I recently received a zygopetalum from a friend, and sadly, I've discovered these black spots on the leaves! The older leaves are most stricken, though some younger growth is as well.The spots are mostly the size of roughly ground pepper, and are pitted/indented. What could this be? phyllosticta? I've also noticed it on my bulbo! I've had an uh-oh moment and cut away the more heavily spotted sections, though some peppery spots are still on some parts of each plant.
