Ink painting/drawing of bean anthracnose, caused by Colletotrichum lindemuthianum.

The painting shows four beans hanging from a stem, and a compound bean leaf with three blades. Small, reddish-brown, sunken circular lesions can be seen on the bean pods. The underside of the leaf petioles have brown lesions on the leaf veins.

Someone on twitter asked “Did you use any software to draw, I will greatly appreciate your answer” [sic]

My pictures are all hand-drawn, but I really appreciate the implied compliment that this is good enough to have been drawn on a computer.
