1) To investigate the diversity of Mycosphaerella and related genera from Northern Thailand, and to determine the degree of host-specificity of these fungi.
2) To examine the morphology and the phylogeny of Mycosphaerella and related genera from Northern Thailand.
3) To describe and document the newly found and previously unstudied Mycosphaerella and related genera from Thailand.
4) To resolve and clarify the phylogenetic relationships and anamorph-teleomorph connections among Mycosphaerella and related genera for which the taxonomic status is largely unknown.
