Pale Oyster Mushroom
Pale Oysters are mainly a mushroom of the warmer months but can occasionally be found at any time of year. It can be hard to tell the difference between a pale Grey Oyster and a darker Pale Oyster mushroom, they generally grow at different times of year but are thought to hybridise making identification even harder.

Cap
White/off white to pale grey/brown emerging in ‘shelves’ laterally from the medium they are growing in. Generally shell or fan shaped developing uneven or lobed edges with age.
Gills
White to off white/tan with age, crowded and very decurrent, running all or almost all the way down the underside.

Can have a stem like growth emerging from the wood it is growing from or the fruiting body/cap can grow straight from the tree.
Flesh
White, firm and meaty.
Possible Confusion
Angels Wings are similar but are very thin, unlike Pale Oyster mushrooms. They can be deadly poisonous to some people so should be avoided
Olive Oysterling looks similar but is more olive coloured and has darker gills, even when young. This mushroom is reported as edible so it shouldn’t cause any problems with misidentification.
The Grey Oyster, Plurotus ostreatus ,pictured, is very similar but is grey/blue coloured and grows in the colder months, unlike the warm loving Pale Oyster Mushroom. It is thought the two can hybridise making identification sometimes very difficult.
Spore Print
White. Cylindrical.
Frequency
Common.
Other Facts
Oyster mushrooms are omnivorous, digesting dead organic plant matter and catching nematode worms with lassos of mycelium, then entering the worms mouth and digesting them from the inside. this provides the mushroom with nitrogen.
