Gliophorus psittacinus

Gliophorus psittacinus 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 Gliophorus psittacinus rather than just read about it. In short: Gliophorus psittacinus, commonly known as the parrot toadstool or parrot waxcap, is a colourful mushroom that is a member of the genus Gliophorus. It was formerly known as Hygrocybe psittacina, but a molecular phylogenetics study found it to belong in the genus Gliophorus.

Key takeaways

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

Reference excerpt

Gliophorus psittacinus, commonly known as the parrot toadstool or parrot waxcap, is a colourful mushroom that is a member of the genus Gliophorus. It was formerly known as Hygrocybe psittacina, but a molecular phylogenetics study found it to belong in the genus Gliophorus. It had already been placed in Gliophorus, but it had been considered a synonym of Hygrocybe. It has a cosmopolitan distribution.

Description

The parrot toadstool is a small mushroom, with a convex to umbonate cap up to 4 centimetres (1.6 in) in diameter, which is green when young and later yellowish or even pinkish tinged. The stipe, measuring 2–8 cm (0.8–3.1 in) in length and 3–5 mm in width, is green to greenish yellow. The broad adnate gills are greenish with yellow edges and spore print white. The green colouring persists at the stem apex even in old specimens. The spores are white, elliptical, smooth and inamyloid. The spore print is white. Its odour and taste are mild. There are no known chemical tests. It fruits late summer to autumn (September to November).

Similar species It can resemble other species of its genus and Bolbitius callistus.

Distribution and habitat Gliophorus psittacinus is widely distributed in grasslands in western Europe, United Kingdom, Iceland, Greenland, North America, Americas, South Africa, Japan, being found in late summer and autumn. Early Australian records of this form have been found to be the similar green toadstools Gliophorus graminicolor or G. viridis on reexamination. Gliophorus psittacinus is known to occur at one site in the Lane Cove River valley near Sydney.

Conservation In Europe it is apparently in decline due to the degradation of habitats.

Edibility Gliophorus psittacinus is generally considered edible, but not worthwhile due to its small size and sliminess.

Worked examples

Example 1 — a first encounter with Gliophorus psittacinus

Start with the simplest possible case. Write down what Gliophorus psittacinus 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 Gliophorus psittacinus 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 Gliophorus psittacinus 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 Gliophorus psittacinus

In research: Gliophorus psittacinus 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 Gliophorus psittacinus 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: Gliophorus psittacinus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Edible fungi, Fungi described in 1774, Fungi of Africa, so understanding it makes those chapters shorter.
In everyday life: Look for Gliophorus psittacinus 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.
