Identification and Characteristics


The cap of the King Stropharia typically measures 1.5 to five inches across and can vary in shape from convex to flat as the mushroom matures.

It is known for its dark red or burgundy color, which earned it the name ‘wine cap’. The cap surface may have a slightly slimy texture when wet, and the margin can be slightly inrolled.


The stem of this mushroom ranges from three to six inches in length.

One key characteristic of the King Stropharia stem is the presence of a ring, also known as the annulus. The ring on the King Stropharia stem is unique, as it has indentations from the gills along the top, giving it a lined appearance.

This lined ring is considered one of the most diagnostic features of this mushroom.


The gills of the King Stropharia are initially white or pale gray, turning purplish-gray or dark purplish-brown as the spores mature. They are attached to the stem and are often crowded. Acanthocytes, or small, spiky cells, can be found at the edges of the gills.

Spore Print

The spore print of the King Stropharia is purplish-brown in color. A spore print can be obtained by placing the cap, gills down, on a piece of paper for a few hours to collect the falling spores. This color can help distinguish the King Stropharia from other similar looking mushrooms.

Cultivation and Growth

King Stropharia mushrooms, also known as wine caps or garden giants, are a popular choice for home cultivation due to their delicious taste and simple growth requirements.


There are different substrates that can be used for the growth and cultivation of King Stropharia. Some of the commonly used substrates are wood chips, hardwood chips, straw, and cardboard. These materials provide a suitable environment for the mushrooms to grow and thrive.

Wood Chips and Sawdust

An ideal substrate for growing King Stropharia mushrooms is fresh, untreated hardwood wood chips. Sawdust can also be used as a supplement or alternative.

Pine or coniferous wood chips should be avoided for this mushroom species. It is essential to ensure the substrate is as sterile as possible to reduce the risk of contamination from other fungi or bacteria.

Straw and Cardboard

Another option for cultivating King Stropharia mushrooms is using a mixture of straw and cardboard. The straw should be soaked in water before being added to the substrate, while cardboard can be torn into smaller pieces and layered with spawn for optimal mushroom growth.

Moisture and Compost Pile

Maintaining the right amount of moisture is critical for the successful cultivation of King Stropharia mushrooms. The medium should be damp but not wet to prevent contamination.

To maintain the required moisture, you can incorporate the substrate into a compost pile. This method helps to retain moisture and provides additional nutrients for the mushrooms.

Fruiting Conditions

Fruiting conditions are necessary for the mushrooms to grow and reproduce. The substrate should be covered with a layer of potting soil, and a handful of native soil should be added to introduce native microbes.

Wet the soil thoroughly and add one to two inches of the potting soil on top of the surface. Maintain a moist environment and provide adequate sunlight exposure for the mushrooms to fruit successfully.

By carefully selecting the right substrate and providing the proper fruiting conditions, you can enjoy a successful harvest of delicious King Stropharia mushrooms.

Harvest and Storage

To harvest wine cap mushrooms, gently twist the mushroom stem to remove it from the substrate or use a knife to cut it at the base. Be sure to pick them while they’re still young, as their texture and flavor are best at this stage.

When it comes to storage, follow these guidelines for optimal freshness and taste:

Before storing, clean the mushrooms by gently brushing off any dirt or debris. Avoid washing them, as this can cause them to become soggy.

For short-term storage, keep the fresh king stropharia mushrooms in a paper bag or a covered container lined with paper towels. Place them in the refrigerator, where they can last for up to a week.

For long-term storage, consider drying, freezing, or pickling the mushrooms.


To dry them, slice the mushrooms and place them on a rack or tray in a well-ventilated area. Once dry, store them in an airtight container in a cool, dark place.


To freeze, clean and slice mushrooms, then lay them on a tray in the freezer. Once frozen, transfer them to a sealed container or ziplock bag.


Pickling king stropharia mushrooms involves cleaning, slicing, and adding them to a vinegar-based brine, then storing them in a sterilized jar.

By following these guidelines, you can enjoy the delectable flavor and unique texture of king stropharia mushrooms for an extended period, ensuring your harvest doesn’t go to waste.
