Fungus that lives on dead wood.
Also known as:
Coral spot (Nectria cinnabarina) is a fungus that generally lives on dead branches. The small orange-red raised spots contain the spores. The spores are dispersed by wind and rain. With high humidity and little light, this fungus can also affect live branches.
Remove affected branches generously; cover pruning wound with wound paste. When the fungi appear on the trunk, it is generally too late to control the infestation.
Prune shrubs and trees as much as possible under sunny conditions. Do not plant shrubs and trees susceptible to the menia fungus in the shade.
