Fruits after good rain when nights turn cool, typically following late summer and autumn downpours. A warm spell broken by steady rainfall brings them up within a day or two, often in flushes.
Late summer to autumn, roughly July to November, with most fruiting from August onwards.
A tall white cap, at first cylindrical and shaggy with upturned scales, sitting like a fingertip over the slender white stem. The gills are white when young, then turn pink and finally dissolve from the rim upwards into a black inky liquid as the cap opens.
Does not keep; it auto-digests into black liquid within a few hours even in the fridge, so cook on the day of picking. To hold a meal briefly, cook them down first and refrigerate or freeze the cooked mushrooms rather than the raw caps.
Eat only very young, white, firm caps; slice and fry gently in butter as they release a lot of liquid, then finish with cream and parsley. Good in a quick soup or folded into an omelette, but always cook the same day they are picked.
Most similar to the common ink cap, Coprinopsis atramentaria, which is greyer and smoother without the shaggy scales. That species causes severe illness if eaten with alcohol, so the key difference is the tall shaggy white cap of Coprinus comatus versus the smooth grey, bell-shaped cap of the common ink cap.
