Basil - Downy mildew under a microscope

Downy mildew on basil under a microscope

This is a picture of sporangiophores, tree-like structures that serve as 'stalks'. The round to lemon shaped structures are sporangia-fruiting bodies that release the zoospores. The sporangia are blown or splashed around and release zoospores to infect.
