Pearl Oyster spore print is collected by placing a mushroom cap (grown indoors) on a piece of paper or aluminum foil and allowing the discharged spores to collect and form a print. Prints can be used to grow mycelium on a sterile petri dish. While we take every precaution to maintain sterility we cannot guarantee prints are completely free of contaminating organisms.
Cultivation Difficulty: Easy
Substrate: Pasteurized straw, wood chips, sawdust, various grains, coffee grounds, agricultural waste, newspaper and cardboard.
Colonization/Fruiting Temperatures: 70-75F/60-70F
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 great candidates for stock oyster mushroom production or 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.
