Ink painting/drawing of Puccinia graminis aecidium, with aecidiospores, on a barberry leaf.

The painting shows a single aecidium on a barberry leaf. Chains of aecidiospores are shown in pink. Below the aecidium, there is a mass of hyphae amongst the host cells.

This painting is paired with my Wheat Stem Rust painting, which shows Puccinia graminis on its alternative host.
