Chrysoporthe Gryzenhout & M.J. Wingf. 2004

The fungi in this genus cause important canker diseases in Myrtales, especially eucalypts. The base and root collars of the trees become infected, resulting in wilt and subsequent death of young trees. Older trees show swollen basal cankers which girdle the stem and cause breakage during high winds.

The following species are currently entered in the system:
