Rostraureum tropicale is a species of fungus from genus Rostraureum that is found in Ecuador.

Distribution and habitat

Rostraureum tropicale is a

cankers on dying trees. The fungus is distributed in the lowland tropics of Ecuador.[1] Hosts include Terminalia ivorensis and Terminalia superba (both in family Combretaceae of the Myrtales
).

Morphology

ascospores are one-septate and fusoid to ellipsoid
.

Rostraureum tropicale can be distinguished from

perithecial necks are not embedded in well-developed stromatic tissue. Additionally, it can be distinguished from Chrysoporthe by the presence of orange perithecial necks instead of fuscous-black necks.[1]

Phylogeny

Rostraureum tropicale is

β-tubulin DNA sequences. However, species of Chrysoporthe and Cryphonectria belong to the same superclade and are thus closely related to Rostraureum tropicale.[1]

Pathogenicity

Rostraureum tropicale is pathogenic towards Terminalia ivorensis and a closely related host, Terminalia superba, causing well-developed stem cankers within six weeks of inoculation. It is also more pathogenic than Chrysoporthe cubensis, which causes smaller lesions on Terminalia superba.[1] However, C. cubensis is not usually a pathogen of trees in the Combretaceae.[2]
