2A1787FCFFE0FFDB90EAF921FE57FE66.taxon	discussion	Notes: — Hawksworth et al. (1979) introduced Bimuria and it was placed in Pleosporaceae based on its sexual morphology. Based on phylogenetic analysis of SSU, LSU, RPB 2 and TEF 1 - α sequence data, Schoch et al. (2009) and Ariyawansa et al. (2014 a) confirmed that the Bimuria novae-zelandiae (CBS 107.79) should be placed in Montagnulaceae (= Didymosphaeriaceae) and related to Tremateia. In this current study, we observed that our novel strain (SQUCC 15280) clusters with Bimuria novae-zelandiae with strong bootstrap support in our phylogenetic analyses (Fig. 1). Therefore, we conclude that it is appropriate to consider our isolate as a species in Bimuria. Bimuria was only known from its sexual morph and we amend Bimuria in order to accommodate its coelomycetous asexual morph from our novel taxonomic account.	en	Wijesinghe, Subodini N., Wanasinghe, Dhanushka N., Maharachchikumbura, Sajeewa S.

2A1787FCFFE1FFDB90EAFE1CFB29F988.taxon	discussion	Notes: — In our DNA sequence analysis, Bimuria novae-zelandiae (CBS 107.79) and B. omanensis (SQUCC 15280) are monophyletic with strong bootstrap support (Fig. 1). Morphological comparison between these taxa are currently impossible as B. novae-zelandiae is known from its sexual morph and only the asexual morph is known for B. omanensis. Comparison of the 570 ITS (+ 5.8 S) nucleotides of these strains reveals 70 (12.3 %) nucleotide differences. This could be due to ITS polymorphisms (Stadler et al. 2020) and it is not surprising that these strains appear to belong to the same species. A comparison of the 852 nucleotides across the TEF- 1 α region revealed 32 bp (3.75 %) differences between these strains suggesting these are distinct species (Jeewon & Hyde 2016). Bimuria novae-zelandiae was isolated from soil of a barley field in New Zealand (Hawksworth et al. 1979). Bimuria omanensis was collected from a decaying leaf of a desert shrub in Ad Dakhiliyah Governorate, Oman. Therefore, based on the molecular data and habitat differences, we conclude that these two taxa are distinct species. Didymosporina aceris, Gordonomyces mucovaginatus and Lichenodiplis lecanorae share similar conidial morphology to Bimuria omanensis (Wijayawardene et al. 2016). Phylogenetically Gordonomyces mucovaginatus and Lichenodiplis lecanorae are not closely related to Bimuria omanensis (data not shown) and sequence data are unavailable for Didymosporina aceris.	en	Wijesinghe, Subodini N., Wanasinghe, Dhanushka N., Maharachchikumbura, Sajeewa S.
