Never eat a wild mushroom identified from a website. This one helps you rule things out. It cannot rule anything in.

Stropharia rugosoannulata

Never eat a wild-foraged mushroom you identified from a website, this one included. Wild mushroom misidentification can be fatal, and no page can rule a specimen IN. This reference is about cultivated and shop-bought mushrooms only: species you buy, or grow from bought spawn, where there is nothing to identify. To identify anything wild, consult a qualified local expert holding the actual specimen, never a description on a screen.

In the kitchen

Flavour

Mild, with a potato-and-red-wine note some compare to red wine; young firm buttons are the ones to take.

Texture

Thick, firm flesh in young specimens, going soft with age. Solid enough to grill.

In the kitchen

Take young firm buttons; larger opened caps go soft. The thick flesh survives the grill better than most, and it also roasts and sautes well. Cook it through.

How it is cultivated

Substrate

A bed of fresh hardwood chips or straw in a shaded corner of a garden, spread with spawn. Pasteurising is not needed; the bed is meant to be open to the ground.

Fruiting temperature

Warm-season fruiting, roughly 15-30°C (60-85°F), spring through autumn

Humidity

Keep the bed damp; it fruits after rain

How it is grown

Outdoor wood-chip or straw bed

Time to first harvest

8 to 16 weeks in the first season, then each year after

How much, how long

Fruits for years and can out-produce a household

Difficulty at home

Beginner. The easiest way into growing after a kit: an outdoor bed needs no sterile work and produces heavily for years.

What is worth knowing about it

The classic beginner's outdoor crop, and a genuine garden workhorse: a shaded wood-chip bed spread with spawn fruits for years, needs almost nothing, and doubles as a path or mulch. Because you inoculated the bed, you know what is coming up.
