Star Pinkgill?

Smell and taste mealy, 2-2.5cm across the cap and fruitbody about 6cm tall. Growing on unimproved grassland. There was atleast one other patch of this or very similar species around. There were other Entolomas around that looked slightly different. The Star Pinkgill is called such because of the knobbly shape of the spores when looked at under the microscope. The latin name is also descriptive since this mushroom commonly grows in groups or troops and 'conferendum' means a collection or gathering.
