Modding Help Problem with adding a microdungeon

I added a new microdungeon and placed in .surfacebiome file of my biome code that generates this microdungeon, but it isn't generating, and in the log I found that:

Code:

Error: Failed to place microdungeon StarException: Unknown dungeon: 'fleshhause'
  0063DF3F
  007A74E3
  00798DF9
  00798EF2
  00790338
  007902F4
  007905B7

  0069D9CB
  009447CC
  759833AA
  778C9EF2
  778C9EC5

I added this microdungeon to whitelisted microdungeons in planetgen.config.
I added that do this directory:
.../assets/dungeon/microdungeon/fleshhause/<here are the files>

And, if this possible, how to create a minidungeon only for one biome?
