Shaggy Inkcap (Coprinus comatus)
Not far from our house is an open area of grass with a scattering of ornamental trees and every October these fungi appear, as if by magic. Every day for a couple of weeks a dozen 'spikes' arise from the ground, by evening they have reached this stage (as I have photographed it). Overnight it continues to develop and the cap separates from the stipe and then by morning the whole things starts to dissolve, the black spores making the liquid look like old fashioned Stephen's ink which some of you will remember from your school days. The liquid soaks into the ground taking the spores with it to start a new generation of the fungus.
Every day the old spikes can be seen dissolving as new spikes appear. This method of spore (or seed) distribution is quite unique to this family of fungi I believe.
It is a widespread species and you can find it on lawns, pasture, along footpaths, on areas of bare ground, even rubbish tips.
