Article Abstract
The family of Cryphonectriaceae (Diaporthales) contains many important tree pathogens and the hosts are wide-ranging. Tree species of were widely planted as ornamental trees alongside city roads and villages in southern China. Recently, stem canker and cracked bark were observed on 2-6 year old and in several nurseries in Zhanjiang City, Guangdong Province, China. Typical conidiomata of Cryphonectriaceae fungi were observed on the surface of the diseased tissue. In this study, we used DNA sequence data (ITS, , , ) and morphological characteristics to identify the strains from Terminalia trees. Our results showed that isolates obtained in this study represent two species of , one previously described species, , and an unknown species, which we described as sp. nov. Pathogenicity tests demonstrated that both and were able to infect and two tested clones, suggesting the potential for fungi to become new pathogens of .

Cryphonectriaceae is a diaporthalean family containing important plant pathogens of which is the most notorious one. An emerging stem blight disease on (Elaeocarpaceae) and was observed in Guangdong Province of China recently. Typical Cryphonectria blight-like symptoms including cankers on tree barks with obvious orange conidial tendrils were observed.

(Myrtales, Myrtaceae) trees in Hawaii are severely affected by a rust disease caused by (Pucciniales, Sphaerophragmiaceae), but they are commonly co-infected with species of Cryphonectriaceae (Diaporthales). In this study, and other trees in the Myrtales were examined on three Hawaiian Islands for the presence of Cryphonectriaceae. Bark samples with fruiting bodies were collected from infected trees and fungi were isolated directly from these structures.

Emerging fungal pathogens are a threat to forest and agroecosystems, as well as animal and human health. How pathogens evolve from nonpathogenic ancestors is still poorly understood, making the prediction of future outbreaks challenging. Most pathogens have evolved lifestyle adaptations, which were enabled by specific changes in the gene content of the species.
