Burma Landrace
Burma is originally from Yangon, Myanmar, apparently gifted to John Allen who then isolated/domesticated it, this particular Cubensis variety is known for being quicker to colonize fully than the average Cubensis. In my hands they produced these wonderful caps. Landraces are often genetically diverse and have distinctive characteristics that come from adapting to their environment.
