A crop of toadstools

In the pouring rain of a grey mid-November day I noticed, through our French windows, some toadstools growing in Wbx.  On closer inspection in better weather conditions next day, they were clearly one of the smaller Coprinus but overnight had started to autodigest around the edges into the inky black liquid characteristic of this genus.

In all I counted about ten fruiting bodies in different places, so the mycelium must spread widely through the window box soil.
