Genus Nectria
Info
Nectria is a genus of Ascomycete fungi. They are most often encountered as saprophytes on decaying wood but some species can also occur as parasites of trees, especially fruit trees (for example apple) and a number of other hardwood trees. Some species are significant pests causing diseases such as apple canker, Nectria twig blight, and coral spot in orchards.

Complex Nectria cinnabarina
Info
Nectria cinnabarina, also known as coral spot, is a plant pathogen that causes cankers on broadleaf trees. This disease is polycyclic and infects trees in the cool temperate regions of the Northern Hemisphere. N. cinnabarina is typically saprophytic, but will act as a weak parasite if presented with an opportunity via wounds in the tree or other stressors that weaken the tree's defense to the disease. A study published in 2011 showed that this complex consists

Frogeye Leaf Spot
(Botryosphaeria obtusa)
Info
Botryosphaeria obtusa is a plant pathogen that causes Frogeye leaf spot, Black rot and cankers on many plant species. On the leaf it is referred to as Frogeye leaf spot; this phase typically affects tree and shrubs. In fruit such as the apple, cranberry and quince, it is referred to as Black rot, and in twigs and trunks it causes cankers.
