About
Stropharia rugosoannulata, commonly known as the wine cap stropharia, 'garden giant', burgundy mushroom or king stropharia, is an agaric of the family Strophariaceae native to Europe and North America. Unlike many other members of the genus Stropharia, it is regarded as a choice edible and is commercially cultivated. In the kitchen, the Wine Cap is celebrated for its meaty texture and earthy flavor. It can be sautéed, grilled, or added to soups and stews, making it a versatile ingredient in various culinary dishes. Its nutty undertones complement a wide range of recipes, from simple stir-fries to gourmet creations.

Physical Characteristics
Caps:
It is typically broad and convex, with a diameter ranging from 5 to 30 centimeters. The cap's color varies from reddish-brown to wine-red, often with a smooth, shiny surface when young, becoming more wrinkled and slightly faded as it matures.

Gills:
Initially, they are white, but as the mushroom matures, they turn to a dark purplish-brown. The gills are closely spaced and attached to the stem (adnate), sometimes with a slight notch where they meet the stem.
