Translated from the Dutch Mycological Society:
Very rare russulas after it rained cats and dogs
Wednesday, July 11, 2012
In the Reigersdaal area in Heerhugowaard after the abundant rain recently the very rare Russula elegans appeared. Russula elegans is an endangered species on the Red List. Only a few times it had been found with certainty in the Netherlands. Although most russulas appear later in the year, it seems that Russula elegans especially responds to abundant precipitation whether in summer or in autumn.
Dear Kitty. Some blog 
cute little umbrella 🙂 these are very healthy and pretty. I don’t know why these are said to be rare? I have seen many such kind of mushroom every rainy season in my neighborhood.

Hi, welcome to my comment box 🙂
Are you sure that the ones which you have seen are the Russula elegans species? Or maybe a related species?
The Russula genus has about 750 species; some common, some rare. Many species are difficult to distinguish from other species.

It can be very tricky to identify this species. The Dutch Mycological Society: says that Russula elegans also grew on the same spot two years ago; but then they misidentified it as another Russula species.
