Clavaria vermicularis, commonly known as White Spindles or White Worm Coral, is a species of coral fungus characterized by its unbranched, cylindrical to spindle-shaped, pure white fruiting bodies that grow in dense clusters. It is a saprobic fungus, playing a role in the decomposition of organic matter in grasslands and woodlands.
How to Identify
- Cap
- Not applicable, as Clavaria vermicularis is a coral fungus and does not possess a distinct cap.
- Gills
- Not applicable, as Clavaria vermicularis is a coral fungus and does not possess gills.
- Stem
- The fruiting body itself functions as the stem, arising directly from the substrate. It is concolorous with the rest of the fruiting body, pure white, and often slightly thicker at the base.
- Flesh
- The flesh is white, brittle, and watery. It has no distinctive odor or taste.
- Fruiting body
- The fruiting bodies are typically 2-10 cm tall and 2-5 mm thick, unbranched, cylindrical to spindle-shaped, often tapering slightly towards the apex. They are pure white, smooth, and often grow in dense clusters, sometimes appearing somewhat fused at the base. They are brittle and hollow or solid when young, becoming hollow with age.
- Habitat
- Typically found growing gregariously or in dense clusters on soil, often in grassy areas, lawns, pastures, and open woodlands. It prefers disturbed ground and nutrient-rich soils.
Key Facts
- Cap surfaces: Not applicable
- Growth Form: Gregarious to caespitose (in dense clusters)
- Spore Print: White
- Body color: Pure white
- Odor: Indistinct
- Flesh bruises: Does not bruise
- Height: 2-10 cm
- Cap Diameter: Not applicable
- Nutrient gathering: Saprobic
Safe
SafeClavaria vermicularis is generally considered edible, but its edibility is often described as 'poor' or 'insignificant' due to its bland taste, brittle texture, and small size. There are no known toxins associated with this species. However, caution is always advised when consuming wild mushrooms. Misidentification with other white coral fungi, some of which may cause mild gastrointestinal upset, is a possibility. Always cook wild mushrooms thoroughly.
Quick Check
- Odor: Indistinct
- Fruiting: Unbranched, pure white, cylindrical to spindle-shaped 'spindles' growing in clusters.
- Substrate: Soil, grass, moss, often in disturbed areas.
Where to Find
North America
Widespread across temperate regions, particularly in eastern North America.
Europe
Common throughout Europe, especially in grasslands and open deciduous or coniferous forests.
Asia
Reported in parts of Asia, though less extensively documented than in Europe and North America.
Australia
Found in suitable habitats in Australia.
Finding Tips
Seasonality
Primarily found from late summer through autumn, sometimes extending into early winter in milder climates.
Habitat Preference
Look for it in short grass, mossy areas, lawns, pastures, and along woodland edges. It often appears after periods of rain.
Growth Pattern
It typically grows in dense clusters, making it easier to spot. Individual 'spindles' are rarely found alone.
