundance by ergine and ergonovine. Apart from roots, tissues that had relatively high fungal DNA values also had relatively high ergot alkaloid value

Worked examples

Example 1 — a first encounter with Periglandula clandestina

Start with the simplest possible case. Write down what Periglandula clandestina 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 Periglandula clandestina 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 Periglandula clandestina 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 Periglandula clandestina

In research: Periglandula clandestina 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 Periglandula clandestina 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: Periglandula clandestina is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clavicipitaceae, Fungi described in 2025, Fungus species, so understanding it makes those chapters shorter.
In everyday life: Look for Periglandula clandestina 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.
