When you use a 1.8 resourcepack in your instance with Botania, the blocks such as Prismarine and Stone variants are not re-textured by the resourcepack. This is due to the Botania's 1.8 textures being in the "botania" assets folder, thus the resourcepack maker has to make duplicate retextures in a seperate "botania" assets folder. If you put the 1.8 textures in a "minecraft" folder with the appropriate .png names they would automatically be retextured if you use a resourcepack. An example is Et Futurum by @ganymedes01 that automatically does this.
