Welcome to the summary page for FabulousFusionFood's Wild Food guide to Field Mushroom along with all the Field Mushroom containing recipes presented on this site, with 11 recipes in total.

This is a continuation of an entire series of pages that will, I hope, allow my visitors to better navigate this site. As well as displaying recipes by name, country and region of origin I am now planning a whole series of pages where recipes can be located by meal type and main ingredient. This page gives a listing of all the Cornish recipes added to this site.

These recipes, all contain Field Mushroom as a major wild food ingredient.

The Field Mushroom, Agaricus campestris, (also known as Meadow Mushroom) is a basidiomycete fungus (filamentous fungi composed of hyphae that reproduce sexually) and is a member of the Agaricaceae (Agaricus) family of fungi. Its species name campestris is derived from the Latin word campus (meaning 'field'), and it is found most commonly in meadows either mown for hay or grazed by horses, cattle or sheep. It can be found worldwide and appears in fields and grassy areas after rain from late summer through autumn (but is most common in late August and September, though it can be found as early as June and as late as November). It is fast maturing and has a short shelf-life and ideally should be consumed immediately after picking.

The Field Mushroom grows alone (ie it is not dependent on tree species), gregariously, or sometimes in fairy rings where it tends to stimulate the growth of grass inside the ring. It is closely related to the cultivated white 'button mushrooms' sold in grocery stores but, typically, the Field Mushroom is smaller and rather more delicate in stature, while having the same characteristic mushroom smell.

Young specimens have closed caps and bear tightly-packed bright pink gills that are covered by a veil. As the mushroom matures the cap opens and becomes less and less convex, eventually flattening out. The gills darken becoming brick red then chocolate brown and finally black and slightly mucilaginous. As the fungus opens the veil tears away from the cap, leaving a transient membranous ring which can often become rubbed off. The cut flesh colours slightly pink. Typically the cap is a pure white, but there are variants that bear light brown scales and as the mushroom ages even the white ones tend to develop brown scales near the centre of the cap. The margins of the cap remain inrolled until maturity where they flatten. The stipe (stem) is short and white and bruises brown whilst the flesh bruises slightly reddish and the mushroom has a stronger smell than the shop-bought varieties. The spore print is dark brown.

Maximally the cap grows to between 5 and 10cm in diameter and the stipe is usually between 3 and 7cm tall. It is widely collected and eaten and many consider it the only mushroom safe to consume. If picking in grassland and not near trees it is generally safe to pick. Typically it is confused with the Horse Mushroom, which is safe and good to eat. Care, however, should be taken not to confuse it with the poisonous Yellow Staining Mushroom Agaricus xanthodermus which grows in the same habitat but is distinguished by an unpleasant ink-like smell, its flattened top at the button stage, its white or grey gills (when young) and the cut stem that rapidly yellows. The same is true if you bruise the fungus margin with your thumb. Whilst not fatal it can cause severer gastric upset and diarrhoea in some for several days. The Yellow-staining mushroom is occasional being much commoner in some years than others. Among the similar species mentioned above, there have been cases (in fact the most common cause of fatal fungus poisoning in France) where the deadly toxic destroying angel (Amanita bisporigera) has been consumed by individuals who mistook it for this species. However, the destroying angel has a white spore print and is typically found on mossy ground in mixed woodland, particularly near beach trees. In Britain, this species is exceedingly rare.

Like all Agaricus species field mushrooms lend themselves well to preserving by drying.

Possible Confusion:

The toxic Yellow Stainer (Agaricus xanthodermus), but this mushroom stains chrome yellow when bruised or cut and smells of Indian ink, hospitals or iodine.
