Albino Thai Lipa Yai (ATLY), also widely known as the "Iceberg" strain, is a leucistic/albino mutation of the classic Psilocybe cubensis Thai Lipa Yai landrace.
The original landrace variety was initially discovered in the village of Lipa Yai on the island of Koh Samui, Thailand, by ethnomycologist John W. Allen. The albino variant was later isolated by "Miss Mush" of So Cal Labs after a rare albino fruit body sprouted during a standard cultivation run of the Thai Lipa Yai variety
