Soil-borne (Hypocreales, Nectriaceae) associated with plantations in Colombia.

spp. are widely planted in Colombia as an important component of a growing paper and pulp industry. Leaf and shoot blight caused by spp.

and Its Newly Discovered Sexual State Causing a Serious Needle Disease of spp. in Colombia.

Brown spot needle blight (BSNB), caused by the fungal pathogen , is a well-known disease of spp. in several northern hemisphere countries. In the southern hemisphere, this disease has been reported only in Colombia and, apart from a single report of severe defoliation of plantations in the early 1980s, has not caused serious damage in this country.

Endophytic Cryphonectriaceae on native Myrtales: Possible origin of Chrysoporthe canker on plantation-grown Eucalyptus.

Chrysoporthe austroafricana (Cryphonectriaceae) is a damaging canker pathogen on Eucalyptus species in Southern Africa. Recent studies have shown that the fungus occurs on native Syzygium species and that it has apparently undergone a host range expansion from these native trees to infect non-native Eucalyptus. The aim of this study was to consider whether Chr.

Novel hosts of the Eucalyptus canker pathogen Chrysoporthe cubensis and a new Chrysoporthe species from Colombia.

The pathogen Chrysoporthe cubensis (formerly Cryphonectria cubensis) is best known for the important canker disease that it causes on Eucalyptus species. This fungus is also a pathogen of Syzygium aromaticum (clove), which is native to Indonesia, and like Eucalyptus, is a member of Myrtaceae. Furthermore, C.

Aurapex penicillata gen. sp. nov. from native Miconia theaezans and Tibouchina spp. in Colombia.

Conidiomata of a fungus resembling Chrysoporthe cubensis, a serious canker pathogen of Eucalyptus spp. (Myrtaceae, Myrtales) in tropical and subtropical parts of the world, was found on Eucalyptus grandis in Colombia. Fruiting structures of the fungus could be distinguished from those of C.
