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.
