Pathologic and taxonomic analysis of leaf spot and tar spot diseases in a tropical dry to wet monsoon ecosystem of lowland Burma.
Foliar diseases due to ascomycetes and/or their anamorphs are described comprising 158 leaf spot and 43 tar spot diseases across a spectrum of some 69 host plant families in tropical, dry to wet, north to south, lowland, central Burma. Families Moraceae, Arecaceae, Euphorbiaceae, Leguminosae, and Poaceae are especially most often attacked. Attack frequency is associated with family size, and the overall diversity of pathogens with the structural complexity of their host. Phenomena, patterns, and concepts pertaining to these ailments are discerned and discussed involving species of Anthostomella, Cochliobolus/Bipolaris, Pyrenophora/Drechslera, Phyllachora and Rhytisma in particular. A host index is included. Collections are held in Herbariums IMI and UC (=LAM).
