Russula
Definition
Noun: 1. A type of mushroom: A large genus of fungi characterized by stout stems, white spores, and brittle caps that can be various colors (red, purple, yellow, green, or blue). A key distinguishing feature is the absence of both an annulus (ring) and a volva (cup) at the base, and they do not exude a milky latex when damaged.
Examples of Usage
- Noun:
- The forest floor was dotted with the bright red caps of a russula.
- Many russula species are difficult to identify without microscopic examination.
- While some russula mushrooms are edible, others can cause gastrointestinal distress.
Advanced Usage
- In mycology: The term is used precisely to classify fungi within the genus , which contains hundreds of species. It is often contrasted with the closely related genus (milk-caps).
- The forager carefully noted the brittle gills and lack of latex to confirm it was a russula, not a Lactarius.
Variants and Related Words
- Russulaceae (n): The biological family to which the genus belongs.
- Brittlegill (n): A common English name for mushrooms in the genus, referring to the fragile nature of their gills.
Synonyms
- Brittlegill: This is a direct synonym, being the common name for the genus.
- Agaric (in a broad sense): As russulas are gilled mushrooms, they fall under the general category of agarics, though this term is much less specific.
