Smuts, Periconia, Myxomycetes: Smuts and Myxomycetes are parasitic plant pathogens and can produce type I fungal hypersensitivity reactions. There are occasions where Periconia have been implicated in mycotic keratitis, but this is a rare event. All three are typically grouped together due to their association with plants, the outdoors and because they share similar microscopic morphology.
