Coral Spot Fungus (Nectria Cinnabarina) is a distinctive fungal pathogen known for infecting a range of trees and shrubs, mostly deciduous but apparently sometimes also evergreen.
Identified by its bright coral or orange-red spore-producing structures, the fungus causes small, sunken cankers on infected branches that may exude a red, gelatinous substance during wet conditions.
Common hosts include hardwood forest trees like oak and longhorn, fruit trees like apple and cherry, as well as ornamental plants such as roses and rhododendrons.
Thriving in humid conditions, Coral Spot Fungus has a complex life cycle involving both sexual and asexual reproduction, with asexual spores facilitating its spread.
Control measures involve pruning and removing infected branches, maintaining overall plant health, and employing good garden hygiene practices.
Though specific natural enemies are not well-documented, the soil's complex ecosystem likely harbors microorganisms that play a role in suppressing the fungus.
Coral Spot Fungus is found across North America, Europe, and Asia, and effective disease management strategies should consider the specific plant species affected and local environmental conditions.
