title: Aureobasidium thailandense sp. nov. isolated from leaves and wooden surfaces.
abstract: Aureobasidium thailandense sp. nov. is described from cultures of material collected on leaves and wooden surfaces in Thailand and the type isolate is NRRL 58539(T). Phylogenetically it is distinct from other species of the genus Aureobasidium. Phenotypically it is distinguished by its cardinal growth temperatures, salt tolerance and production of reddish brown hyphal pigmentation in PDA cultures, but micro-morphologically it is not clearly distinguishable from Aureobasidium pullulans. Unlike A. pullulans, A. thailandense sp. nov. produces a non-pullulan extracellular polysaccharide whose characteristics are unknown. The two known isolates of A. thailandense sp. nov. possess an approx. 500 bp type I intron in the 18S rRNA gene that is present in ITS amplifications using primers ITS4 and ITS5. A. pullulans isolates uniformly lack this intron.
