Corticium salmonicolor

Corticium salmonicolor is a plant pathogen that causes pink disease in a variety of tropical and subtropical tree species. It is a member of the Basidiomycota division of fungi, and is characterized by its distinctive salmon-pink color.

Taxonomy

The species was first described in 1890 by mycologist Pier Andrea Saccardo. It belongs to the Corticium genus, which is part of the Corticiaceae family. The genus name Corticium comes from the Latin word for "rind" or "bark", reflecting the fungus's habit of growing on the bark of trees.

Description and Identification

Corticium salmonicolor is a saprophytic fungus, meaning it feeds on dead or decaying organic matter. It produces a flat, smooth, salmon-pink fruiting body that grows on the bark of infected trees. The fruiting body releases spores, which are spread by wind and rain to infect new hosts.

Distribution and Habitat

Corticium salmonicolor is found in tropical and subtropical regions around the world, including Asia, Africa, Australia, and the Americas. It is particularly common in rainforest environments, where it infects a wide range of tree species.

Pathogenicity and Control

Corticium salmonicolor causes pink disease, a serious condition that can lead to the death of infected trees. The fungus infects the tree through wounds in the bark, and then grows through the tree's vascular system, causing wilting and dieback. Control measures include the use of fungicides, pruning of infected branches, and the use of resistant tree varieties.

Economic Impact

Pink disease caused by Corticium salmonicolor can have a significant economic impact, particularly in rubber and cocoa plantations, where it can cause substantial yield losses.
