4 Common Lawn Mushroom Species in the UK: Identify Garden Fungi
As a proud British homeowner, you've likely spent countless hours maintaining your beautiful garden. And while roses, daffodils, and neatly trimmed hedges are sure to grab attention, there's another group of organisms quietly claiming space in your garden – mushrooms. In this article, we'll explore four common lawn mushroom species found in the UK, providing you with the knowledge to identify and understand these fascinating garden fungi.
Background and Significance of Lawn Mushrooms
Mushrooms are the fruiting bodies of fungi, which play a vital role in breaking down organic matter and recycling nutrients in the soil. While mushrooms in your garden may not align with your aesthetic goals, their presence is essential for a healthy ecosystem. Here are four common mushroom species found in the UK:
1. Honey Fungus (Armillaria species)
Honey fungus is a perennial favourite among UK gardeners, recognised by its honey-coloured, slightly shiny cap and white gills. It tends to grow on trees or wooden structures and may appear in clusters. While honey fungus might look appealing, it can be quite detrimental to garden plants, particularly if unchecked.
- Cap: 3-15 cm, honey-coloured, and slightly shiny
- Gills: white, closely spaced
- Stipe (stem): 8-20 cm, cylindrical, and fibrous
2. Fairy Ring Champignon (Marasmius oreades)
Fairy ring champignons are named after their association with fairy rings – circular patterns of mushrooms believed to be enchanted by fairies. These small, buff-coloured mushrooms make for a captivating sight in any garden or grassy area. Although they may cause discolouration in the grass, fairy ring champignons are generally harmless and quite attractive.
- Cap: 2-5 cm, buff to pale tan, domed
- Gills: widely spaced, off-white or cream
- Stipe: 3-7 cm, cylindrical, and tough
3. Common Ink Cap (Coprinopsis atramentaria)
The common ink cap, also known as the inky cap or tippler’s bane, is a widespread mushroom species in the UK. It is called the "ink cap" due to its tendency to autodigest its cap, releasing a black, ink-like substance. The common ink cap is often found in disturbed habitats or on stumps, and while not particularly problematic, it's best to avoid consuming this mushroom, as it may cause adverse reactions when combined with alcohol.
- Cap: 3-6 cm, dark grey to grey-brown, conical to bell-shaped
- Gills: white initially, turn pinkish then black, and dissolve into ink
- Stipe: 5-12 cm, white, and hollow
4. The Stinkhorn (Phallus impudicus)
The stinkhorn is a truly fascinating mushroom, notorious for its foul smell and phallic appearance. The stinkhorn, true to its name, emits a strong, unpleasant odour that attracts insects, aiding in the dispersal of its spores. Despite its off-putting smell, the stinkhorn poses no real threat to your garden and is genuinely a marvel of nature.
