What Are Pink Oyster Mushrooms?
The pink oyster mushroom (pleurotus djamor) is a strikingly unforgettable, edible fungi in the family Pleurotaceae. Growing well in warm climates has lead this mushroom to become widely cultivated in Asia. Its vibrant, bivalve-like fruiting bodies are attractive while developing but lose colour quickly upon maturity or when cooked.
What Do Pink Oyster Mushrooms Taste Like?
Pink oyster mushrooms have a much, richer and deeper flavour than its button mushroom counterparts that we’re well accustomed to finding in the supermarket.
The pink oyster mushroom is chewier and ideal for adding to a stir-fry or soup for that extra umami kick. Try crumbing and frying them for an amazing faux-calamari or even slow roasting in the oven for an hour or two with your favourite seasonings and a lashing of olive oil to make some ridiculously tasty, low-carb mushroom chips.
What Substrate Do Pink Oyster Mushrooms Grow On?
Pink oyster mushrooms will grow on a wide range of materials including sugar cane mulch, straw, hardwood, paper and coffee grounds.
For beginners we recommend starting with straw or chopped sugar cane mulch. Supplementation can be added in the form of coffee grounds or bran but will increase the chances of contamination.
Pink oyster mushrooms are considered to be a side-fruiting mushroom compared to the king oyster or button mushroom which are top-fruiting mushrooms.
Opening A Pink Oyster Mushroom Grow Kit
In order to grow, pink oyster mushroom grow kits will need to be opened exposing the fully colonised substrate to fresh air and humidity.
Vibrant pink clusters of coral-like primordia will form on the surface of the substrate. These clusters will develop into mushrooms. At times these clusters may form under the plastic and can either be released to fruit or left to abort.
Primordia formation can be influenced by making a small opening for fruiting and folding the bag tight against the substrate. This will encourage the mycelium to produce primordia close to the cut where it senses both fresh air and humidity.
Please note that pink oyster mushroom is vigorous and will fruit prematurely within the bag if left unattended.
Pink Oyster Mycelium Appearance
Pink oyster mushroom mycelium is incredibly vigorous. Initially it is finer in appearance and structure than white oyster. Pink oyster mycelium is slightly translucent and will turn more opaque as it matures.
The mature spawn will often begin to turn pink within days of colonisation, this is indicative of it preparing to fruit. The maturing mycelium may produce small amounts of a yellow liquid metabolite which is a normal by-product.
Any primordia which has formed prematurely, or in-vitro can be removed prior to using the spawn as usual.
