If this is the blusher, it is a close relative of, and frequently confused with, panther caps.
This grouping was within yards of the others posted a couple of days ago which seemed more definitely to be panther caps.
Now grown beyond its earlier state here.
The inkcaps are a family of mushrooms which spread their spores by deliquescing. Their caps are transformed into a black slime, which is indeed the pores.
Another name for this species is lawyers wig. At a certain stage in their decomposition the caps can look very like a barrister’s less than pristine headgear (below and especially above).
The specimens pictured here show the range of stages from newly emerged to almost completely deliquesced.
