Summer Oyster Mushroom

Summary

The Summer Oyster mushroom, scientifically known as Pleurotus pulmonarius, is a species within the Pleurotus genus, which also includes other well-known varieties like the common Oyster mushroom (Pleurotus ostreatus). However, what distinguishes The Summer Oyster mushroom from other oyster mushrooms is its adaptability to warmer temperatures and its ability to grow during the summer months, unlike other Oyster species that thrive in cooler conditions. Tasty and versatile, the Summer Oyster mushroom is a chef’s favourite during the summer.

The Summer Oyster Mushroom Description and Taste

The cap of the Summer Oyster mushroom typically ranges from 5 to 15 cm in diameter. Its shape starts as convex and gradually flattens as it matures. Depending on environmental conditions and substrate, the cap can vary from pale white to a light brownish hue.

The gills are white to cream-coloured, densely packed, and descending slightly down the stem. The stem is often short and off-centre or absent, which is characteristic of many Oyster mushrooms, such as the Black Pearl King Oyster. It is usually white or light-colored and can be slightly fuzzy or smooth.

How to Store Summer Oyster Mushrooms?

Storing Summer Oyster mushrooms properly is essential to maintaining their freshness, flavor, and texture. The fresher you eat them, the tastier they are. However, the Summer oysters can be stored and have their freshness maintained for longer than most Oyster mushrooms. Here are some best practices for storing these mushrooms:

Refrigeration of summer oysters

• Temperature: Store Summer Oyster mushrooms in the refrigerator at 1°C to 4°C (34°F to 39°F).
• Packaging:
  • Paper Bags: The best way to store them is in a paper bag, which allows the mushrooms to breathe while preventing moisture buildup that can lead to spoilage. Avoid using plastic bags, as they trap moisture and can cause the mushrooms to become slimy.
  • Loose in the Crisper: If you don’t have a paper bag, you can also store them loosely in the crisper drawer of your refrigerator. Cover them lightly with a paper towel to absorb excess moisture.
• Shelf Life: When stored properly, Summer Oyster mushrooms can last up to 5-7 days in the refrigerator.

Freezing summer oysters

• Blanching First: If you want to store them for a more extended period, you can freeze Summer Oyster mushrooms, but it’s best to blanch them first to preserve their texture and flavor.
  • Blanching Process: Boil the mushrooms for about 1-2 minutes, then immediately transfer them to an ice bath to stop the cooking process.
• Freezing Directly: After blanching, pat them dry, place them on a baking sheet to freeze individually, and then transfer them to an airtight container or freezer bag.
• Shelf Life: Frozen mushrooms can last up to 6 months, though they may lose some texture and become slightly rubbery when thawed.

Drying Summer oysters

• Air Drying: You can air dry the mushrooms by spreading them out in a well-ventilated area or using a dehydrator. This method is suitable for long-term storage.
• Storage: Once fully dried, store the mushrooms in an airtight container in a cool, dark place. Dried mushrooms can be rehydrated before use and will keep for up to a year.

Pickling summer oyster mushrooms

• Pickling: Pickling is another option for preserving Summer Oyster mushrooms. They can be pickled in a vinegar brine, which adds a tangy flavor and extends their shelf life.
• Shelf Life: Pickled mushrooms can be stored in the refrigerator for several months.

Summer Oysters Out in the Wild

The Summer Oyster mushroom is primarily found in temperate and subtropical regions worldwide. It is widely distributed in North America, Europe, Asia, and parts of Africa.

The Summer Oyster mushroom commonly grows on dead or dying deciduous hardwood trees, particularly species like beech, oak, and elm. It can also be found on maple, poplar, and other broadleaf trees. It thrives on decaying wood, stumps, and fallen logs, where it helps decompose the wood, returning nutrients to the ecosystem. In some cases, this mushroom can also colonize agricultural waste, like straw or sawdust, when these materials are left in humid environments.
