The idea
Chytridiomycota, the chytrids, are the simplest true fungi, mostly aquatic, and the only fungal phylum to retain flagellated gametes and zoospores.
In practice
The chytrid Batrachochytrium dendrobatidis parasitizes amphibian skin, a factor contributing to declines in frog populations worldwide.
Where people slip
Retained flagella mark chytrids as structurally primitive among fungi— every other fungal phylum has lost flagella.
