Elm Oyster (Pleurotus ostreatus) is a fast substrate colonizer that produces large dense mushroom clusters. They are light beige in color and have a subtle woody, earthy flavor. Elm oysters are reliable indoor year-round producers. If kept in the right conditions, they will yield substantial first, second, and even third harvests. They have a low spore load (which is great for cleanup) but do have a slightly shorter shelf life than other oyster mushrooms.
Elm oyster grain spawn can be used for indoor production using sawdust or straw or outdoor production using straw or wood chips.
