摘要：Two Guignardia species collected in northern Thailand differ morphologically from previously known Guignardia species recorded on palms. Guignardia bispora sp. nov. is distinguished by having two ascospore types and G. ellipsoidea sp. nov. is distinguished by having reduced mucilaginous appendages compared to the holotype of G. candeloflamma , also found on palms. The new species are described and illustrated and compared with similar taxa
