This is the common temperate Oyster mushroom. Depending on substrate, light and temperature, Pearl oysters will vary in coloration from white to gray and brown. Generally, more intense light will produce a darker coloration. Pearl Oysters are an adaptable species that fruits easily on a wide range of substrates and are good candidates for recycling wood and paper waste into edible mushrooms.

As with all oyster mushrooms, Pearl oysters need plenty of fresh air to develop normally. High carbon dioxide levels from mushroom metabolism will accumulate in sealed growing environments and can reduce cap size and elongate stems severely. Fruiting in open humidity chambers with frequent fresh air exchange will produce best possible yields.
