Panellus serotinus: The Ultimate Mushroom Guide
About The Panellus serotinus Mushroom
Panellus serotinus aka Sarcomyxa serotina is a thick-gilled mushroom with an oyster shell shape and olive color. It grows on hardwood logs, especially sugar maple, beech, and oak. Logs can be inoculated just as you would for Shiitake.
This mushroom tends to fruit in groups, either in clusters or single.
Its velvety olive or toffee-colored caps are excellent culinary mushrooms, fresh or dried. Fresh mushrooms, when sliced and sauteed, are buttery in texture, much like Chicken of the Woods. In Japanese culture, late fall oysters are considered a very popular edible mushroom although it is not as common in North America.
Other names: Olive Oysterling, Late Oyster, Mukitake.
