You would not believe what DNA studies are doing to fungal taxonomy. Looks are turning out to be near irrelevant... even families are being messed up.
Fungal taxonomy has always been a mess. The very large group of Fungi Imperfecti was nothing but a catch-all for anything that couldn't be more clearly defined. While, periodically, some member of the Fungi Imperfecti would get moved out into the Ascomycetes or Basidiomycetes, more were being added at the same time.
20 years from now we might have a good picture of the whole fungal mess.
