Parasola plicatilis is a delicate species of fungi that last less then a day.  It can be found singly or in small groups after rain in mown lawns. The cap can be 5 -20mm across. (The one in the photos below was only 5mm across). The cap is translucent and radially grooved, hence named an umbrella inkcap. The centre is yellow brown. The gills are free and at first white, then gray and turning black.
It has a stem of 20 - 60 mm in length. It can be found early in the morning when the grass is wet and because of its delicate structure it can grow and fade within hours.
