it's actually the underground hallow and deep corruption. you know how the corruption and hallow can spread through stone and sunflowers in hardmode? well they spread downward too. just keep going down underneath each respective biome until you hit a cave with either ebonstone or pearlstone in it and look for crystal shards for hallow or clingers for corruption.
