This is an easy species to grow and fruit, ideal for people who are just starting out.

Easily grow your own Black Pearl King Oyster Mushrooms for years to come. Black Pearl King Oyster Mushroom Plug Spawn is wood dowels inoculated with the Black Pearl King Oyster Mushroom species mycelium, and used to grow mushroom fruiting bodies on freshly cut logs or stumps. You will specifically need hardwood logs such as Alder, Ash, Birch, Bitternut, Cherry, Chestnut, Hophornbeam, Ironwood, Maple, Oak, Pecan, Sweet gum, Sycamore, Tulip poplar, Walnut, Willow. Black Pearl King Oyster Mushrooms do not grow on conifers.

Simply drill 5/16" holes 1" deep to hammer the Black Pearl King Oyster Mushroom plugs into. The holes should be drilled right before plugging them, and spaced about 4" apart. Logs should be roughly 6 inches in diameter and four feet long. They need to be freshly cut, or at least cut within the past 20 days. Avoid using logs with missing or split bark, try to find unpenetrated logs, except on the sides they were cut.

Black Pearl King Oyster Mushroom Plug spawn can also be used to grow mushrooms on live trees, but should only be done strategically down branch where pruning is planned later. Our Black Pearl King Oyster Mushroom plug spawn is made from hardwood fluted or spiral dowels.


The Black Pearl Oyster or Black Pearl King Oyster is a oyster mushroom (Pleurotus ostreatus) hybrid from Japan. It is the result of a cross between a European and an Asian Pleurotus ostreatus. It grows and looks much like Pleurotus eryngii (King Oyster) in the beginning as it matures it will look more like a Pleurotus ostreatus (Pearl Oyster). Black Pearl Kings are less finicky than Pleurotus eryngii, and are able to grow very well indoors. Grows on the same substrates as pearl or king oysters such as masters mix or hardwood sawdust (HWFP). It is a fast substrate colonizer that fruits dense, meaty mushrooms.
