Tubercularia lateritia

About

Tubercularia lateritia is a fungal saprobe or plant pathogen that sometimes infects avocados and macadamia trees. It grows mostly on decaying bark and rotting wood in tropical countries. It is an asexual fungus (anamorph) and is correctly known by the different name used for its sexual state (teleomorph), Nectria pseudotrichia. The asexual state and sexual state are often, but not always, found together.
