Inonotus andersonii, also known as oak canker-rot and heart rot, is a species of resupinate polypore fungus that forms fruiting bodies underneath tree bark. [1] I. andersonii induces canker rot in oak, hickory, cottonwood, and willow trees. [2] [3] Wood that has been infected by this species appears bleached of color and crumbles easily.
A sunken canker then forms as the mycelial fan spreads under the bark. As the hyphae spread, they produce several toxic compounds, the most notable of which is oxalic acid. This acid lowers the pH of the infected tissue from around the normal 5.5 to approximately 2.8, which is toxic to cambium cells.

In short, it is a web and computer program that takes satellite images, aerial photography, and GIS (Geographic Information System) data and superimposes all of this on a 3D globe.
Stem canker on sunflower is caused by the fungal pathogen Phomopsis helianthi (teleomorph = Diaporthe helianthi). [1] There are many "Phomopsis" species that have a broad host range, but "Phomopsis helianthi" is the primary pathogen that infects sunflower, although it has also been seen to infect other, secondary hosts.
