Coral Spot - Nectria cinnabarina

Barnet, London, UK, June 2018

Coral spot fungus (Nectria cinnabarina)

This fungus is a weak parasite on broadleaf trees; it tends to attack trees already weakened by disease, injury, or drought, or else saprophytically attach to dead wood. In an infected tree, you may first notice die-back of smaller branches, before the orange-pink spots emerge from the bark (this is the sexual stage, see above); these will then mature into an asexual stage in the form of hard, red spots. It produces spores during both stages, and in this way reproduces both sexually and asexually.

Hibiscus canker, coral spot

Today at work I got to diagnose my first severe fungal outbreak, suddenly very evident on these Hibiscus syriacus plants as real spring approaches. They looked fine last time I had checked them, but I knew something was wrong when I noticed most of their branches were suddenly clearly dead. We had a really hard winter, but the real culprit was actually a fungus -Nectria, most likely N. cinnabarina, the coral spot- which I had also noticed on an Acer a couple of months ago. 

This fungus is widespread in cool, temperate areas of the Northern Hemisphere and recognisable due to the bright orange fruiting bodies which erupt from cankers in the fissured bark. There is no known cure, but it might be prevented by avoiding damage to the trees and contained with pruning and good hygiene practices. Unfortunately, there was no way for me to save a few heavily infected young plants.

PRÉSENTATION La maladie du corail est une maladie cryptogamique. En fait il s’agit d’un champignon nommé Nectria Cinnabarina qui en est responsable. Pourquoi maladie du corail  ? Tout simplement à cause des petits coussinets couleur corail laissés sur les troncs ou sur les rameaux des arbres et des arbustes. (more…)

September ‘17 - Coral spot - Nectria cinnabarina

The Coral Spot Fungus (Nectria cinnabarina) is a fungal species of plant pathogen that causes cankers on broadleaf trees. It thrives in the cool temperate regions of the Northern Hemisphere. It can be found all year round. The infection mostly only impacts plants that are already weakened because it is known to be a rather weak pathogen. The causal fungus is very commonly found growing as a saprophyte (meaning it is a fungus that feeds on detritus) on dead wood. Spores from the pink pustules on the bark are dispersed by rainfall.

Coral spot fungus treatment isn't possible. There are no effective fungicides. Smaller branches and those that have been pruned or broken are usually the ones that begin dying after they are infectes. Once the branch has died, you see the actual fungus. It will produce pink or coral-colored small blobs on the dead wood.
