Ascorhombispora is a new genus characterised by superficial, dark brown to black perithecial ascomata; bitunicate, swollen saccate asci; and dark brown, 3-septate trapezoid ascospores with a wide septum band. The 28S rDNA and 18S rDNA regions of this fungus were amplified and sequenced. Phylogenetic analysis was conducted in order to infer systematic placement of this fungus. Results show that Ascorhombispora aquatica nests within Pleosporales (Dothidiomycetes, Ascomycota), which corroborate with the morphological prediction.
