Barriopsis tectonae sp nov a new species of Botryosphaeriaceae from Tectona grandis (teak) in Thailand

Abstract

Tectona grandis (teak) is an increasingly important timber resource globally. It is native to Asia, including Thailand. In this paper a new species of Barriopsis, B. tectonae sp. nov., is described from a dead T. grandis branch collected in Thailand. Barriopsis tectonae can be differentiated from the two previously described species of Barriopsis; B. fusca and B. iraniana, by its ascospore and conidial dimensions. Phylogenetic evaluation of the ITS, TEF1-α and BT genomic regions provide further evidence that B. tectonae is a novel species.
