Field Mushrooms again… Keep ‘em coming

I know the Field mushroom is common, I know there are more exotic mushroom finds out there and I know also that you can never have enough of the great Field Mushroom. I love it so…

The Field Mushroom (Agaricus campestris) is often found in small groups or even rings (though not always, as in this case) but is found commonly in older pasture land and grassland in general, but nowhere near trees of any kind (at least 20 metres from the tree line anyway).

I just wanted to point out and exaggerate the identification tips of this beautifully edible UK mushroom. As well as the typical large white ‘mushroom look’, I’ve shown in the pictures the distinctive pink gills of the younger mushroom (these mature to dark brown), and the ring zone two thirds up the stem, which is very small, sometimes indistinct! So this helps in identification, as the Yellow Stainer mushroom; a sinister (but not deadly) looalike has a much larger, floppy ring zone. See my post on the Yellow Stainer mushroom.

Fairy Rings – Fairy Ring Champignon

This mushroom is the ‘perfect lawn’ mans worst enemy. Although I love them, my dad goes spare at the sight of them – “bloody mushrooms ruining my lawn etc…” – “Natures got no rules man” was my lame hippy reply!

Lawns are the main target ground for Fairy Ring Champignon (Marasmius oreades) – or at least where we may see them the most. It’s a very common mushroom around spring to autumn time. My recent discoveries were late summer (as shown in the pictures) and very recently in mid-september again in my dad’s garden (again)!

Fairy Ring Mushroom‘Champignon’ is the nice French word for ‘mushroom’. It’s a highly prized edible mushroom sold throughout Europe and USA in many markets. To the local wild picker, it can be found in short grass, lawns, parks and pasture land. It is often in rings, although not all the time.

What’s this ‘fairy ring’ thing all about then? We’ve got to get into underground mycology magic for that. The mushroom is the ‘fruit’ of the underground mycelium, or organism that is the fungi (a network of fine white filaments known as hyphae). Mushrooms are born to deliver their spores in the breeding process.

In short, the mycelium expands as it grows outwards from a central position. The older, central zone dies off and at the edges of this ring is where the mushroom grows. Die hard gardeners are extra miffed because the grass around the ring dehydrates and dies too (helped along by fungal cyanide toxins). The outer grass region is a nice and green affair due to the hungry, feeding mycelim.

Some of these ‘fairy ring’ organisms have lasted for hundreds of years and more (not just our Marasmius oreades) and can reach up to a mile in diametre. They are are truly wonderful organisms that seem to break all kinds of records. But that’s another story for a later date.

Recently, I have seen many Fairy Ring Champignons collections. Some were but a few, others in partial rings and only one as a giant ring in pasture land of about 4 metres in diametre. The caps (or heads) of these beauties are the best edible part. Just discard the stems as they are just too tough and not worth it. Make sure you get them when they’re young – you won’t make a mistake because the older ones just look unapetizing anyway! Check out recipes online. They’re also good for pickling as they hold their shape and don’t disintegrate. Hope you find as many as I have.

Fairy Ring Champignon - Edible Mushroom

Although not in a ring this time – here’s a few of the Champignons on a lawn

See how the ring is formed in this patch of grass. The outer edge, where the mushrooms are growing, are stimulating the grass growth. The centre of the grassy patch will eventually die off.

The Genus MARASMIUS (Parachutes): Characteristics to look out for:

• Small or tiny caps with tall, thin stems.
• Convex ‘umbrella’ or ‘parachute’ shaped caps.
• The Fairy Ring Champignon is one of the larger species in this genus
