HABITAT

Mushrooms: field

Fields are the open spaces beyond the forest: edges of plowed land, fallow ground, roadsides, village outskirts and vegetable gardens. As in a meadow, there are no trees here, so the main residents are saprotrophs that feed on rich, often fertilized soil.

Field mushrooms are often big and easy to spot: you can see them from afar among short grass or stubble. Plenty of them are tasty edibles, but a field calls for extra caution: nearby roads, fields treated with agrochemicals and look-alike poisonous species all demand your attention.

What makes this habitat special

Field soils are rich in nitrogen, especially where livestock once grazed or organic matter was added. It's an ideal setting for Agaricus mushrooms and parasols. Mushrooms here depend not on trees but on moisture and warmth, so they come up in flushes after rain — from late spring to autumn.

An important point: mushrooms naturally accumulate heavy metals. Don't forage near highways, industrial zones or treated fields, even if the species is edible.

What grows here

1. Horse mushroom (Agaricus arvensis): A large white Agaricus with an aniseed smell, a classic of open ground.

2. Parasol mushroom (Macrolepiota procera): Loves sunny roadsides and fallow land.

3. Giant puffball (Calvatia gigantea): A huge white ball that pops up right in the middle of a field.

4. Shaggy ink cap (Coprinus comatus): Grows on fertilized soil along roadsides and on waste ground; edible only when young.

Questions and answers

Why shouldn't you pick mushrooms near roads and fields treated with agrochemicals?

Mushrooms absorb heavy metals, pesticides and exhaust pollution from the soil and air, concentrating them in the fruiting body. Even a perfect-looking edible mushroom next to a highway or a treated field can be dangerous. As a rule of thumb, forage no closer than a few hundred meters from roads and never on the farm fields themselves.

Shaggy ink cap — edible or poisonous?

A young shaggy ink cap (Coprinus comatus) with firm white flesh is a good edible mushroom. But it «melts» very quickly: within a few hours the gills turn black and dissolve into an inky liquid (autolysis). A mushroom like that is no longer eaten. So pick only young specimens and cook them right away.
